Aims: A femoral stem design (BiCONTACT¨) for cementless þxation is being used without any technical modiþcation since 14 years. The long term results should be evaluated in this study. Methods: A consecutive series was continuously monitored in a prospective follow-up study. A survival analysis was performed, clinical results were rated according to the HARRIS Score. Results: There were 236 patients with 250 hips, mean age at time of implantation was 58.2 years. Indications for THR included osteoarthritis (62.4%), dysplasia (16.8%), trauma (8.4%) and femoral head necrosis (16.8%). Average time of follow-up evaluation was 11.8 years (range 10.6 Ð 13.7 years). At follow-up, 44 patients have died and three could not be located. Eight patients have been revised, 2 for infection, 1 for recurrent dislocation, 2 for component undersizing with rapid subsidence and 1 for aseptic loosening of a varus-malaligned stem. Two stems have been revised during acetabular revision. Survival estimate showed an overall survival of 96.6% after 14 years (conþdence limits: 98.4% (upper) and 92.8% (lower)). The average HARRIS hip score at time of follow-up was 78.3 points. Radiologically, tiny reactive lines (< 2mm) were present in the distal zones of the femoral shaft in 39%, but no radiolucencies could be found in the proximal anchoring zone. Conclusions: The long-term follow-up results with the BiCONTACT¨ femoral component are encouraging and are comparable to those of modern techniques of cementing in primary total hip arthroplasty.
