[Primary total hip arthroplasty in patients with rheumatoid arthritis].
Total hip arthroplasty has become a successful way of treating the painful and destroyed hip joint in the patient with rheumatoid arthritis (RA). Two hundred twenty (135 cemented and 85 noncemented) total hip arthroplasties were performed in 180 patients with rheumatoid arthritis. The average age was 48.61 years and the average follow-up was 8.4 years. Clinical evaluation was based on a Harris hip score that showed significant improvement in pain and function preoperatively compared with pain and function at followup. There were two deep infections requiring removal of the prosthesis. Four cemented acetabular cups and one cemented femoral component were revised due to aseptic loosening. Three acetabular rings were revised due to aseptic loosening. The relatively inferior results of total hip arthroplasty among RA patients is due not only to fixation method, but also to the poorer bone quality and weakening musculature. The results in these patients suggest that cementless total hip arthroplasty might become a successful way of treating the destroyed hip joint in the patient with rheumatoid artritis.
