Definition/Description. A medial collateral ligament (MCL) injury is a stretch, partial tear, or complete tear of the ligament on the inside of the knee. It is one of the most common knee injuries and results mostly from a valgus force on the knee [1] [2].
A medial collateral ligament (MCL) knee injury is a traumatic knee injury that typically occurs as a result of a sudden valgus force to the lateral aspect of the knee. Diagnosis can be suspected with increased valgus laxity on physical exam but requires MRI for confirmation.
MCL injuries are usually caused by getting struck in your knee or by bending or twisting the joint too forcefully, causing the ligament to stretch and tear. Wear and tear of the ligament over time through repeated stress and pressure, such as lifting heavy objects, can also cause injury to the MCL.
The collateral ligaments -- medial (MCL) and lateral (LCL) -- are found on the sides of your knee. Injuries to the collateral ligaments are usually caused by a force that pushes the knee sideways. These are often contact injuries, but not always.
