A retrospective study of 100 CONSERVE PLUS hip resurfacing devices implanted in patients between 1996 and 1998 by a single surgeon showed that none of the resurfacing arthroplasties failed in the 28 patients who had a femoral component of >46 mm. Eleven hips had conversion to total hip arthroplasty.
Five hips had narrowing of the femoral neck, three had osteolysis and 20 had signs of neck-socket impingement. Further assessment after a longer period of follow-up is required for comparison with conventional total hip arthroplasty.
