Long-term results of Charnley low-friction arthroplasty of the hip.
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.
