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, as 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.
