Sixty-four total articular replacement arthroplasties were performed in 60 patients with an average follow-up period of 24 months. Ninety-three percent of the patients had little or no pain at the time of follow-up examination; 83% of the patients were able to walk unlimited distances; 97% of the patients had a postoperative flexion range of 90 degrees or greater. The incidence of progressively increasing radiolucency at the bone-cement interface in the acetabular area was disturbingly high. There was also a progressive occurrence of bone sclerosis along the lateral border of the prosthetic stem, indicating that the stem provoked bony changes in response to stress transfer. Despite these responses, this procedure has shown better results than those in which other types of conservative or resurfacing devices were used during a two-year evaluation period.
对60例患者实施了64例全关节置换术，平均随访期为24个月。93%的患者在随访检查时几乎没有疼痛或完全无痛；83%的患者能够无限制行走；97%的患者术后屈曲范围达90度或更大。髋臼区域骨水泥界面处放射性透亮度逐渐增加的发生率高得令人不安。沿假体柄外侧缘也逐渐出现骨硬化，表明假体柄因应力传递引发了骨质改变。尽管有这些反应，但在两年的评估期内，该手术的效果优于使用其他类型保守或表面置换装置的手术。
