Three mechanisms of PCL tear have been identified: A direct blow to the proximal anterior tibia in a flexed knee with forceful posterior displacement of the tibia usually results in a midsubstance tear, often with disruption of the posterior capsule. Dashboard injuries and falls on a hyperflexed knee are … See more Posterior cruciate ligament (PCL) injuries account for up to 23% of all knee ligament injuries in the general population and are most commonly seen as a result of motor vehicle accidents and sports-related injuries. The anatomic … See more The PCL extends from the lateral surface of the medial femoral condyle to the posterior aspect of the tibia. It is an intraarticular but extrasynovial structure.
