    Injury to the medial collateral ligament (MCL) often occurs after an impact to the outside of the knee when the knee is slightly bent. The MCL becomes stretched and if the force is great enough, some or even all of the fibers will tear. The MCL is often injured at the same time as an anterior cruciate ligament (ACL). Participants in sports like soccer, football, lacrosse and basketball are most likely to injure their MCL.
