Knee Plica Surgeries

The Regenexx blog has a very interesting article on knee plica surgeries. Knee plicas refer to collisions between the knee cap (patella) and the nearby synovial membrane, which surrounds the joint. The pinching of the synovial membrane irritates it and generates swelling and pain. The common surgical procedure to treat knee plica is to extirpate the irritated synovial membrane. Centeno points out that this portion of the synovial membrane houses a robust stem cell population that helps heal knee problems. Therefore, this procedure might not be the best choice for knee plica. Centeno suggests that the knee is not aligned properly and that realignment of the knee cap could solve the problem without surgery. Read his blog post here and see what you think.
