title: Charnley-Kerboull total hip arthroplasty for osteonecrosis of the femoral head a minimal 10-year follow-up study.
abstract: The purpose of this retrospective study was to report the minimum 10-year follow-up results of a consecutive series of 122 cemented low-friction total hip arthroplasties performed for osteonecrosis. Revision was performed for high polyethylene wear associated with periprosthetic osteolysis and socket loosening in 6 hips, and for deep sepsis in 1. The survival rate at 15 years, using revision for any reason as the end point, was 88.5%. Among the variables studied in this series, the only factor associated with a higher risk of revision was a socket wear rate greater than 0.1 mm/y. This series indicated that cemented low-friction total hip arthroplasty performed for avascular necrosis could grant satisfactory long-term results, provided that polyethylene socket wear remained below 0.1 mm/y.
