Revision Rate and Patient-Reported Outcome After Hip Resurfacing Arthroplasty: A Concise Follow-Up of 1064 Cases.
We investigated survival and outcomes in 1064 HRA hips operated on between 1998 and 2009. After a mean of 7.8 years, 771 patients (72.4%) completed questionnaires, with a further 160 (15.0%) contacted by phone and 18 (1.7%) had died. There were 54 revisions. Overall implant survival at 10 years was 94.4%. Independent predictors of lower survival were female gender (P=0.015) and cup inclination ≥55° (P<0.001). Woman with cup inclination ≥55° had the highest failure rate with 10-year survival of 69.3%. Vertical cup inclination ≥55° did worse than cups <55° in both men and women. Overall men did better than women, and men with cups <55 degrees did best. Men had significantly better patient-reported outcome scores than woman.
