Lateral Collateral Ligament (LCL) injury
What is Lateral Collateral Ligament (LCL) injury?
The lateral collateral ligament (LCL) is a ligament located on the outer side of the knee and connects the femur (thigh bone) to the fibula (shin bone). The purpose of the LCL is to help keep the knee joint stable, especially on the outside. Injuries to the LCL range a sprain (grade I), partially rupture (grade II) to complete rupture of the ligament (grade III). This injury accounts for 7-16% of all knee ligament injuries.
