Cementless cup fixation in total hip arthroplasty after 5-8 years

A series of 199 total hip arthroplasties was performed using a porous-coate d, hemispherical press-fit acetabular cup. At a mean follow-up of 91.5 mont hs 158 cups were available for clinical and radiological review, The mean a ge of the patients at the time of the index arthroplasty was 62.5 years. Th e mean Harris Hip score at final follow-up was 87.3. No shells were revised although eccentric polyethylene wear prompted liner replacement in two cas es. Osteolysis was noted in six cases but predominantly in relation to the femoral stem. Focal pelvic osteolytic lesions were rare. All the cups were classified as stable on radiography.
