Cartilage is a unique tissue in the body. It has less blood supply than other structures and that makes healing on its own very difficult. There are several techniques to restore cartilage function. Weight management, gentle exercises, avoiding impact all help in the long run. Other options include injections such as viscosupplementation, cortisone, stem cells and platelet rich plasma injections. Physical therapy for muscle balance, range of motion and strengthening is one of the main stays of treatment. Finally, surgical options such as cartilage allograft, mosaicplasty, cartilage allograft transfer help in select patients. Osteotomies (where you cut and realign the bone) is more invasive but does have good 5 to 10 year results in the right patient. Dr Kalra is uniquely trained in several of these procedures and has been performing them for over a decade.
