Implant survival rate following revision surgery performed for adverse reactions to metal debris at up to four years. Shaded area represents the respective upper and lower limits of the 95% confidence intervals (CIs). Risk table indicates the number of hips at risk at one-year intervals, with the corresponding number in brackets detailing the number of hips undergoing re-revision surgery during each one-year interval. The cumulative four-year implant survival rate was 83.8% (95% CI 76.7 to 88.9).
