Definition: The medial collateral ligament (MCL) is one of four ligaments critical to the stability of the knee joint. A ligament is made of tough fibrous material and functions to control excessive motion by limiting joint mobility.
The MCL prevents knee injury by stabilizing the joint and preventing the knee from buckling inwards. The ligament attaches to the femur (thigh bone) and the tibia (shin bone) and runs across the inside (medial aspect) of the knee.
