Knee injury - medial collateral ligament (MCL); MCL injuryDefinition Return to top
MCL injury is a stretch, partial tear, or complete tear of the medial collateral ligament (MCL) of the knee. (The term "medial" means the ligament is on the inside of the knee.)Considerations Return to top
During physical eaxmination with a medial collateral ligament test, the doctor can detect looseness of the ligament. This test involves bending the knee to 25 degrees and putting pressure on the outside surface of the knee.Causes Return to top
The medial collateral ligament (MCL) is a ligament extending from the upper-inside surface of the tibia (the shin bone) to the bottom-inside surface of the femur (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, resulting in stress on the inside of the knee joint (valgus stress).
It is often injured at the same time as an anterior cruciate ligament (ACL) injury.
Symptoms Return to top
First Aid Return to top
Initial treatment of an MCL injury includes ice to the area, elevation of the joint (above the level of the heart), non-steroidal anti-inflammatory drugs (NSAIDS), and limited physical activity until the pain and swelling subside.
After an initial period of immobilization (usually with a knee brace), gradual mobilization of the knee with strengthening and stretching should be performed. Physical therapy may be helpful to help regain knee and leg strength.
Surgery for isolated tears of the MCL is not usually performed.
