Eighty total hip arthroplasties in seventy-four patients who had had either a spontaneous or a surgical ankylosis (arthrodesis) of the hip were evaluated at nine to fifteen years (average, 10.4 years) after the total hip replacement. There was only one failure in the twenty hips of the fifteen patients who had had a spontaneous ankylosis. In contrast, twenty (33 per cent) of the sixty hips of the sixty patients who had had a surgical ankylosis had complications that were associated with the arthroplasty. Of these twenty hips, mechanical loosening developed in eleven; infection, in eight; and recurring dislocation, in one. Failure of the total hip arthroplasty was more common (p less than 0.05) in the patients who had had a previous surgical attempt at arthrodesis and in the patients who were fifty years old or less at the time of the arthroplasty. The risk of failure was not related to the length of time that the hip had been ankylosed.
对74例髋关节出现自发或手术性强直（关节融合术）的患者进行了80次全髋关节置换术，并在全髋关节置换术后9至15年（平均10.4年）进行了评估。15例出现自发强直的患者的20个髋关节中仅有1例失败。相比之下，60例接受手术性强直的患者的60个髋关节中有20个（33%）出现了与关节成形术相关的并发症。在这20个髋关节中，11个出现机械性松动；8个出现感染；1个出现复发性脱位。全髋关节置换术失败在既往接受过关节融合术手术尝试的患者以及关节成形术时年龄在50岁及以下的患者中更为常见（p<0.05）。失败风险与髋关节强直的时间长短无关。
