We aimed to investigate the factors influencing gait improvement in the patients who had undergone total hip arthroplasty. We performed gait analysis on 43 female patients with unilateral hip osteoarthritis. All the patients were analyzed before and at 2, 6, and 12 months after the surgery. There were significant reductions in spatiotemporal parameters in the patients with hip osteoarthritis compared with the control group. The mean values of the spatiotemporal parameters of the patients showed considerable improvement by 12 months after surgery; however, they did not reach the same values as those observed in the healthy subjects. The stage of osteoarthritis and the changes in the leg-length discrepancies were the factors that most influenced gait improvement after total hip arthroplasty throughout the follow-up period.
我们旨在研究影响全髋关节置换术后患者步态改善的因素。我们对 43 例单侧髋关节骨关节炎女性患者进行了步态分析。所有患者均在术前及术后 2、6 和 12 个月进行了分析。与对照组相比，髋关节骨关节炎患者的时空参数有显著降低。术后 12 个月，患者时空参数的平均值有了相当大的改善，但仍未达到健康受试者的水平。在整个随访期间，关节炎分期和下肢长度差异的变化是影响全髋关节置换术后步态改善的最重要因素。
