Peroneal nerve palsy following knee dislocation: pathoanatomy and implications for treatment.

Abstract

Peroneal nerve palsy following knee dislocation is a serious problem, and neurolysis at the time of knee reconstruction does not always result in return of peroneal nerve function. We describe peroneal nerve pathoanatomy in three patients in whom late exploration of the peroneal nerve was performed because of ongoing absence of ankle dorsiflexion. We identified frank nerve rupture in two patients and a lengthy neuroma in continuity in one which extended far proximal to the fibular head and well above the previous surgical incision used for peroneal nerve neurolysis at the time of knee reconstruction. In light of the current state of microneural surgery and the potential to reconstruct nerve defects, we discuss how our findings impact on treatment, and provide recommendations which may improve recovery of peroneal nerve function in future cases.
