Fig. 2From: Adverse reactions to metal debris occur with all types of hip replacement not just metal-on-metal hips: a retrospective observational study of 3340 revisions for adverse reactions to metal debris from the National Joint Registry for England, Wales, Northern Ireland and the Isle of ManKaplan Meier ARMD revision rate stratified by the type of primary hip replacement. ARMD = adverse reactions to metal debris; CI = confidence intervals; THR = total hip replacement. The study population all underwent revision of their primary hip replacement implant for ARMD, therefore in the illustrated Kaplan Meier plot all three subgroups ultimately reach a survival probability of zero. This is because complete clinical data for all primary hip replacements not undergoing revision were not available for analysis in this studyBack to article page
