Fig. 3A–B.

(A) Survival curve showing the rate of survival with any cause of stem removal counted as a failure. Patients were censored at death or last followup. This shows 5-, 10-, 15-, and 20-year survival rates of 76.1%, 73.5%, 62.8%, and 46.1%, respectively. (B) Survival curve where only aseptic loosening is the mode of failure. Patients were censored at death, last followup, or any other cause of stem removal or revision. This shows 20-year survival rates of 86.5%. Ninety-five percent confidence intervals are included on both curves.
