Posterior Cruciate Ligament (PCL) prevents tibia from sliding back on the femur. PCL tears are uncommon; however, they usually indicate a more significant trauma to the knee joint, and are commonly associated with other injuries (ACL tear, lateral or medial collateral ligament tear, meniscus tear). Treatment of PCL injury is individualized, and it is somewhat dictated by the concurrent injuries. If surgery is required, PCL reconstruction is performed with a graft much like ACL reconstruction.
