Should well-fixed uncemented femoral components be revised in infected hip arthroplasty? Report of five trial cases.

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. CONCLUSION: Two-stage revision with retention of well-fixed uncemented stems could be an alternative treatment option in hip periprosthetic infection.
