title: One stage conversion of an infected fused knee to total knee replacement - a surgical challenge.
abstract: OBJECTIVE
  Two-stage revision arthroplasty is a common technique for the treatment of infected total knee replacement. Few reports have addressed the conversion of a fused knee into a total knee replacement. However, there is no case reported of converting an infected fused knee into a hinge knee using a one-stage procedure.
  
  
  METHODS
  We report on a 51-year old male patient with an infected fused knee after multiple surgeries.
  
  
  CONCLUSIONS
  A one-stage conversion of septic fused knee into total knee arthroplasty by a rotational hinge prosthesis was performed. The case highlights that with profound preoperative assessment, meticulous surgical technique, combined antibiotic treatment and the right implant, one-stage revision in a surgical challenge may have a role as a treatment option with good functional outcome.
