Primary and revision total hip replacement without cement and with associated femoral osteotomy

Nine porous-coated total hip prostheses were implanted without cement in nine patients who had a major proximal femoral deformity. Six patients had revision and three, primary total hip replacement. In all nine patients, a well placed corrective osteotomy was needed to successfully perform the arthroplasty. The average time until union of the proximal femoral osteotomy was fifteen weeks for the patients who had a primary arthroplasty and twenty-seven weeks for the patients who had a revision arthroplasty. The average Harris hip-rating score was 94 points for the patients who had a primary arthroplasty and 84 points (range, 60 to 93 points) for those who had a revision arthroplasty. The length of follow-up averaged forty-seven months.
