A total of 55 consecutive cementless total hip arthroplasties were done for osteoarthritis by 1 surgeon, who was not a designer of the implant, using 1 surgical technique and Porous-Coated Anatomic (Howmedica, Rutherford, NJ) hip implants. Of hips, 53 were prospectively evaluated, and 39 were followed for an average of 12.3 years (range, 10-16 years). Eight patients (8 hips) died, and 6 of 53 hips (11.3%) required revision for aseptic loosening at an average of 6.5 years. Five of 53 (9.4%) acetabular components were revised at an average of 7.9 years. Four of 53 (7.6%) femoral components were revised at an average of 5.1 years. Survivorship of these total hip arthroplasties was 98 +/- 3.9 at 5 years, 88.9 +/- 9.2 at 10 years, and 86.7 +/- 9.9 at 13 years with revision as the endpoint.
