SELECTIVE DEEP PERONEAL NERVE INJURY ASSOCIATED WITH ARTHROSCOPIC KNEE SURGERY

We report 3 cases of isolated deep peroneal nerve injury as a complica tion of arthroscopic knee surgery. At the level of the knee joint, the deep and superficial peroneal nerves are usually joined as the common peroneal nerve. However, because of the fascicular structure, a parti al nerve injury can result in an isolated injury to the deep peroneal nerve fibers. Due to the intraneural topography of the peroneal nerve, electrodiagnostic studies in a partial nerve injury may erroneously i ndicate a more distal lesion. (C) 1993 John Wiley & Sons, Inc.
