The consequences of dislocation following total hip arthroplasty were assessed using quantitative gait analysis. As a preliminary study, a review of 18 patients having undergone hip arthroplasty without dislocation provided as understanding of the improvement in gait in the first two years after surgery. Seven patients with a single dislocation and six patients with multiple dislocations were compared with patients matched according to age and preoperative gait characteristics and who experienced an uncomplicated recovery following hip arthroplasty. One year after surgery patients with a single dislocation could not be differentiated from the matched patients with respect to gait velocity and single limb support time. However, patients, with multiple dislocations walked significantly slower and had a significantly decreased single limb support time in the involved extremity than their respective matched patients.
采用定量步态分析评估全髋关节置换术后脱位的后果。作为一项初步研究，对18例未发生脱位的髋关节置换术患者进行回顾，以了解术后头两年步态的改善情况。将7例单次脱位患者和6例多次脱位患者与根据年龄和术前步态特征匹配且髋关节置换术后恢复顺利的患者进行比较。术后一年，单次脱位患者在步态速度和单腿支撑时间方面与匹配患者没有差异。然而，多次脱位患者行走速度明显较慢，患侧肢体的单腿支撑时间比各自匹配的患者明显缩短。
