The PCL is one of four major stabilising ligaments of the knee. It functions to prevent backwards movement of the shin bone (tibia) in relation to the thigh bone (femur) whilst also providing rotational stability and preventing hyperextension.
The PCL is commonly injured in a traumatic event resulting in a direct blow to the front of the knee forcing the tibia backwards in relation to the femur, or from a twisting or hyperextension injury.
