Advice

The medial collateral ligament (MCL) ligament is a ligament on the inside of the knee that connects the thigh bone to the shin bone in the lower leg. It provides stability for inward movements of the knee. The MCL is injured by direct blows to the outside of the knee that push it inward, rapid cutting and change of direction movements, and landing awkwardly when jumping.

Knee ligament injuries can produce the following symptoms:

1. Feeling or hearing a pop at the time of injury
2. Giving way or experiencing a sense of knee instability
3. Rapid onset of swelling within the first several hours
4. Intense pain at the time of injury
5. Inability to weight bear
