Lateral collateral ligament injuries

The lateral collateral ligament (LCL) is like a thin cord that runs from the bottom of your thigh bone to the top of your fibula bone on the outside of your knee.

It's a rare lesion and it's not usually damaged on its own but you need to have it repaired quickly +++ in the weeks following the injury. Late repair is difficult.

Varus instability allows the diagnosis : With the patient lying flat, and the knee held at about 30° of flexion, the shin is shifted to the inside. Insufficiency of the MCL will allow the knee to "open up " excessively compared to the other knee. Diagnosis may be difficult and MRI is to be performed if there is a doubt.+++
