Total ankle arthroplasty is being used more frequently as an alternative for arthrodesis in final stages of ankle osteoarthritis. However, there are few studies which describe the biomechanics of gait of these patients.
Between March 2006 and May 2011, 17 patients (n=18 ankles) suffering end-stage osteoarthritis of the ankle who underwent an ankle replacement (HINTEGRA) were evaluated retrospectively. We evaluated clinical, radiological and biomechanical gait parameters using the NedAMH/IBV dynamometric platform.
At last follow-up (average: 37 months), the AOFAS score improved from 31 to 83 with a high rate of satisfaction (83.3%). Kinetic gait parameters were more similar to a healthy ankle. We detected a radiolucent line in 8 patients (44%) without any subsidence case.
Our study showed a high rate of satisfaction and biomechanics of the gait similar to a healthy ankle. The complication rate was analogous to those previously published in the literature.
全踝关节置换术作为终末期踝关节骨关节炎关节融合术的替代方法，应用越来越频繁。然而，描述这些患者步态生物力学的研究较少。
回顾性评估2006年3月至2011年5月期间17例（18个踝关节）接受踝关节置换术（HINTEGRA）的终末期踝关节骨关节炎患者。我们使用NedAMH/IBV测力平台评估临床、放射学和生物力学步态参数。
在最后一次随访时（平均37个月），美国足踝外科协会（AOFAS）评分从31分提高到83分，满意度较高（83.3%）。动力学步态参数与健康踝关节更相似。我们在8例患者（44%）中检测到透亮线，无任何下沉病例。
我们的研究显示满意度较高，步态生物力学与健康踝关节相似。并发症发生率与先前文献报道的类似。
