Posterior lateral corner (PLC) injury describes damage to static and dynamic stabilisers located around the back outer portion of the knee;
The structures of the posterior lateral corner are responsible for posterolateral stabilization of the knee. It is made up of the lateral collateral ligament, popliteus muscle tendon and the popliteofibular ligament (Riva, Sum and Hatch, 2015).
Although not very common, most of them occur with athletic trauma and motor-vehicle accidents;
PLC injuries are commonly associated with PCL or ACL injuries and surgical management is generally required
