Salvage of infected intramedullary knee arthrodesis with vascularized free fibula and staged fixation.

Intramedullary knee arthrodesis is indicated when an infected total knee arthroplasty revision is failed. There is a high risk of infection after this procedure and the only option of treatment considered in these cases is AK amputation. We present an alternative to AK amputation in intramedullary arthrodesis infected cases that has been successful in all patients we have treated.
