title: Should well-fixed uncemented femoral components be revised in infected hip arthroplasty? Report of five trial cases.
abstract: BACKGROUND
  Well-fixed femoral component removal remains difficult and complicated.
  
  
  METHODS
  We report herein the outcomes of two-stage surgery involving retention of bone-ingrown uncemented stems, aggressive soft-tissue debridement, and delayed reimplantation of an acetabular component in 5 patients for infected hip arthroplasty.
  
  
  RESULTS
  By a mean follow-up point of 4.2 years after the second-stage operation, none of the 5 patients experienced recurrence of infection, and the mean Harris hip score had improved from 63 to 86 points by the latest follow-up evaluation.
  
  
  CONCLUSIONS
  Two-stage revision with retention of well-fixed uncemented stems could be an alternative treatment option in hip periprosthetic infection.
