Two hundred one consecutive, primary, noninfected Charnley (Thackray, Leeds) hip arthroplasties, implanted from 1968 to 1985 due to adult-onset rheumatoid arthritis, were matched in pairs with respect to year of operation, age, and sex with 201 Charnley prostheses implanted due to osteoarthritis. The 10-year survival estimate for nonrevisions was 95% in the rheumatoid group and 89% in the osteoarthritic group. Using definite radiographic loosening as a determinant, the 7-year survival rate for stems increased from 80% to 96% for both groups after the introduction of new cementing techniques, and the relative risk for stem loosening was decreased to one fifth. In the rheumatoid arthritis group, the 7-year radiographic socket survival increased from 87% to 96%, an increase ascribed to the overall effect of the introduction of flanged sockets, bone-grafts in acetabular protrusion, the rejection of the pilot hole technique, and improvements in the cement handling technique. In the osteoarthritis group the radiographic socket survival rate at 7 years was 97% and at 10 years was 95%.
1968年至1985年期间，因成人类风湿性关节炎植入的201例连续、原发性、未感染的查恩利（泰克雷，利兹）髋关节置换术，在手术年份、年龄和性别方面与201例因骨关节炎植入的查恩利假体进行配对。类风湿组非翻修的10年生存率估计为95%，骨关节炎组为89%。以明确的影像学松动为判定标准，采用新的骨水泥固定技术后，两组柄的7年生存率从80%提高到96%，柄松动的相对风险降至五分之一。在类风湿性关节炎组中，7年影像学髋臼生存率从87%提高到96%，这一提高归因于带凸缘髋臼、髋臼突出症骨移植、导向孔技术的摒弃以及骨水泥处理技术改进的总体效果。骨关节炎组7年影像学髋臼生存率为97%，10年为95%。
