Abstract 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.
