Lateral Collateral Ligament (LCL) Injury
The Lateral Collateral Ligament (LCL) is located on the lateral (outside) aspect of the knee and connects the lateral aspect of the tibia (shin bone) to the lateral aspect of the femur (thigh bone). It is one of the ligaments responsible for knee stability, limiting excessive twisting and inside-to-outside movements.
LCL tears may either be chronic or acute resulting in a first, second or third degree tear.
● A first degree LCL tear occurs when there is a history of overuse activity, where chronic repetitive stress to the LCL has compounded, resulting in a first degree tear. This will present with mild-moderate pain located over the lateral aspect of the knee.
● A second or third degree LCL tear occurs following an acute inside-to-outside traumatic injury to the knee. It presents with sharp pain and instant swelling over the lateral aspect of the knee.
