The MCL or medial collateral ligament is one of the four ligaments of the knee. The term medial is derived from the Latin term medialis or middle.
The ligament is on the inside of the knee and connects the bottom of the thigh bone (femur) to the top of the shin bone (tibia).
The MCL is commonly injured from a blow to the outside of the knee.
MCL injuries should initially be treated in the same manner as any other acute ligament injury — follow the P.I.E.R. principle (Pressure, Ice Elevation, Restriction).
It’s important to refer the athlete to a medical professional with experience in sport injuries to rule out any damage or fractures to other areas.
A knee brace will control the movement and help the ligament heal in a shortened position. The Anterior Cruciate Ligament (ACL) and the Medial Meniscus are structures that are commonly injured along with the MCL. MCL injuries usually heal without surgery. However, depending on the severity, an operation may be required. A sport medicine professional will be able to assist the athlete in making a full recovery and help in minimizing the probability of reinjury.
