In ruptures of the posterior cruciate ligament, the tibia tends to sag backwards in relation to the tibia. PCL are rarer than ACL tears andit is usually associated with damage to other ligaments around the knee especially the posterolateral corner (PLC). patients with isolated tears of the posterior cruciate ligament often do very well with conservative treatment aimed at strengthening the quadriceps which can largely compensate for the loss of the PCL. However when multi-ligament injuries occur these are best treated surgically.
