Lateral Collateral Ligament Injury
The lateral collateral ligament (LCL) is one of the four ligaments that helps stabilise the knee. It spans from the bottom of your thigh bone (femur) to the top of your fibula (smaller of the 2 bones in your calf.
A Lateral collateral ligament (LCL) injury is a stretch, partial tear, or complete tear of the ligament on the outside of the knee.
The LCL is usually injured by a force directed from the inside surface of the knee, which puts stress on the outside surface of the knee.
