Femoral-side revision using dual-mobility components for failed hip resurfacing: A retrospective case series

Background: The aim of this study was to report clinical outcomes and complications of femoral-side revision using dual-mobility components for failed hip resurfacing. Methods: Eighteen consecutive patients underwent revision of failed hip resurfacing for the femoral side using dual mobility components with acetabular component retention. The mean follow-up period was 18 mo. Results: The modified Harris Hip score, visual analog scale, and Short-Form (SF)-12 scores had all improved significantly (P<0.01, P<0.05 and P<0.05, respectively) with no evidence of loosening, dislocations, or any other complications. Conclusions: Femoral-side revision only using dual-mobility liners in failed hip resurfacing appears to be a simple, safe technique with high success.
