Posterior Cruciate Ligament Injuries

In brief Posterior cruciate ligament (PCL) injuries typically occur during hyperflexion or with a blow to the knee during hyperextension. Physical findings such as a positive posterior drawer test or a posterior sag and standard x-rays are keys to expedient diagnosis. Acute isolated PCL injuries often are treated conservatively with strengthening and proprioceptive exercises. Chronic isolated PCL injuries and combined ligament injuries usually require surgical reconstruction.
