The PCL, compared to the ACL, has the intrinsic ability to heal and regain functionality after injury. Physiologically correct positioning of the PCL during conservative or post-surgical rehabilitation is important, as the PCL experiences variable tensile forces during knee flexion, and healing of the PCL in an elongated position can lead to chronic instability and disability. Insufficient healing after a PCL rupture leads to significant pathologies, such as chronic anterior knee pain or knee OA.
