Is anatomy of the posterolateral corner always the same?

Luning Sun, Darius E. Lin, Jinzhong Zhao


Multiple ligament injuries of the knee usually occur after high-velocity trauma, with the posterolateral corner (PLC) being the most commonly injured. It has been estimated that 60% of patients with posterior cruciate ligament (PCL) injuries also have a concomitant injury to one or more of the posterolateral structures (1-4).
