A prospective study was undertaken over a 2-year period to evaluate the clinical efficacy of using the Zweymuller femoral component (Allopro, Berne, Switzerland) in cementless total hip arthroplasty. Forty consecutive patients (46 hips) were included for final evaluation. Ninety-four percent of the femurs were classified as Dorr class B or C before surgery. The mean follow-up period was 50 months (median, 48 months). Ninety-eight percent of the hips were rated good or excellent clinically. No stem was classified as definitely loose. No hip has required any reoperation. There was no incidence of femoral or acetabular osteolysis up to 6 years.
