title: One-stage versus two-stage bilateral autophor ceramic total hip arthroplasty.
abstract: Noncemented autophor ceramic total hip arthroplasty (ACTHA) has been developed in recent years for treatment of advanced hip diseases. Bilateral ACTHAs were routinely performed in two operations at a four- to six-month interval. There have been no reported series of one-stage bilateral ACTHAs. In this retrospective study, the authors compared 20 patients who had bilateral one-stage ACTHAs with 15 patients who had similar bilateral arthroplasties in two stages. The study revealed no significant differences in estimated intraoperative blood loss, postoperative hemovac drainage, total amount of blood transfusion, intra- or postoperative complications, or postoperative functional results in the two groups. There was no difference in achieving prosthesis stability by interface bone growth, in spite of a significant difference in weight-bearing status during the immediate postoperative period. The one-stage bilateral procedure, however, offered advantages over two-stage bilateral procedures, including shorter length of hospital stay (18 days versus 27 days), shorter operative time (148 minutes versus 245 minutes), shorter period of disability (86 days versus 202 days), and reduced economic costs (about 10% less). There was no increase in the risk of morbidity or mortality in the one-stage bilateral group. In selected cases, one-stage bilateral ACTHA would be preferable.
