Peroneal Nerve Palsy Induced by Impingement of the Screw in Tibial Component Subsidence -Case Report-

Peroneal nerve palsy after total knee arthroplasty is rare. Its etiology is multifactorial. Among them, stretching of the nerve by correction of severe preoperative valgus or flexion deformities, compression of the vascular supply of the nerve by the fascia, direct pressure on the nerve from the dressing are the well known factors which appear to cause development of peroneal nerve palsy. We experienced a case of the peroneal nerve palsy in infected total knee arthroplasty, which was accompanied with subsidence of the tibial prosthesis and report with review of the literature.
