Answer

Patients with peroneal nerve palsy after knee arthroplasty or tibial osteotomy should initially be treated by removing all constrictive dressings and repositioning the knee to 20-30° of flexion. If an expanding hematoma is noted, urgent exploration is warranted. If functional recovery does not occur within 2 months, nerve exploration or release is advocated. The time interval between symptom onset and decompression appears to affect the final functional outcome. However, the severity of the preoperative palsy does not seem to affect recovery.
