Common peroneal nerve palsy after lateral unicompartmental knee arthroplasty

Unicompartmental knee arthroplasty is now being used more commonly to treat single compartment disease of knee, with very encouraging results. We report on a rare case of common peroneal nerve palsy; 8 years after lateral unicompartmental knee arthroplasty. This palsy was caused by pressure on the common peroneal nerve, due to posterior migration of tibial component. Copyright 2003, Elsevier Science (USA). All rights reserved.
