ÜBER DIESE EPISODE
In this episode of the OrthoInfo podcast, adult reconstruction surgeons Matthew Deren, MD, FAAOS, and Nicholas Scarcella, MD, FAAOS, help patients understand what to expect if you have knee replacement surgery — from what makes someone a good candidate for the procedure to surgical preparation to what happens when an implant fails.
Drs. Deren and Scarcella offer an honest look at the recovery process, setting realistic expectations about the challenges of the first two months, the role of physical therapy, how the new knee may feel and function, and the long road back to the activities patients love. They also discuss robotic-assisted knee replacement, which has been gaining popularity in recent years but may not be right for every patient. And they emphasize the importance of trying to manage arthritis symptoms without surgery as long as the knee isn’t causing too many problems. As Dr. Deren put it: “If people can have a lot of knee arthritis and be functioning very well, I tell them, ‘keep your own parts as long as you can.’”
