ABSTRACT
Patients older than 70 years who underwent primary total hip arthroplasty using a modular proximally porous-coated femoral stem with an ingrowth hemispherical acetabular component were evaluated. This included 135 hips in 122 patients, with an average 5-year follow-up period. This study included 96 patients (107 hips) still living; 26 patients (28 hips) patients had died, and 8 patients were lost to follow up. In this study, 93% of patients had little or no pain, and 95% were extremely or very satisfied with the operation. Mean Harris Hip score was 83, with a Short Form-36 (SF-36) physical component and mental component summary score of 41 and 51, respectively. Osteolysis surrounding the femur was seen in 8 hips (7%) and around the acetabulum in 6 hips (5%). No components were loose or required revision.
