Evaluation of the porous-coated anatomic hip at 12 years

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. Copyright 2002, Elsevier Science (USA).
