Orthopaedic Research Laboratory, University of Southern California, Los Angeles.

The long-term results of 488 Charnley low-friction arthroplasties, performed by one surgeon, were analysed. Radiological changes were assessed using the CART nomenclature. If sepsis (1.4%) is excluded, the mechanical failure rate of one or both components requiring revision surgery was 6.5%. The incidence of radiological loosening of components was 4.7%. Kaplan-Meier survival analysis predicts an 88% mechanical survival of components at 10-12 years.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D016019	Survival Analysis	A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
