title: The Outcome of 241 Charnley Total Hip Arthroplasties Performed by One Surgeon 30 to 40 Years Ago.
abstract: We present the outcome of 241 consecutive low friction arthroplasties (LFAs) performed by one surgeon (GH) 30 to 40 years ago. The overall survival rate at 30 years with revision for any reason or removal of the components as the end point was 53% (43.2-62.8%) when 40 hips remained in the study. Cox regression analysis for the possible risk factors of age, gender and diagnosis revealed higher risk of the overall failure in younger patients, and higher risk of failure due to loosening in younger patients and in those with congenital hip disease. Our follow-up study at 30 to 40 years following Charnley LFA can be used as a benchmark for comparison with the newer methods of total hip arthroplasty.
