Abstract

Aims: Recurrent infection following two-stage revision total hip arthroplasty (THA) for prosthetic joint infection (PJI) is a devastating complication. The purpose of this study was to report the survival of repeat two-stage revision hip arthroplasty, describe complications, and identify risk factors for failure. Patients and Methods: We retrospectively identified 19 hips (19 patients) that had undergone repeat two-stage revision THA for infection between 2000 to 2013. There were seven female patients (37%) and the mean age was 60 years (30 to 85). Survival free from revision was assessed via Kaplan-Meier analysis. The patients were classified according to the Musculoskeletal Infection Society (MSIS) system, and risk factors for failure were identified. Mean follow-up was four years (2 to 11). Results: Gram-positive bacteria were responsible for 16/17 (94%) of the re-infections where microbes were identified. Following the repeat two-stage exchange arthroplasty, survival free from any revision was 74% (95% confidence interval (CI) 56% to 96%, 14 at risk) at two years and 45% (95% CI 25% to 75%, five at risk) at five years. Failure to control infection resulted in re-operation or revision in 42% of patients (8/19). Survival free from revision was not dependent on host grade. Conclusion: Re-infection after two-stage exchange hip arthroplasty for PJI presents a challenging scenario. Repeat two-stage exchange arthroplasty has a low survival free from revision at five years (45%) and a high rate of re-infection (42%).
