title: Knee arthrodesis after infected tumor mega prosthesis of the knee using an intramedullary nail for callus distraction.
abstract: BACKGROUND
  Infected tumor endoprosthesis of the knee in young patients can prove to be challenging. Common procedures are débridement and prosthesis reimplantation, amputation, revision arthroplasty, and arthrodesis.
  
  
  METHODS
  We report the case of a 44-year-old man treated by arthrodesis followed by callus distraction after removal of an infected tumor mega prosthesis (Kotz type). Callus distraction was performed over a distance of 11 cm in 4 months using a femorotibial intramedullary nail with an external traction rope-winch system.
  
  
  OBJECTIVE
  The clinical, radiological, technical, and therapeutic features are discussed.
