To determine the effectiveness of staged reimplantation for the treatment of periprosthetic hip infection caused by resistant microorganisms, we performed a retrospective case-control study on 37 consecutive patients who had a culture-proven periprosthetic hip infection treated using a 2-stage reimplantation protocol. Twenty-four patients infected by resistant microorganisms were compared with 13 patients infected by nonresistant microorganisms. The second-stage reimplantation procedure was possible in 34 (92%) of the 37 patients, but the remaining 3 required permanent resection because of persistent infection. At a mean follow-up Of 4.4 years, there were 4 recurrent infections and I aseptic cup loosening. Overall treatment failure rate was 22%. All failures Occurred only in the resistant microorganism group and none in the nonresistant microorganism group (33% vs 0%; P = .032). Current 2-stage reimplantation protocol showed a high rate of treatment failure in our patients with a periprosthetic hip infection caused by resistant microorganisms.
