Medial collateral ligament (MCL) injury is a stretch, partial tear, or complete tear of the ligament on the inside of the knee.

Knee injury - medial collateral ligament (MCL); MCL injury

The medial collateral ligament (MCL) extends from the upper-inside surface of the shin bone to the bottom-inside surface of the thigh bone. The ligament stabilizes the joint on the inside of the knee.

The MCL is usually injured by pressure placed on the knee joint from the outside.

It is often injured at the same time as an anterior cruciate ligament (ACL) injury.
