Nerve injury complicating multiligament knee injury: current concepts and treatment algorithm.

Multiligament knee injuries account for <0.02% of all orthopaedic injuries, and 16% to 40% of these patients suffer associated injury to the common peroneal nerve (CPN). The proximity of the CPN to the proximal fibula predisposes the nerve to injury during local trauma and dislocation; the nerve is highly vulnerable to stretch injury during varus stress, particularly in posterolateral corner injuries.
