The medial collateral ligament (MCL) is one of the four major ligaments of the knee. It is a broad, flat, membranous band, situated slightly posterior (back) on the medial (inner) side of the knee joint. It resists forces that would push the knee medially, which would otherwise produce valgus deformity, commonly referred to as "knock-knee." MCL tears often occur from soccer, skiing, or football and involve the joint being bent to the side, tearing the ligament that exists just inside the soft tissue of the knee. The MCL usually tears partially and is often graded as a Grade 1, 2 or 3 type of tear. Fortunately, the MCL has a very good blood supply. By protecting and rehabilitating it early with gentle range-of-motion exercises, soft tissue massage, and specific strengthening exercises, the tissue can be induced to heal in a relatively normal pattern with collagen fibers aligned along the normal pathway of the original MCL. Surgical repair of the MCL, in our opinion, is infrequently needed because the MCL will often heal. Occasionally, MCL injuries lead to chronic instability and in those cases we rebuild the MCL typically using an allograft or donor tissue to augment the suture repair of the ligament itself.
Knees do not necessarily wear out evenly, sometimes one part of the knee is perfectly fine while another part is completely destroyed. If only part of the knee joint is worn out, why replace all of it?
Data everywhere, and nowhere to hide. In the bad old days, you got injured, and you didn’t tell anyone. You usually recovered. Lived to play another day. Until you couldn’t. Today, you get injured; you could be monitored, measured, uploaded and reported to everyone. You might not be allowed to play. You are “protected”, maybe even blacklisted. Which scenario is better?
