Injury to the medial collateral ligament of the right knee is a relatively common disease, mainly because the knee joint is subjected to violence from the outside to the inside, so the medial collateral ligament is subjected to violent tension, and in severe cases, even rupture and tear can be formed. When the injury to the medial collateral ligament of the right knee is relatively mild, conservative treatment can be used, with a cast immobilized for four weeks, and after removing the cast, you can do functional exercises for the joint. If the injury to the right knee medial collateral ligament is severe enough to reach the level of rupture, surgical treatment is required for healing, and anchors, pins or absorbable screws can be used as internal fixation.
