Abstract:
Injuries to the posterolateral corner (PLC) of the knee can lead to profound knee instability, especially when combined with anterior cruciate or posterior cruciate ligament injury. With increased recognition of this injury, as well as improved understanding of the pathoanatomy, surgical treatment of these injuries has evolved in favor of acute treatment including reconstructive techniques to minimize recurrent laxity and allow for early rehabilitation. This article describes the approach to the PLC and the technique for figure of 8 reconstruction.
