In this episode, we discuss patellofemoral pain (PFP). We explore:
- What is happening structurally in PFP?
- Differential diagnosis around the knee
- Role of effusion and crepitus in PFP
- Assessment of patients with suspected PFP
- Role of squatting in objective assessments and treatment
- What factors may lead to chronicity
- Evidence based management of PFP
- Role of blood flow restriction within PFP

00:00:04.719 --> 00:00:15.279
On today's episode of Physiodisgust, we dive into the world of patelephemoral pain with two outstanding guests, Claire Robertson and Professor Lisa Hogland.
00:00:15.519 --> 00:00:22.960
Claire is a consultant physiotherapist and internationally recognised knee specialist, often referred to as the patellophemoral queen.
00:00:23.280 --> 00:00:30.640
With decades of clinical experience, she's helped countless patients and clinicians better understand and manage patellaphemoral pain.
00:00:30.879 --> 00:00:44.079
Lisa is a professor at Thomas Jefferson University in Philadelphia, Pennsylvania, USA, and a leading researcher and physiotherapist whose work focuses on knee pain, biomechanics, and rehabilitation strategies.
00:00:44.240 --> 00:00:53.359
Her research has shaped how we view risk factors, prevalence, and management approaches across diverse populations, from athletes to military recruits.
00:00:53.520 --> 00:01:00.079
Together, we unpack what telephemoral pain is, how it presents, and what clinicians should look out for.
00:01:00.240 --> 00:01:10.000
We discuss risk factors, differential diagnoses, and management strategies while also exploring the latest research, adjunct, and future direction in treatment.
00:01:10.319 --> 00:01:18.640
This is a must-listen for clinicians wanting to sharpen their approach to one of the most common and often tricky presentations in practice.
00:01:18.879 --> 00:01:22.239
I'm James Armstrong and this is Physiodisgust.
00:01:23.519 --> 00:01:31.439
Claire Lisa, it's great to have you on the Physio Disgust podcast today to talk all about patellophemoral pain.
00:01:31.599 --> 00:01:36.319
So tell us just a brief introduction of where you're both coming in from today.
00:01:36.799 --> 00:01:38.239
Thanks for the welcome, James.
00:01:38.400 --> 00:01:42.959
I'm coming to you from Philadelphia, Pennsylvania, in the United States.
00:01:43.200 --> 00:01:48.879
And by way of background, I'm a physical therapist, a physiotherapist all around the world.
00:01:49.040 --> 00:01:51.439
And I am also in academia.
00:01:51.599 --> 00:02:00.959
I'm a researcher, and my primary area of research relates to patelephemoral pain and other iterations of that, including patelephemoral osteoarthritis.
00:02:01.120 --> 00:02:02.000
So happy to be here.
00:02:02.319 --> 00:02:02.719
Brilliant.
00:02:02.799 --> 00:02:04.159
And great to have you on, Lisa.
00:02:04.319 --> 00:02:04.640
Claire.
00:02:05.040 --> 00:02:05.760
Hi, James.
00:02:05.920 --> 00:02:07.040
Thanks and Lisa.
00:02:07.120 --> 00:02:08.400
Thanks for the invite also.
00:02:08.800 --> 00:02:16.080
So I'm in London in the UK, and I'm a clinician just seeing patients with patellifemoral pain.
00:02:16.159 --> 00:02:21.360
A little bit of ITB of fat pad thrown in, but patelephemoral pain at second opinion service.
00:02:21.520 --> 00:02:28.479
I'm also a researcher and teach all around, yeah, and anything to do with patelephemoral pain as well.
00:02:28.719 --> 00:02:29.199
Wonderful.
00:02:29.360 --> 00:02:30.400
So we're going to get stuck in.
00:02:30.479 --> 00:02:42.400
We've already said before we we started the recording that this is a huge topic, a very specific area of pain, a presentation around the knee, but one that has an awful lot of meat around the bones, if you like.
00:02:42.479 --> 00:02:43.680
So there's lots we could talk about.
00:02:43.840 --> 00:02:50.080
But we're going to do our best to pull out some real clinical pearls for listeners today to be able to take away into their practice.
00:02:50.319 --> 00:02:56.639
The best thing to do, as always, is to start with a bit of definition and introduction into what we mean by patelephemoral pain.
00:02:56.719 --> 00:02:59.759
Claire, do you want to kickstart us with when we use this term?
00:03:00.000 --> 00:03:02.639
What are we talking about in overall terms?
00:03:02.960 --> 00:03:13.599
Yeah, well, that in itself is an interesting point because I think we need to view it as a really big umbrella term, but in essence, we're talking about pain arising from the patelephemoral joint.
00:03:13.919 --> 00:03:18.000
That doesn't mean there needs to be the presence of any structural damage.
00:03:18.159 --> 00:03:23.599
And very often, particularly in our adolescence, there's a complete absence of structural damage.
00:03:23.919 --> 00:03:30.719
So we're looking at often a vague distribution of pain, maybe anterior, but not necessarily.
00:03:31.039 --> 00:03:35.599
We're looking at characterizations, particularly of what aggravates the patient.
00:03:35.759 --> 00:03:37.280
So it's often loaded flexion.
00:03:37.360 --> 00:03:44.240
So sit-to-stand, stares, returning, coming out from a crowd, they're very much the hallmarks.
00:03:44.719 --> 00:03:53.120
We might also view it as a diagnosis of exclusion when we know that we're excluding other pathologies that may create pain at the knee.
00:03:53.439 --> 00:03:55.759
Lisa, anything to add to that from your point of view?
00:03:56.240 --> 00:03:57.599
I completely agree with that.
00:03:57.759 --> 00:04:09.360
What Claire said really, she very nicely summarized what the Academy of Orthopedic Physical Therapy, our patelephemoral pain clinical practice guideline, we really focused on three factors.
00:04:09.599 --> 00:04:22.319
The first is that location of pain being peripatellar or retropatellar, and that it is something that is provoked by or aggravated by those loaded flexed knee activities.
00:04:22.560 --> 00:04:27.439
Squatting is a big one, rising from the squat, et cetera, descending stairs.
00:04:27.680 --> 00:04:35.360
And then the other third important point was to exclude any other condition that might be a cause of that patient's symptoms.
00:04:35.680 --> 00:04:49.839
Both of you have alluded to there that that subjective history is giving you quite significant clues there when outside of the mechanism of injury, away from any trauma, those sorts of things that patients might present with, which we're going to talk about more later on.
00:04:50.079 --> 00:04:54.959
Are there any populations that we see that will are more likely to present with this condition?
00:04:55.519 --> 00:05:02.720
Actually, you can see it across all different ages, but I think there are some sort of clusters, if you like.
00:05:03.040 --> 00:05:10.879
So we've got our adolescence, which is often, I'm sure we'll talk about it often around excess sporting and athletic load.
00:05:11.120 --> 00:05:19.439
We then have perhaps another cluster is where there's been a rapid change and a deloading, and then perhaps an attempt at reloading.
00:05:19.519 --> 00:05:24.720
So the clo the thing that comes to mind there would be a young, new mum who's trying to get back into a running.
00:05:25.040 --> 00:05:35.600
We've also got our sort of hypermobiles and perhaps our weaker patients who it's not to do with athletic load, it's to just to do with insufficient strength.
00:05:35.759 --> 00:05:44.240
And then obviously as we go through the advancing years, we might then be then looking more into on a spectrum with catella from osteoarthritis.
00:05:44.560 --> 00:05:47.519
So is we're looking at a wide range of age groups?
00:05:47.680 --> 00:05:54.240
Is there any sort of statistics around this in terms of what we see in practice across, not just in the United Kingdom, but across the globe?
00:05:54.480 --> 00:05:55.839
Lisa, do you anything on that?
00:05:56.160 --> 00:05:58.399
Yes, and I completely agree with what Claire is saying.
00:05:58.480 --> 00:06:11.680
The one one other group that I think she didn't mention that it is quite prevalent in is the military population, those individuals, young adults in their basic training, for example, it's quite common in those.
00:06:11.839 --> 00:06:14.160
So it's really, we think a lot about adolescence.
00:06:14.480 --> 00:06:16.240
The first one that you mentioned, Claire.
00:06:16.399 --> 00:06:21.519
The general population, actually, general population, the prevalence is about 23%.
00:06:22.319 --> 00:06:24.399
And with adolescence, 29%.
00:06:24.959 --> 00:06:29.279
That's from an article by Smith that was published a few years ago.
00:06:29.439 --> 00:06:33.600
And then it's individuals with high levels of physical activity.
00:06:33.839 --> 00:06:38.399
So that could be your runners, but it also could be those military recruits.
00:06:38.560 --> 00:06:41.680
So those are some of the populations that we see it in.
00:06:41.759 --> 00:06:45.920
And another group that I found was very interesting was cyclists.
00:06:46.079 --> 00:06:58.879
And if you think about the loads on those knees, they uh reported about 35% prevalence in both in some kind of amateur cyclists who were involved in a competition, but also in elite cyclists.
00:06:58.959 --> 00:07:01.519
So it really does hit a lot of people.
00:07:02.000 --> 00:07:02.879
It was quite broad.
00:07:03.120 --> 00:07:08.079
And again, a common theme there you're talking about there essentially is varying types of overload.
00:07:08.240 --> 00:07:10.240
We're overloading that structure.
00:07:10.399 --> 00:07:14.160
And that brings about the question of what do we know what's going on?
00:07:14.399 --> 00:07:22.560
So actually anatomically, pathology-wise, what do we know about the actual structures that are involved and what's going on with those?
00:07:22.720 --> 00:07:23.920
Are we talking about cartilage?
00:07:24.000 --> 00:07:26.240
Are we talking about subchondrial structures?
00:07:26.399 --> 00:07:27.360
Do we even know?
00:07:27.600 --> 00:07:30.079
Claire, anything around those that we know at the moment?
00:07:30.399 --> 00:07:38.560
I think if we look at our younger patients, they're particularly interesting because often you'll get an MRI and or they have an MRI and it's pristine structurally.
00:07:38.959 --> 00:07:45.279
So I think we can say that invariably it's not to do with structural damage.
00:07:45.519 --> 00:07:53.120
And I try and purposely move the patients away from the concept in their mind from structural damage degradation.
00:07:53.279 --> 00:07:58.399
And I absolutely hate the term conjugation patelli because it's banded around.
00:07:58.720 --> 00:08:02.000
Patients Google, and then the next thing you think, oh my goodness, my knee's falling apart.
00:08:02.160 --> 00:08:05.439
And they presume that they're on this slippery slope.
00:08:05.600 --> 00:08:15.839
And actually, it's really useful, I think, to say to the patients, look, the cartilage is they knew it doesn't have any nerve and it's not that blocked-up cartilage that's the cause of your pain.
00:08:16.000 --> 00:08:18.480
And you can see them sitting there, and it's almost like a ticker tape.
00:08:18.639 --> 00:08:19.839
Why does my knee hurt?
00:08:20.079 --> 00:08:26.639
And then I purposely use the word pressure, and I have my fatal knee model with me, glued to me at all times.
00:08:26.720 --> 00:08:28.800
I get very cross if anyone goes off with it.
00:08:29.040 --> 00:08:36.159
And I will use it to demonstrate that asymmetrical loading, that concept of pressure on the subcontrol bone.
00:08:36.320 --> 00:08:42.799
Just as much as anything to try and help them make sense of it and try and get buy-in from the patients.
00:08:43.039 --> 00:08:44.320
And that's really important, isn't it?
00:08:44.480 --> 00:08:55.200
That I mean, know about patient understanding, coming away from that first appointment, having a really a good education around what's going on, because a lot of them I think are potentially around the knee as well.
00:08:55.279 --> 00:08:58.000
It it is that fear of the unknown as well, isn't it?
00:08:58.320 --> 00:09:06.960
Lisa, anything more to say around what we might know more around that's going on in that knee with our patelephemoral pain presentations?
00:09:07.279 --> 00:09:10.320
I just think that it really does vary so much.
00:09:10.480 --> 00:09:20.399
And several years ago, I used to see more in the literature about exactly which tissue was the culprit, if you will, for causing patients' patelephemoral pain.
00:09:20.559 --> 00:09:23.519
And I, you know, I don't see that as much in the literature.
00:09:23.600 --> 00:09:26.000
Now, I do have to say I'm not specifically looking for it.
00:09:26.320 --> 00:09:33.120
But some other tissues, in addition to totally agree with what Claire said, that healthy articular cartilage is a neural.
00:09:33.360 --> 00:09:37.279
And there can be some overload of the bone, some subchondral bone.
00:09:37.360 --> 00:09:39.440
I have seen some studies mentioning that.
00:09:39.600 --> 00:09:42.559
And also some of the soft tissues around the knee.
00:09:42.720 --> 00:09:44.879
There have been some studies looking at that too.
00:09:44.960 --> 00:09:47.039
But I just think it varies so much.
00:09:47.200 --> 00:09:52.720
And at the end of the day, we really want to do what we can to remove those excessive loads, right?
00:09:52.879 --> 00:09:54.159
No matter which tissue it is.
00:09:54.480 --> 00:10:02.559
And I suppose whilst removing those loads and adapting load, which we're going to talk about in short soon, is not then or removing the fear of load.
00:10:02.639 --> 00:10:10.080
And that's quite an important element to it when we're looking at rehab, isn't it, in terms of our understanding and reducing fear around the knee?
00:10:10.399 --> 00:10:12.879
I think the fear thing is incredibly important.
00:10:12.960 --> 00:10:19.360
And thankfully, finally, there is some really nice literature around this sort of over the last sort of five years or so.
00:10:19.440 --> 00:10:28.240
And Ben Smith really kicked that off in 2018 when he did a sort of really rich qualitative analysis of people with patelephromal pain.
00:10:28.320 --> 00:10:33.360
And that's been followed up with quite a lot of work now looking at kinese poem and catastrophizing.
00:10:33.600 --> 00:10:43.200
And the one study really comes to mind, Salhorst's work, and I think it was 21, looking at basically adolescents with patelophermal pain.
00:10:43.440 --> 00:11:00.639
Being showed an eight-minute video then measuring fear avoidance, catastrophizing, and TRE pain school immediately after, but also two weeks after, and showing that eight-minute viewing of education matters can really bring down that fear factor.
00:11:01.120 --> 00:11:13.600
Because otherwise, we're sending people off to do exercises, and Ben Smith's work has shown that most patients with patelochromal pain believe exercise to be harmful, the cause of their pain, create damage potentially.
00:11:13.840 --> 00:11:18.480
So bringing down that fear factor is really incredibly important, I think.
00:11:45.649 --> 00:11:47.009
Absolutely, yeah, definitely.
00:11:47.330 --> 00:11:53.889
Well, we're gonna talk about that, I think, the sort of a approach to these patients later when we talk about management, which is gonna be which can be really important.
00:11:54.129 --> 00:11:58.610
But I think we could move on now in terms of how patients present to us.
00:11:58.850 --> 00:12:04.769
So we're gonna see that this is a presentation that we're the clinicians watching this probably see an awful lot of.
00:12:04.850 --> 00:12:14.050
If you're working in an outpatient musculoskeletal department, sure many people are, whether that be private, NHS, or health insurance or whatever it might be, you're gonna see a lot of it.
00:12:14.210 --> 00:12:15.970
How might we see patients present?
00:12:16.050 --> 00:12:20.210
And I think we can split this maybe happily into subjective and objective assessments.
00:12:20.290 --> 00:12:25.090
We'll come on to how we might test this more objectively, but what would we see in subjectively?
00:12:25.170 --> 00:12:26.129
We've touched on this earlier.
00:12:26.370 --> 00:12:32.610
Lisa, what do we see in maybe in the literature or yourself clinically in our subjective assessment when someone comes in to see us?
00:12:33.009 --> 00:12:39.970
So subjectively, of course, it's going to vary with the patient according to their lifestyle, if you will.
00:12:40.290 --> 00:12:47.490
You could have the patient who is an active runner, an active adolescent, involved in different sports.
00:12:47.730 --> 00:12:50.769
And in most of their life, they're doing fine.
00:12:50.930 --> 00:12:55.409
And it's only when they try to perform their sport that they're having their problems, etc.
00:12:55.810 --> 00:13:03.409
That could then subjectively lead to the pain that's more intermittent and those kinds of things, and their disability, if you will.
00:13:03.570 --> 00:13:10.610
But then you also could have somebody who's relatively sedentary, could be somebody with an office job.
00:13:10.769 --> 00:13:17.810
I'm thinking about a patient that I had a few years ago that was an office worker, because of being sedentary was relatively weak.
00:13:17.889 --> 00:13:26.210
And so some very basic activities of daily living were the things that he was having problems with, just ascending, descending, stairs, et cetera.
00:13:26.370 --> 00:13:34.930
And then, of course, you could have other people who are at the other spectrum of the, or maybe at the older age or group that are starting to have some osteoarthritic changes.
00:13:35.090 --> 00:13:40.050
And they also are having problems with some basic ADLs, et cetera.
00:13:40.210 --> 00:13:47.090
So but all of them having pain centered around that patellophemoral part of the body.
00:13:47.409 --> 00:13:53.090
So it's again, yeah, that focal area, that point that we might see peripatello or retropatello, as we talked about before.
00:13:53.409 --> 00:13:59.490
And Claire, what might lead us to be more suspicious of that patellophemoral joint being involved?
00:13:59.730 --> 00:14:05.090
Lisa's talked about activities of daily living and uh and movements, other things that might tell us a little bit.
00:14:05.250 --> 00:14:10.930
Prick our ears to think that sounds much more patelephemoral than it does other areas of the knee.
00:14:11.250 --> 00:14:14.450
Yeah, so it's in essence a mechanical pain.
00:14:14.610 --> 00:14:25.009
Apart from sitting with your knee flex, which is an important question to ask, because if they have pay sat still with a knee flex, that again is very common in telephonal pain suffers.
00:14:25.330 --> 00:14:28.690
But apart from that, it tends to be quite on off.
00:14:29.009 --> 00:14:32.370
I go upstairs or downstairs, oh, it's a bit sore.
00:14:32.450 --> 00:14:35.009
And I often say, what happens when you get to the bottom and you walk off?
00:14:35.090 --> 00:14:38.370
And they might say it lingers a little bit, but in essence, it's gone again.
00:14:38.690 --> 00:14:44.690
You can highlight the positions, the movements in loaded flexion is the real hallmark.
00:14:44.930 --> 00:14:59.490
For example, walking on the flat would be highly unlikely to be patelephral pain, but walking downhill where you're bringing extra load onto the patella, you'd be more suspicious of patelephromal pain.
00:14:59.730 --> 00:15:05.409
So really looking at which activities and also I guess the absence of trauma.
00:15:05.889 --> 00:15:12.129
We can have other pathologies that drive an effusion that the effusion drives patellofhromoral pain.
00:15:12.290 --> 00:15:16.050
And it's important we are on our guard for pathologies that'd be picked up.
00:15:16.129 --> 00:15:23.330
But in essence, we're looking at a knee that it's just an insidious onset, which also is why the patient struggled to make sense of it.
00:15:23.649 --> 00:15:45.009
Yeah, and just to hop in on that, because it is that insidious onset of pain, and it is very mechanical, as you said, Claire, it's often quite a long time that the person has been experiencing this pain around the patella, by the time they get to see a physical therapist, we may or may not be that first provider that the person sees.
00:15:45.250 --> 00:15:55.649
So by the time we start to see them, I do completely agree that it's mechanical, that when they aren't sitting with their flexed knee, when they're resting, they're going to tend to feel better.
00:15:55.810 --> 00:16:02.610
But because it has become chronic pain, now it's going to start to have some of the changes within the central nervous system.
00:16:02.769 --> 00:16:06.129
And that nosoplastic kind of pain starts to develop.
00:16:06.290 --> 00:16:15.090
And that can almost be a spiral, if you will, leading to the kinesiophobia, to reduced physical activity and all of those kind of issues too.
00:16:15.409 --> 00:16:16.210
It's a really good point.
00:16:16.290 --> 00:16:18.690
I mean, the mean duration of Simpsons is long.
00:16:19.009 --> 00:16:19.250
Yes.
00:16:19.570 --> 00:16:23.170
And that, I suppose, is it leads into more questions from a patient.
00:16:23.250 --> 00:16:28.610
I know from from experience, patients often struggle when something doesn't get better as quickly as a cut on the finger.
00:16:28.930 --> 00:16:31.170
It doesn't then make sense as to why does this not get up?
00:16:31.570 --> 00:16:32.290
What's going wrong?
00:16:32.450 --> 00:16:35.649
Is this something more serious when it's something that's going on for longer?
00:16:35.810 --> 00:16:37.330
And do we see that with patients?
00:16:37.649 --> 00:16:38.210
I think so.
00:16:38.290 --> 00:16:41.250
And often their belief systems are really inaccurate.
00:16:41.409 --> 00:16:48.290
And that might be driven by things they've seen, they've heard, they might have had a mum that's had a knee replacement.
00:16:48.450 --> 00:16:59.409
Every patient's narrative is different, but often by the time they get to see you, there's a fair bit of unraveling to do around that inaccurate belief.
00:16:59.649 --> 00:17:01.889
And otherwise you're you're battling against that.
00:17:01.970 --> 00:17:07.250
And I think as I said before, Ben Smith's work just so beautifully encapsulated that.
00:17:07.730 --> 00:17:18.369
Really looking at what people thought it was about, what they thought would be the best interventions, rest, analgesia, and an ebrace was the consensus was going to be the best.
00:17:18.529 --> 00:17:28.049
So if you then waltzed in and say, right, let's do some exercises, and there's no education around that, you haven't helped the patient unravel that belief system and it's critical.
00:17:28.289 --> 00:17:29.889
Yeah, I completely agree with that.
00:17:30.049 --> 00:17:32.129
And you mentioned education, Claire.
00:17:32.209 --> 00:17:33.889
I mean, that's part of education, right?
00:17:34.049 --> 00:17:44.849
Is educating the patient that, okay, we understand that you are experiencing pain when you do certain activities, but that pain does not necessarily mean damage.
00:17:45.089 --> 00:17:56.849
And those are the kinds of things that they're worried about, that they're worried that if they do those exercises that we know is so important for them to do, if it hurts, they need to stop because they could be damaging themselves.
00:17:57.009 --> 00:18:00.049
That's that false belief that many of them have.
00:18:00.209 --> 00:18:03.889
And so we really need to educate them or de-educate them, if you will.
00:18:04.129 --> 00:18:07.250
I think that's so important for our patient management here.
00:18:07.490 --> 00:18:15.089
And I think perhaps in line with that, my Kreptis research, which was thematic analysis around semi-structured interviews.
00:18:15.329 --> 00:18:24.209
One of my questions was if you were doing your exercise your physio gave you, and whilst you were doing it, your knee made its noise, what would you do?
00:18:24.529 --> 00:18:27.409
Every single patient said, Oh, I wouldn't do it.
00:18:27.730 --> 00:18:32.689
And that was because they had the belief that the noise meant degradation and harm.
00:18:33.009 --> 00:18:35.649
So it's really important that we're on our toes.
00:18:35.730 --> 00:18:48.689
Otherwise, what we might be doing great assessment, got great exercises, and then the patient's gonna leave your room and not do it because that it's sore and they think that means damage, or it's crepitus, and they think that means damage.
00:18:48.769 --> 00:18:49.889
So it is very important.
00:18:50.209 --> 00:19:03.329
I'm gonna hop in there on a question that I think is really key, because it is Claire, having looked to that work and on some of your courses, that it you talk about the crepitus and that ex explaining to the patient that's not something to be fearful on how you go about that.
00:19:03.490 --> 00:19:07.490
I'd be really interested to know from both of you how do you go about that conversation?
00:19:07.569 --> 00:19:09.809
How do you explain to a patient what that actually is?
00:19:09.969 --> 00:19:12.609
Because I think I know a lot of patients will wonder, what is it then?
00:19:12.689 --> 00:19:18.289
If I'm not going to worry about that creaking, cracking, clicking, crunching noise in my knee, can you tell me what it is?
00:19:18.449 --> 00:19:20.529
So, how do you go about that conversation, Claire?
00:19:20.849 --> 00:19:26.209
The first thing, if they mention creptus, I often just say one question, and that is, what do you think it means?
00:19:26.369 --> 00:19:29.569
And if they say, Oh, I don't know, I don't think about it, fine.
00:19:29.809 --> 00:19:37.089
But if they say, Oh, look, my knee's falling apart or whatever, it opens the door to me thinking, okay, this is an inaccurate belief.
00:19:37.409 --> 00:19:41.730
So when I did my creptus research, yeah, it took me all over looking at noises.
00:19:41.889 --> 00:19:46.849
I ended up even looking at some of the engineering literature about noise or movement and what it meant.
00:19:46.929 --> 00:19:52.689
And in essence, I think the one that alarms patients the most is that sort of fine grating noise.
00:19:53.009 --> 00:20:02.929
And we can look at the engineering term slipstick, which basically means the noise that arises when fluid moves through an irregular surface.
00:20:03.169 --> 00:20:15.409
So, what I often say to patients is if I've got a nice thick pile carpet, and that's like your nice thick cartilage, so reinforcing that, but the top of the cart the top of the cartilage is just a bit fluffed up.
00:20:15.649 --> 00:20:22.449
If I pour water on that carpet and I do that, I'll get a sort of friction-y noise, and that's what's happening.
00:20:22.609 --> 00:20:33.169
It doesn't mean that the knee is falling apart, or you've got big holes in your cartilage, and we need to separate noise and pain because the noise may remain.
00:20:33.329 --> 00:20:41.969
Otherwise, you might get to get into good treatment and you think they're strong, their pain's gone, they leave your room and they still avoid the stairs because they still have the presence of crepitus.
00:20:42.849 --> 00:20:44.929
Lisa, how how do you go about that question?
00:20:45.089 --> 00:20:45.889
What are your thoughts?
00:20:45.969 --> 00:20:51.009
So, if anything from research to clinical experience, the noisy knee question.
00:20:51.490 --> 00:20:57.649
Well, the noisy knee, I mean that crepitus may or may not be present, but I completely agree with what Claire's saying.
00:20:57.809 --> 00:21:07.250
We can't necessarily base our interventions on that because that's kind of similar to maybe paresthesia in a lower extremity from a ridiculopathy.
00:21:07.409 --> 00:21:13.409
The person might experience centralization of their lower extremity pain, but the paresthesia stays for a while, right?
00:21:13.490 --> 00:21:16.849
So we can't just base our approach on that.
00:21:17.009 --> 00:21:31.089
And I love that description that you described, Claire, about the deep pile shag carpet, although I'm not looking forward to that coming back into popularity, that shag carpet, but that's such a great, uh great way to describe it.
00:21:31.169 --> 00:21:37.089
But honestly, I feel like patients have asked me more about the pain than the the crepitus.
00:21:37.329 --> 00:21:45.889
The older population that I've worked with who have some osteoarthritis of the knee involving the patal ephemeral compartment, they might ask me about it.
00:21:45.969 --> 00:21:54.369
And they come to me usually because I have a diagnosis of Neo A, and I can say that, you know, it might be having to do with that cartilage and that we won't worry about that so much.
00:21:54.449 --> 00:21:59.730
It'll be going more by their symptoms, any pain that they experience with different activities.
00:22:00.049 --> 00:22:00.689
Brilliant, brilliant.
00:22:00.849 --> 00:22:01.730
I thought I had to touch on that.
00:22:01.889 --> 00:22:05.409
One other thing I wanted to just look at is would we expect any swelling?
00:22:05.569 --> 00:22:10.449
And if we do find that the knee has swelling as well, does that tell us anything else?
00:22:10.609 --> 00:22:16.289
Claire, I think I've heard you mention before about swelling around the knee and patelephemoral pain and whether we should or shouldn't see it.
00:22:16.369 --> 00:22:17.969
And if we do see it, what does it mean?
00:22:18.289 --> 00:22:21.969
Well, I think there is different kinds of swelling, and I think that's the starting point here.
00:22:22.049 --> 00:22:24.129
Are we talking about a joint effusion?
00:22:24.289 --> 00:22:30.689
Are we talking about slightly puffy parapetella soft tissues, or are we talking about Hoffa's fat padema?
00:22:31.009 --> 00:22:34.849
So three quite distinct things that can indicate a different approach.
00:22:35.009 --> 00:22:41.009
So I think, particularly in a non-arthristic patella, if there's an effusion, I'm saying, why is there an effusion?
00:22:41.089 --> 00:22:47.089
And I would say, particularly if it's um an adolescent or a young adult, that should be treated as an as an urgent.
00:22:47.329 --> 00:22:49.490
Is there something more systemic going on?
00:22:49.649 --> 00:22:52.209
Is there a juvenile arthritis, a monomarthritis?
00:22:52.369 --> 00:22:56.049
Is there osteochondritis desiccins aggravating the synovium?
00:22:56.369 --> 00:22:57.809
Why is that effusion there?
00:22:57.969 --> 00:22:59.250
That's my starting point.
00:22:59.569 --> 00:23:06.289
If it's parapetella sort of puffiness, I think we often see that with the patients who perhaps are just subtly unstable.
00:23:06.369 --> 00:23:18.369
They're not dislocating, they might not even really be considered as a subluxa, but I think they've perhaps got a patella, maybe they've got a small patella sitting in a slightly shallow trochlea or a big tip of patella altar.
00:23:18.529 --> 00:23:23.409
And I think the patella just dings around and sort of pods the parapetella soft tissues.
00:23:23.490 --> 00:23:27.009
And I think you can see a little bit of puffiness, but it's not an effusion.
00:23:27.169 --> 00:23:30.609
And then obviously Hoffers is a whole different thing.
00:23:31.009 --> 00:23:32.209
Absolutely, definitely.
00:23:32.369 --> 00:23:33.649
We're not going to go down that road today.
00:23:33.730 --> 00:23:36.449
We definitely haven't got time as much as we'd like to.
00:23:36.529 --> 00:23:37.169
Yeah, definitely.
00:23:37.329 --> 00:23:41.730
Lisa, anything on on sort of effusion and swelling that you want to add to what Claire's said there?
00:23:42.129 --> 00:23:52.049
I think if we're thinking about just the typical patient with patellifemoral pain, there might be some on certain occasions because overuse is a big part of this.
00:23:52.209 --> 00:24:00.289
So if they have just had a long run the day before or something of that nature, they might have some mild effusion.
00:24:00.369 --> 00:24:07.009
And definitely if they have a problem with the patella impinging on the fat pad, that certainly could be swollen.
00:24:07.089 --> 00:24:09.009
But that would not be effusion, clearly.
00:24:09.169 --> 00:24:10.849
It might be present, but it might not.
00:24:11.089 --> 00:24:11.649
Fair enough.
00:24:11.809 --> 00:24:12.129
Excellent.
00:24:12.289 --> 00:24:12.529
Wonderful.
00:24:12.689 --> 00:24:15.649
So it leads nicely on to our objective assessment.
00:24:15.809 --> 00:24:20.689
So the bit that people often think pziers will jump to, what can we test?
00:24:20.849 --> 00:24:23.569
How can I make sure I've got the right diagnosis?
00:24:23.809 --> 00:24:28.049
What are your approaches to your objective assessments?
00:24:28.289 --> 00:24:36.769
Lisa, clinically or from research, what do we know about how good our objective assessment is and what might it include when we're talking about patelephemoral pain?
00:24:37.009 --> 00:24:47.969
So when I helped to work on the patelephemoral pain clinical practice guideline, we looked at some of the different diagnostic tests and, of course, their sensitivity and specificity.
00:24:48.369 --> 00:25:03.169
And so the test that we found for that had the best sensitivity for presence of patelephemoral pain was provocation of symptoms with squatting, which makes complete sense with the loading the knee in a flexed position.
00:25:03.490 --> 00:25:11.569
But as that could be painful for the person who has patellar tendinopathy, for knee osteoarthritis, for a lot of different conditions.
00:25:11.809 --> 00:25:14.849
So that's a great test to use early on.
00:25:14.929 --> 00:25:22.609
And if your patient does not have pain with squatting, patelli femoral pain becomes much less likely.
00:25:22.769 --> 00:25:23.089
Okay.
00:25:23.569 --> 00:25:32.209
And then the test that we found, and now this was a few years ago, and we're actually starting, we're preparing to do a revision of that clinical practice guideline.
00:25:32.289 --> 00:25:36.529
So stay tuned for a couple of years from now after we revise the literature.
00:25:36.769 --> 00:25:42.449
But the test at that time that had the highest specificity was the patellar tilt test.
00:25:42.689 --> 00:25:44.609
That is not a provocative test.
00:25:44.769 --> 00:25:51.490
That's a test to try to determine how tight essentially some of the lateral patellar retinacular structures are.
00:25:51.730 --> 00:25:56.049
And so that had the highest specificity, but it was not sensitive.
00:25:56.209 --> 00:26:01.250
So those were the tests and measures for whether or not the person might have patellophemoral pain.
00:26:01.329 --> 00:26:09.329
And of course, as we already mentioned, we need to be ruling out any other possible causes of their anterior knee pain, if you will.
00:26:09.649 --> 00:26:09.889
Okay.
00:26:10.129 --> 00:26:12.689
Claire, objective assessment 101.
00:26:12.769 --> 00:26:13.649
What are we looking for?
00:26:13.889 --> 00:26:33.409
I mean, I would be very much agreeing with what Lisa's saying then, but I perhaps the really mild patient that is perhaps saying, I've kind of got my pain out after a 12-mile mark of my run, for example, and they come in and then run for a week, you might need to do repeated single-leg squatting to just push that telephone or joint a bit hard.
00:26:33.490 --> 00:26:37.809
I mean, obviously, if you've got someone sort of coming in with a really irritable joint, we're not going to be doing that.
00:26:38.049 --> 00:26:45.809
But if you're thinking it does sound like sudden okay, but I can't quite produce it, that's where I would be going there, repeated single-leg squatting.
00:26:46.049 --> 00:26:56.209
And also, you know, I if somebody somebody is saying, look, it only comes and run a particularly it only comes on at five mile, ten mile point or whatever, I will get them to run to their appointment.
00:26:56.369 --> 00:27:07.089
And I know it might sound a bit extreme, but it's really interesting also from a risk factor point of view, assessing them at that point and assessing them fresh, it's often very different.
00:27:07.329 --> 00:27:15.569
And then it's easier to pick up whether it is definitely patelephemoral pain and also then look at, as I say, the sort of maybe the causative factors.
00:27:15.889 --> 00:27:19.889
We talked about squatting there from clinical guidelines and from what we know about the loading.
00:27:20.049 --> 00:27:21.809
Can we be specific about that squat though?
00:27:21.889 --> 00:27:34.689
So if I got someone to do a quarter squat to 30 degrees, am I going to see pain with a patelephemoral pain, or would I be more like to see it if I was to get them to squat deeper, past that 50 degrees, for instance, down into 90 degrees and further?
00:27:35.009 --> 00:27:39.649
Would that be something where I would see more and more likely to provoke those symptoms?
00:27:40.049 --> 00:27:44.369
Do we know more about the ranges of movement and the pressures that are put through that joint?
00:27:44.609 --> 00:27:48.769
I think we need to think about the biomechanics of the patelephemoral joint, James.
00:27:48.929 --> 00:28:05.329
So clearly, if people go back to their biomechanics education as an individual in the loaded condition, in a closed kinetic chain situation, as they go into a deeper squat, that is going to increase the loads on the patelephemoral compartment of the knee.
00:28:05.569 --> 00:28:09.329
Of course, some of that depends upon the position of the trunk, et cetera.
00:28:09.490 --> 00:28:20.529
But yes, I completely agree with what you're saying, Claire, with the patients who have the lower irritability, just a regular double leg squat is not going to necessarily provoke their symptoms.
00:28:20.689 --> 00:28:26.849
So we might want to progress to a single leg squat, maybe take it deeper, do more repetitions, et cetera.
00:28:27.089 --> 00:28:30.849
And yes, so biomechanically, the deeper squat more provocative.
00:28:30.929 --> 00:28:40.529
But then you're going to have your other patient who maybe is much more highly irritable, and just that a partial squat is going to provoke their symptoms.
00:28:40.849 --> 00:28:43.009
Anything more on ranges, Claire at all?
00:28:43.490 --> 00:28:53.009
I think just to sort of reiterate this point that the generally the deeper you're going into loaded flexion in a closed chain scenario, the bigger the loading pattern.
00:28:53.089 --> 00:28:55.490
It will be different in an open chain scenario.
00:28:55.569 --> 00:28:57.649
So we just need to make that distinction.
00:28:57.969 --> 00:29:08.609
But I think the patients will often be quite clever at just not even consciously, they'll be slightly offlating to the contralateral side, they'll stop just short of the tricky angles.
00:29:08.769 --> 00:29:12.689
So, you know, just be on your toes so that you don't think, oh, squat's okay.
00:29:12.769 --> 00:29:14.769
But actually, hang on, they're a bit asymmetrical.
00:29:14.849 --> 00:29:16.369
They've stopped at 60.
00:29:16.609 --> 00:29:19.649
What happens if we make that symmetrical and take it to 90?
00:29:19.889 --> 00:29:21.569
Oh, okay, now we can see it.
00:29:21.889 --> 00:29:22.369
Wonderful.
00:29:22.449 --> 00:29:28.769
So it really it is very much a subjective assessment, ruling out other pathologies.
00:29:28.849 --> 00:29:33.889
And would you say that a lot of the objective testing would be more about ruling out other things?
00:30:01.069 --> 00:30:07.549
Yes, but I wouldn't if there's absence of trauma, am I really going to spend a lot of time doing lots of ligament testing?
00:30:07.709 --> 00:30:08.989
We've only got so much time.
00:30:09.069 --> 00:30:18.829
I'd rather spend that time on looking at causation and muscle strength, muscle length, foot position, the things that we know may well be part or parcel of the driver.
00:30:18.989 --> 00:30:21.069
Yes, you can go to a tape box exercise.
00:30:21.149 --> 00:30:25.069
But if there's absolutely no history trauma, why am I testing their ACL?
00:30:25.389 --> 00:30:27.789
There's no clinical reasoning basis for that.
00:30:28.189 --> 00:30:38.909
Yeah, part of that ruling out has a lot to do with the patient's history, their past medical history, other possible comorbidities, activities that they're involved in.
00:30:38.989 --> 00:30:44.429
And as Claire said, this is when we're thinking patellophemoral pain, we're thinking non traumatic, right?
00:30:44.669 --> 00:30:47.149
They haven't just had a fall or things of that nature.
00:30:47.389 --> 00:30:53.549
And some of the other ways to rule these other conditions out are somewhat simple tests, such as.
00:30:53.949 --> 00:30:54.989
Palpation, right?
00:30:55.069 --> 00:30:58.349
And location of symptoms, thinking about patellar tendinopathy.
00:30:58.509 --> 00:31:02.189
And we could potentially do more sophisticated tests.
00:31:02.269 --> 00:31:07.869
And that's, I think, one of the fun parts about this is it's like a mystery sometimes, right?
00:31:08.109 --> 00:31:15.389
Trying to make sure that it is just patelliphemoral pain and not something else, or something else in combination with patelephemoral pain.
00:31:15.789 --> 00:31:16.509
Absolutely.
00:31:16.829 --> 00:31:21.069
Let us nicely really there into what sort of causes this.
00:31:21.389 --> 00:31:22.349
Why might this start?
00:31:22.429 --> 00:31:39.709
We talked about overload, but in your assessment, when you're looking at things like strength and range and things like that, what sort of things might we start to touch upon and see that we then might be able to forward into our plan and our management of these patients from our objective assessment?
00:31:39.869 --> 00:31:41.629
How might you prioritize those?
00:31:42.029 --> 00:31:46.749
It's relatively straightforward to determine that the patient has patellophemoral pain.
00:31:46.909 --> 00:31:51.709
But patients are so different, not just the activities that they're involved in in their lifestyle.
00:31:51.789 --> 00:31:54.669
They're, you know, are they a military recruit?
00:31:54.829 --> 00:31:56.749
Are they an adolescent athlete?
00:31:56.989 --> 00:31:58.989
Are they a sedentary individual?
00:31:59.149 --> 00:32:00.109
There's those things.
00:32:00.269 --> 00:32:04.749
But even besides that, some patients have weakness.
00:32:04.909 --> 00:32:09.469
I mean, that is as far as risk factors for developing patellophemoral pain.
00:32:09.629 --> 00:32:16.669
That's one of the risk factors that we have the best evidence for, that presence of weakness of the quadriceps muscle.
00:32:16.829 --> 00:32:23.549
And that's mostly been shown in some military recruits, which many of us are not working with military recruits.
00:32:23.709 --> 00:32:26.669
Many of us are working with adolescents or the general population.
00:32:26.829 --> 00:32:29.629
So we don't really have great evidence about that.
00:32:29.869 --> 00:32:35.069
So we need to see, you know, examine them and see are these the patients that have a lot of weakness?
00:32:35.229 --> 00:32:39.149
And if so, that's an impairment that I might be looking to work on.
00:32:39.389 --> 00:32:46.989
Other patients may have fairly adequate strength, but their movement patterns might be, you know, what we would call faulty.
00:32:47.149 --> 00:32:52.109
And Claire, you kind of alluded to that when you said, well, okay, they're squatting down, but how are they squatting?
00:32:52.269 --> 00:32:58.109
Are they kind of avoiding certain positions or are they collapsing into genuus, things of that nature?
00:32:58.269 --> 00:33:00.189
Once again, not everyone will do that.
00:33:00.349 --> 00:33:04.909
And then there's kind of a third group that's, well, do they have problems with their mobility?
00:33:05.149 --> 00:33:06.749
Are they hypermobile?
00:33:06.909 --> 00:33:13.149
You know, the patella is moving around excessively and they have some hypermobility the rest of their body, et cetera.
00:33:13.309 --> 00:33:14.669
Are they hypomobile?
00:33:14.829 --> 00:33:15.469
Are they tight?
00:33:15.629 --> 00:33:22.189
Maybe they have that positive patellar tilt test that I described, where they have mobility issues at their feet, et cetera.
00:33:22.349 --> 00:33:35.949
And then the kind of fourth group that I think about is maybe the person doesn't have any of those issues, but they've just done too much too soon, that loading and not allowing their body sufficient chance to recover from that.
00:33:36.189 --> 00:33:58.109
And one group that I think of in that situation are those young adults going into basic training in the military who might have had adequate strength, but not for the loads that are being applied to their bodies on a daily basis with all the marching and exercise and things of that nature and insufficient time to recover from those loads.
00:33:58.429 --> 00:33:58.749
Brilliant.
00:33:58.829 --> 00:33:58.989
Yeah.
00:33:59.149 --> 00:34:00.589
Claire, anything more on that?
00:34:00.909 --> 00:34:04.189
I guess there's a couple of things that I would perhaps add to that.
00:34:04.349 --> 00:34:10.670
In line with sort of hypomobility, I'd also be interested in restriction above and below.
00:34:10.909 --> 00:34:20.110
So if they haven't got any hip extension in take that into terminal stance in gate, they're going to have more knee flexion.
00:34:20.190 --> 00:34:26.190
So they're going to spend a bigger proportion of their gait cycle in knee flexion, higher patellophermal pressures.
00:34:26.349 --> 00:34:31.389
And similarly, if they have poor volume of dorsiflexion, we're going to see the same thing.
00:34:31.469 --> 00:34:40.190
We're going to have an early heel rising gait, tipping them into knee flexion, or they will excessively pronate to get over the foot.
00:34:40.350 --> 00:34:42.910
And I guess that then brings me to the final group.
00:34:43.070 --> 00:34:46.670
I ask every patient, do you notice your pain changes in different shoes?
00:34:46.829 --> 00:34:51.950
And some will say, No, absolutely saying barefoot slippers, get plops, trainers are no different.
00:34:52.269 --> 00:34:55.950
Others will say, Yeah, actually, there's a bit of a yes, my pain is different.
00:34:56.190 --> 00:34:59.550
And then I want to dig, what is it about that footwear?
00:34:59.710 --> 00:35:05.470
It might be someone with subchondral bone edema and it's just getting into a more cushioned shoe is better.
00:35:05.710 --> 00:35:17.789
But it might be someone in a flip-flop with no hindfoot support, and perhaps they're hypermobile, that that they're getting rear football as compensatory tubulation.
00:35:18.030 --> 00:35:27.949
So the foot in some patients, I think, is something that, and I say I the footwear, I think, is probably the best clue as to whether it's something to spend much time on.
00:35:28.349 --> 00:35:28.670
Okay.
00:35:29.070 --> 00:35:33.150
So a few things there, and we talked about risk factors in in in quadriceps.
00:35:33.309 --> 00:35:37.710
Lisa, just going back to that, does the research and tell us more any more about risk factors?
00:35:37.789 --> 00:35:42.190
Because obviously that does come into our assessment and what we might be looking for.
00:35:42.510 --> 00:35:42.750
Yeah.
00:35:42.990 --> 00:35:53.150
So most of the risk factors that have been looked at to date have mostly been biomechanical and kind of structural, if you will, anthropometric.
00:35:53.230 --> 00:36:06.510
And we really haven't looked a lot at the risk factors related to some of the psychological aspects, the fear avoidance beliefs, pain catastrophizing, some of those coping skills and things of that nature.
00:36:06.670 --> 00:36:19.550
And when we first started talking, Claire was talking about how we're getting more evidence about that, but we really don't have some good evidence about those factors related to risk for development of patelephemoral pain.
00:36:19.710 --> 00:36:28.030
And that those are some areas I'm I'm involved in a group right now from the International Patelephemoral Research Network that we've just been looking at.
00:36:28.269 --> 00:36:31.789
What's the evidence about the risk factors and where do we have gaps?
00:36:31.949 --> 00:36:43.470
And some of the gaps that need to be looked at more closely are definitely those psychological factors, other behavioral factors, pain coping, and those kinds of things, as well as looking at specific subgroups.
00:36:43.630 --> 00:36:49.710
We really haven't looked much at the general population, even though that's a big area.
00:36:49.949 --> 00:36:57.710
As I already mentioned, 23% of people in that general population are at risk every year for development of pataliphemoral pain.
00:36:57.789 --> 00:37:08.190
And more of the studies on risk factors have been done in somewhat controlled populations, military populations, individuals who all are just starting basic military training.
00:37:08.429 --> 00:37:10.030
Those have been some of the studies.
00:37:10.190 --> 00:37:17.389
Some of the other studies have looked at people all enrolled in a couch to 5K program, if you will, a start-to-run program.
00:37:17.550 --> 00:37:22.670
And I think it's probably a little bit easier to control the factors in those populations.
00:37:22.909 --> 00:37:37.789
But, you know, if I take the evidence from that military population for risk factors, how does that really transfer to my adolescent population or my general relatively sedentary population?
00:37:37.949 --> 00:37:45.070
So we really have a lot more work that needs to be done, particularly in those psychosocial and behavioral kind of areas.
00:37:45.470 --> 00:37:49.949
And what about risk factors to prolonged time to get better?
00:37:50.110 --> 00:37:57.230
Do we know more about what might push someone to be more chronic, someone who might take the longer to get better or not at all?
00:37:57.630 --> 00:38:01.710
So for the prognosis, that's another group is looking closely at that.
00:38:01.789 --> 00:38:04.429
So you folks will have to keep stay tuned for that.
00:38:04.670 --> 00:38:08.190
Some of these articles are actually under review right now by a journal.
00:38:08.429 --> 00:38:23.150
But for the prognosis, we definitely know that people who have a longer duration of symptoms when they start their treatment program, they are at risk for a poor prognosis and also greater self-reported disability.
00:38:23.389 --> 00:38:27.710
That's from an article that was done by Ninka Langhorst several years ago.
00:38:27.869 --> 00:38:35.710
And I believe that group that's investigating prognosis has also found that those psychosocial areas are really understudied, if you will.
00:38:35.869 --> 00:38:38.110
And that's another big area for that.
00:38:38.510 --> 00:38:38.990
Brilliant.
00:38:39.309 --> 00:38:41.869
Claire, any more on that from research or from experience?
00:38:42.429 --> 00:38:45.550
Anecdotally from the clinic setting that we fits.
00:38:45.710 --> 00:38:52.750
Those patients with poor self-efficacy, no sense of controllability about it, maybe inaccurate beliefs.
00:38:53.070 --> 00:38:57.949
They just often have engaged well with their program.
00:38:58.590 --> 00:39:00.750
And you know, you can have the best treatment in the world.
00:39:00.829 --> 00:39:07.710
But if someone doesn't do it or doesn't do it to the intensity take strengthening, you know, we want to strengthen a muscle and we have to overload it.
00:39:07.949 --> 00:39:15.230
So a few very light and fluffy exercises here and there, you know, is actually very unlikely to build meaningful strength gains.
00:39:15.389 --> 00:39:23.389
So it's yeah, anecdotally, I think those patients that have fearful, inaccurate beliefs are absolutely the ones with the worst prognosis.
00:39:23.630 --> 00:39:25.230
And we need to investigate that.
00:39:25.470 --> 00:39:25.710
Yeah.
00:39:26.110 --> 00:39:26.670
Yeah, definitely.
00:39:26.750 --> 00:39:37.710
And it links back to what we said right at the beginning in terms of how education and understanding is so important and leads to a lovely segue in into what we're going to talk about next, which is management in this population.
00:39:37.789 --> 00:39:45.309
And and this is a big area because obviously the kind of the main point here is our management is going to be different for very different patient populations.
00:39:45.389 --> 00:39:57.150
So I suppose what would be really good to come out of this is your tips and things that you found that have worked well, that things that you would look to do with that previously you found work well with patients for both of you.
00:39:57.230 --> 00:40:03.470
And then around the research, what do we know as a consensus guideline on how we should be managing these patients?
00:40:03.630 --> 00:40:06.190
Claire, we'll we'll start with you in terms of management.
00:40:06.269 --> 00:40:08.670
And I know I'm throwing you a really hard task here.
00:40:08.909 --> 00:40:13.710
Yeah, well, except how long these are streaming, but let's just chip off load.
00:40:13.869 --> 00:40:18.590
It's very easy to say yes, it's really relevant, but actually, how are we going to impact on that?
00:40:18.750 --> 00:40:29.869
And what I do is I get I have a grid that I've made that I have, I get the patients to fill it in, particularly with my adolescents, and it says before school, morning, lunchtime, PM, after school, weekend.
00:40:30.030 --> 00:40:33.630
And it's people often have the impression it's the elite kids, and it's not.
00:40:33.710 --> 00:40:35.710
It's often just the very sporty kids.
00:40:35.869 --> 00:40:46.510
So they might be playing school hockey, might be playing hockey for a local club, maybe do a tennis lesson on a Saturday, Sunday, a part run on the Saturday, and they do Kit Fit on lunchtime just because they like it.
00:40:46.670 --> 00:40:52.349
And then when you actually look at the accumulative load, it's massive.
00:40:52.510 --> 00:41:02.429
And in terms of management, I say often we'll say, look, we don't want this to get so sore that it forces your hand and you can't then do anything, any sport for a while.
00:41:02.590 --> 00:41:03.789
That would be a real shame.
00:41:03.949 --> 00:41:07.150
So let's look at can we get a rest day?
00:41:07.389 --> 00:41:14.829
Can we actually change your position on the netball court temporarily so that you still play, but you're not herring around the court quite so much?
00:41:14.990 --> 00:41:17.550
What are the ways in which we can manage that load?
00:41:17.630 --> 00:41:31.949
And just having it mapped out, I find, particularly as I say with the kids, with hopefully mum or dad, if you can get them on board as well, you know, that which is obviously another challenge, that can be just a really useful way of actually managing it.
00:41:32.030 --> 00:41:34.429
Because you can't just say, don't do as much sport.
00:41:34.670 --> 00:41:37.630
That's very unlikely to bring about meaningful change.
00:41:37.789 --> 00:41:40.510
So starting with a load, that would be my top tip.
00:41:40.829 --> 00:41:51.789
And on that, I think, Clara, remember from the masterclass, I think it was you did with the physio network, was there's some quite interesting research that showed actually a really vast improvement in just load management.
00:41:51.869 --> 00:41:52.190
Am I right?
00:41:58.349 --> 00:42:02.590
In essence, he deloaded to then incrementally reload.
00:42:02.829 --> 00:42:04.909
So that's what I'm talking about.
00:42:05.150 --> 00:42:17.309
I don't want to stop them exercising, but just bring it back a bit and then layer it back in incrementally, making sure that they're a bit more aware of not just rest days, but also with the kids.
00:42:17.470 --> 00:42:25.389
I think often what it goes wrong because they have the long holidays and some of them don't do anything, and then they go straight back into full loading as well.
00:42:25.550 --> 00:42:29.630
So trying to avoid that robust graph of load as well.
00:42:30.030 --> 00:42:31.789
Change of school as well, I suppose, is it?
00:42:31.869 --> 00:42:41.389
You know, when you go in from primary school or and to secondary school, that sudden change in expectations of availability of school sports and school activities.
00:42:41.789 --> 00:42:45.150
And Lisa, around load management, a big part of this.
00:42:45.389 --> 00:42:50.750
Anything you can add on that in terms of what we've found researched clinically around load management?
00:42:51.070 --> 00:43:09.710
So I think load management is the part with the intervention that we really need to have more evidence about because there is a lot of research saying that what we call knee-targeted interventions, where we're really talking about strengthening the quadriceps muscle, that has really been shown to be helpful for most people.
00:43:10.269 --> 00:43:13.309
But we don't really know a lot about the dosing of that.
00:43:13.470 --> 00:43:16.030
And of course, that could vary depending upon the person.
00:43:16.269 --> 00:43:23.070
The other area is many people require some hip-targeted strengthening exercises.
00:43:23.230 --> 00:43:25.630
Not everyone, but many people will.
00:43:25.869 --> 00:43:38.990
And I think for some of the people who maybe have some of that excessive irritability of the knee, trying to tolerate some of the knee-targeted exercise, they might benefit from let's kind of back off a little bit from that right now.
00:43:39.150 --> 00:43:42.829
And we're going to focus maybe on some impairments of hip muscle strength.
00:43:42.909 --> 00:43:54.590
And also, I find some of the patellar taping with the rigid tape, such as the McConnell type of method, to be very helpful for some of my patients to kind of unload some of the tissues.
00:43:54.670 --> 00:43:59.949
And then maybe they can tolerate some of that quadriceps strengthening if I use that.
00:44:00.190 --> 00:44:00.829
Absolutely.
00:44:00.990 --> 00:44:04.670
And I know tape is controversial and the literature is a bit all over the place.
00:44:04.750 --> 00:44:11.710
But my view is if it changes the pain, if it decreases the pain, gives you a window in, absolutely use tape.
00:44:11.869 --> 00:44:17.230
Not for everyone at all, but for some patients it can be, and again, I would use the rigid tape too.
00:44:17.389 --> 00:44:17.550
Yeah.
00:44:17.710 --> 00:44:18.030
Yeah.
00:44:18.190 --> 00:44:20.750
Because you want to get that patient buy-in, right?
00:44:20.909 --> 00:44:30.269
If I can do something with that patient and help them take away their pain or at least reduce it quite a bit, and now I can get them to be doing the exercises.
00:44:30.429 --> 00:44:36.909
And especially for the taping that, you know, according to the McConnell method, I can teach my patient to tape their own knee.
00:44:37.070 --> 00:44:41.710
And that way they can use it and start to kind of wean off from it and things of that nature.
00:44:41.949 --> 00:44:42.909
I agree with you, Claire.
00:44:42.990 --> 00:44:48.030
It is a little bit controversial, partly because there's so many different ways to tape it.
00:44:48.190 --> 00:44:52.510
So that makes it really challenging for exercise for research studies, right?
00:44:52.590 --> 00:44:56.269
Where we want to try to do things systematically and the same for everyone.
00:44:56.510 --> 00:45:01.230
I think just adding in about this concept of buy-in, it's very interesting running a second opinion service.
00:45:01.309 --> 00:45:03.710
So everyone I see has had failed treatment.
00:45:03.949 --> 00:45:06.670
And there's two things that come up again and again.
00:45:06.909 --> 00:45:09.389
One is I say to them, what was the gist of the treatment?
00:45:09.550 --> 00:45:12.030
And they'll say, exercises.
00:45:12.190 --> 00:45:14.909
And then I say, What were you trying to achieve with the exercises?
00:45:14.990 --> 00:45:18.190
And I'm not expecting to say in a range of gluteus medius or whatever.
00:45:18.269 --> 00:45:22.670
I'm expecting just a bit stronger up here or a bit flexible down there, something like that.
00:45:22.829 --> 00:45:25.309
And very often they have no idea.
00:45:25.470 --> 00:45:28.110
They've just been passively doing these exercises.
00:45:28.190 --> 00:45:29.150
So no buy-in.
00:45:29.309 --> 00:45:37.869
And then the other thing I see repeatedly is I was told I need to get stronger, and I was given these lunges and squats, and it just made me really sore and I've stopped.
00:45:38.269 --> 00:45:47.470
Not only is it probably not going to be affected as a strength modality, but you well and surely are going to lose your patient's confidence if you give them a painful treatment that makes them worse.
00:45:47.789 --> 00:45:56.990
Or if we give them too many exercises, we can't just hand them a paper with six exercises that you want them to do twice a day or three times.
00:45:57.070 --> 00:45:58.590
You know, they're just not going to do it.
00:45:58.909 --> 00:46:00.829
They often get the exercise out.
00:46:00.990 --> 00:46:02.510
There's like a sort of scroll.
00:46:02.750 --> 00:46:12.429
And actually, again, if we're trying to be evidence-based, if we look at the literature on adherence, if you're going to go above three exercises, you've got to have a highly motivated patient on board to do that.
00:46:12.670 --> 00:46:20.190
So we can't forget to tell patients to stop doing certain exercises if we progress them to another one.
00:46:20.590 --> 00:46:26.429
You see that patient that comes in with, I'm doing these, oh, and I'm still doing the other ones I was set right at the beginning, right through.
00:46:26.590 --> 00:46:26.750
Yeah.
00:46:26.990 --> 00:46:32.829
So understanding why you are doing or getting the patient or asking the patient to do what they're doing and having their buy-in.
00:46:33.230 --> 00:46:40.349
I often say to patients, I'd like you at the end of this to have as good as an understanding as I do about what's going on and why we're doing what we're doing.
00:46:40.510 --> 00:46:43.389
Because I think that we owe it to the patients to have that understanding.
00:46:43.630 --> 00:46:46.190
I'm aware of time, but I really want to carry on with this a little bit.
00:46:46.349 --> 00:46:56.590
So, in terms of loading, some might say that's going to be really hard because if we want to strengthen quadriceps, we know that a lot of that work is going to be done with a loaded knee.
00:46:56.750 --> 00:47:08.829
What are your tips and tricks around how you can get over that or get around that pain element of patellifemoral pain when we want to load those quads?
00:47:08.990 --> 00:47:10.030
How can we go about that?
00:47:10.190 --> 00:47:13.710
Thinking about dosage for strength and how we need to make it challenging.
00:47:13.949 --> 00:47:17.630
I think this goes back to our understanding of biomechanics and angles.
00:47:17.789 --> 00:47:32.670
So if, for example, we do want to target the quads, then we could say, okay, well, I might get you if they've got say gym access, I might say, well, we know that open chain is kind of on the telephone or joint 90 to 45.
00:47:32.829 --> 00:47:41.710
So I might get you working through that range open chain, and then I might get you working, say, zero to 50 closed chain.
00:47:41.949 --> 00:47:57.070
Now they might say oh it feels a bit easy, but I say, well, I would prefer you doing zero to 50 with some isometric hold and a barbell than zero to 90 body weight banging up and down and upsetting with weight.
00:47:57.230 --> 00:47:59.949
So angles, really, really critical.
00:48:00.190 --> 00:48:04.190
And tape, as we mentioned, often gives you a really nice weigh-in.
00:48:04.590 --> 00:48:15.389
And I guess my final thing is if I really am just banging my head against the brick wall, I think I know they need to get stronger, but I just am struggling here, I would use blood flow restriction training as well.
00:48:16.269 --> 00:48:18.990
I'm so glad you mentioned that blood flow restriction.
00:48:19.070 --> 00:48:20.590
I was exactly thinking of that.
00:48:20.750 --> 00:48:28.670
I mean, I know that, you know, could be expensive, could be something that's not necessarily available to people, but I have seen some good results.
00:48:28.750 --> 00:48:43.309
I'm thinking of someone I used it with who actually was having trouble regaining strength after a knee replacement surgery, but you know, just not able to exercise to the intensity that they needed to achieve that gain in strength, if you will.
00:48:43.550 --> 00:48:45.150
So that can be very helpful.
00:48:45.309 --> 00:48:51.710
Yes, I mean, alternating positions to try to mechanically reduce the load on the patellothermal compartment.
00:48:51.869 --> 00:49:07.389
And then the other thing that I have done, some of my older patients with patellofharmal osteoarthritis is wait a little bit with the quad strengthening and start with the strengthening around the hip, the posterior lateral muscles of the hip and the core.
00:49:07.630 --> 00:49:30.269
Many of them have quite a bit of abdominal weakness, and I can get them starting to strengthen those areas, and that hopefully can improve their movement patterns and you know, get them used to doing exercises and knowing what that sensation is when you just load a muscle and maybe have some soreness from that, but it's not the pain that they have from their patelephemoral pain.
00:49:30.510 --> 00:49:30.829
Brilliant.
00:49:31.070 --> 00:49:46.349
I've just looked at the time and we are massively over time, but to finish off, what I want you to think of now is the listeners listen to this, some of them may be students, new graduates, experienced clinicians who see patellifemoral pain on a regular basis.
00:49:46.510 --> 00:49:51.710
But to all of those people, what would be your takeaway that you'd like them to get from this?
00:49:52.030 --> 00:49:54.909
Things that you've seen that people you think could improve.
00:49:55.070 --> 00:49:59.470
Claire, you mentioned your second opinion work, Lisa, particularly around the research.
00:49:59.630 --> 00:50:07.869
What are some of the things, the key things you'd like people listening to this to really take away and utilize in their clinics and practice tomorrow morning?
00:50:08.349 --> 00:50:29.309
I suppose for me it would be, you know, I think dizzy is like to do, don't we like to feel, like to move, but I think listen, listen to your patient's narrative, listen to the fact that they are running for their mental health, or listen to the fact that they've had pain on the other leg and it actually took a year to go.
00:50:29.389 --> 00:50:32.670
So that's their expectation for this, or whatever it may be.
00:50:33.230 --> 00:50:38.990
Listen, because in response to that, you can make your education really bespoke.
00:50:39.070 --> 00:50:48.590
And then it is meaningful, it lands with a patient, they know you've listened to them, and again, then you're more likely to move forward with that patient biome.
00:50:48.990 --> 00:50:50.510
I would completely agree with that.
00:50:50.590 --> 00:50:53.470
You know, just to keep in mind that every person is unique.
00:50:53.630 --> 00:50:59.389
We've been talking about patelephemoral pain, but that's part of a person's body, right?
00:50:59.550 --> 00:51:00.349
Their knee.
00:51:00.510 --> 00:51:03.070
You're treating the patient, you're treating the person.
00:51:03.309 --> 00:51:09.869
So when you're listening to them, keep in mind that not everyone is a runner trying to run further.
00:51:10.110 --> 00:51:13.949
People have different lifestyles and those types of things.
00:51:14.110 --> 00:51:19.949
And also not everyone is necessarily weak in their quadriceps or some other factor.
00:51:20.030 --> 00:51:22.030
So there could be other things going on.
00:51:22.110 --> 00:51:31.150
So don't just fall into the trap of giving everyone quad-strengthening exercises, and maybe you're also doing gluten mead strengthening exercises.
00:51:31.389 --> 00:51:37.230
We really need to think holistically about that person, who they are, what they're trying to get back to doing.
00:51:37.550 --> 00:51:37.949
Brilliant.
00:51:38.030 --> 00:51:39.389
What a wonderful way to finish.
00:51:39.550 --> 00:51:41.150
Treat the person, not the pathology.
00:51:41.230 --> 00:51:41.389
Yes.
00:51:41.710 --> 00:51:42.429
Not the presentation.
00:51:42.990 --> 00:51:45.470
Claire, Lisa, thank you so much for this.
00:51:45.550 --> 00:51:47.150
Um, it's really sad to have to stop.
00:51:47.230 --> 00:51:50.590
I think we could have carried on this for a vast amount of time longer.
00:51:50.750 --> 00:51:56.030
But I really appreciate both of you for the time you've given us and our listeners, I'm sure, would have taken an awful lot from this.
00:51:56.190 --> 00:52:07.150
We'll make sure we've got links of how people can find more about both of you and the work that you both do so very well for us clinicians, of which is very much appreciated by everyone listening and certainly for myself.
00:52:07.309 --> 00:52:11.949
But on behalf of Pizza Network and everyone listening, thank you both very much for your time.
