Medial collateral ligament is one of the stabilizers of the knee which prevents the opening up when a outside-in force is applied. The Ligament has a role in initial bending of the knee also.

Usually injured in violent contact or collision sports or in traumatic accidents along with other ligaments. Usually this injury can be treated conservatively. But in cases with a complete disruption or tear, it may require a surgical intervention. Patients are advised to use a knee brace for at least 6 weeks and only isometric quadriceps exercises.

The diagnosis needs a clinico-radiological correlation and so does the decision of plan of treatment. In case where MCL is associated with other ligamentous injuries, it usually requires surgical intervention along with other associated ligament reconstruction.
