The cumulative survival rate of the implants with revision as the endpoint. The survival rates for the cup were 100% at 5 years, 94.1% at both 10 and 15 years, and 62.8% at 18 years. The survival rates for the stem were 100% at 5 years and 95.8% at 10, 15, and 18 years. The overall survival rates (of both the cup and stem) were 100% at 5 years, 95.8% at 10 years, 82.1% at 15 years, and 54.8% at 18 years
