title: Use of a modular tapered fluted femoral component in revision total hip arthroplasty following resection of a previously infected total hip: minimum 5-year follow-up.
abstract: Femoral reconstruction in the setting of two stage reimplantation can be difficult and substantial reoperation rates due to implant loosening have been reported. We retrospectively reviewed 28 male and 29 female patients who underwent a two-stage reimplantation using a modular, tapered femoral stem. The mean clinical follow-up was 62 months. The mean Harris Hip score at 5-year follow-up was 76. Two stems were revised for aseptic loosening. Reinfection occurred in 16% of patients. Stem survivorship was 87% at 5-years. Use of a modular tapered stem provided a high rate of stable femoral fixation and acceptable rate of reinfection in two stage treatment of infected THA.
