BU BÖLÜM HAKKINDA
When does a knee cartilage defect need more than a clean-up, and how do you decide on the best repair? On this episode of BackTable Bone & Sports, Dr. Larry Balle welcomes orthopedic sports surgeon Dr. Sachin Allahabadi for a practical tour of cartilage restoration. Together they explain what articular cartilage is, why it rarely heals on its own, and how to distinguish focal chondral defects from diffuse arthritis. The discussion covers the full spectrum of treatment, from chondroplasty and microfracture to cell-based restoration, osteochondral autograft, and allograft transplantation.

More about this episode
Dr. Allahabadi discusses how to select the right patients for different cartilage procedures, including how defect size, alignment, meniscus status, and ligament stability all factor into the decision. They review advances in cartilage repair techniques, the process of storing and matching fresh donor tissue, and the use of bone marrow aspirate concentrate to promote graft integration. The conversation also addresses the durability of allografts in real-world practice, setting realistic expectations with patients, the importance of referral to high-volume surgeons, and why thoughtful clinical decision-making is often more challenging than the procedure itself.
