Previous surgery had been undertaken for 33 hips (8.6%). During the study period 218 patients with 236 hips (62%) died, 42 hips (11%) were revised and 110 hips (29%) in 96 patients were available for review. The acetabular components were varied and some designs are now obsolete, however they were all cemented. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> With an endpoint of revision for aseptic loosening or lysis, survivorship of the stem at 22.8 years was 99.0% (95% confidence interval (CI) 97.0 to 100). One stem was revised 21 years post-operatively in a patient with Gaucher\u2019s disease and proximal femoral osteolysis. Survivorship with aseptic loosening or lysis of the acetabular component or stem as the endpoint at 22.8 years was 89.3% (95% CI 84.8 to 93.8). With an endpoint of revision for any reason, overall survivorship was 82.9% (95% CI 77.4 to 88.4) at 22.8 years. Radiological review showed excellent preservation of bone stock at 20 to 25 years, and no impending failures of the stem. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> The Exeter femoral stem continues to perform well beyond 20 years.
