How to treat a medial collateral ligament injury

Fact Checked

A medial collateral ligament injury is a sprain or tear on the medial collateral ligament. It is a bundle of tissue on the interior of the knee and links the thigh bone to the lower leg bone. It also prevents the joint from over-extending inward and for stability and rotation.

The medial collateral ligament can be injured when performing activities that involve twisting, bending or a sudden change of direction such as playing soccer or football when the outer area of the knee is struck. It can also happen while skiing and other sports that requires a lot of stationary and active movements, jumping as well as weaving. These injuries can be classified into grade 1 injury which is the least severe. The ligaments are only stretched but not torn. In grade 2 injuries, the ligaments are partially torn and cause instability of the knee joint while grade 3 is the most severe type where the ligament is completely torn and there is joint instability.
