Abstract
Providing a long-lasting total hip arthroplasty for patients younger than 50 years remains one of the greatest challenges for modern arthroplasty surgery. We retrospectively reviewed 221 patients younger than 50 years who underwent 299 uncemented total hip arthroplasties from 1983 to 2000. We assessed 5- to 15-year survival with revision as the endpoint. Femoral stem survival was 99.3% (range, 98.4-100%), 98.9% (range, 97.7-100%), and 96.8% (92.5-100%) at 5, 10, and 15 years, respectively. Including all component designs acetabular survival was 98.7% (range, 97.4-100%), 84.6% (78.8-90.4%), and 52.5% (40.7-64.3%) at 5, 10, and 15 years, respectively. Overall survival was 46.8% (33.5-58.1%) at 15 years. Total hip arthroplasties performed for hip dysplasia had lower 10-year and 15-year survival. Zirconium-on-polyethylene articulations had lower acetabular revision rates compared with cobalt-chrome-on-polyethylene. Sixty-nine revisions were performed, most commonly for polyethylene wear. Uncemented femoral stems resulted in 90% survival at 15 years followup in patients younger than 50 years at index operation. Contemporary bearing surfaces in association with such stems may provide long-lasting total hip arthroplasties, even in young, active patients.Keywords
