Abstract
Injury to the posterior cruciate ligament (PCL) is thought to account for 3% to 20% of all knee ligament injuries.1 The true incidence of PCL injuries remains unknown because many isolated PCL injuries may go undetected.2,3 It is generally accepted that isolated ruptures of the PCL do not generally cause functional instability and are best managed by nonoperative treatment.4–7 When functional instability is present, the situation is usually not an isolated PCL injury, but a combined ligamentous injury frequently involving the posterolateral corner.8–11 Posterolateral instability of the knee in combination with PCL insufficiency is frequently the cause of functional instability, and management of this instability requires addressing not only the PCL injury, but the associated posterolateral corner injury.
