(1) Background: Knee osteoarthritis (OA) is a serious orthopedic problem. In this context, the high tibial osteotomy (HTO) is an established surgical procedure to reduce the load and degeneration of the affected compartment. The aim of this investigation was to judge standing steadiness and asymmetry, pain intensity and quality of life among patients who underwent HTO surgery. (2) Methods: Twenty-five male patients with medial tibiofemoral OA finished this 2 year follow-up study. Standing balance was captured using force plates with four uniaxial sensors before, 6 weeks after, 1 year after, and 2 years after HTO surgery. The percentage weight (PW) under the foot at one side, the stability (ST) index and the weight distribution (WD) index were the main outcomes. Comparisons were conducted using repeated measures analyses of variance. (3) Results: Over time, the PW under the foot at the HTO side increased on average (p < 0.001). In terms of standing steadiness, the average ST remained similar over the time points (p = 0.71). The WD index was affected by time (p = 0.003). (4) Conclusions: In order to judge short-term effects, the PW is recommended, whereas long-term effects can be identified either through the PW or the WD index.
(1) 背景：膝关节骨关节炎（OA）是一个严重的骨科问题。在此背景下，高位胫骨截骨术（HTO）是一种既定的外科手术，用于减轻患侧关节间室的负荷和退变。本研究的目的是评估接受HTO手术患者的站立稳定性、不对称性、疼痛强度和生活质量。(2) 方法：25名患有内侧胫股关节OA的男性患者完成了这项为期2年的随访研究。在HTO手术前、术后6周、术后1年和术后2年，使用带有四个单轴传感器的测力板采集站立平衡数据。主要观察指标为一侧足底的体重百分比（PW）、稳定性（ST）指数和体重分布（WD）指数。采用重复测量方差分析进行比较。(3) 结果：随着时间的推移，HTO侧足底的PW平均增加（p < 0.001）。就站立稳定性而言，各时间点的平均ST保持相似（p = 0.71）。WD指数受时间影响（p = 0.003）。(4) 结论：为了评估短期效果，建议使用PW，而长期效果可通过PW或WD指数来确定。
