A Case Report on Deep Peroneal Nerve Palsy Following Patella Dislocation

Abstract

Background: Peroneal nerve injury following knee dislocation is a known complication described in numerous case reports. However, this complication has very rarely been described following patellar dislocation. We focus on the presentation and subsequent treatment of this complication. Case: We describe a thirteen-year-old patient who developed a deep peroneal nerve palsy following patellar dislocation. After her initial visit for patellar dislocation, our patient developed foot drop over the course of one week. Six months following her injury, she had fully functional recovery of the nerve with conservative treatment. Conclusion: Residual deep peroneal neuropathy following patellar dislocation is an exceedingly rare complication. Treatment should consist of conservative measures initially; however, surgical exploration may become necessary.

Preventable iatrogenic cause of foot-drop in knee injuries with literature review

“…Surgical intervention may be required in the form of neurolysis, nerve repair, or tibialis posterior tendon transfer depending on case to case basis. 16 In the cases presented here, the first case was treated with removal of traction and the second case was treated by shifting the traction to distal femur which was followed by AFO and passive mobilization. After 6–7 months of follow-up, the recovery is yet to happen.…”
