本研究的目的是调查54例中度膝关节内侧骨关节病患者的临床症状、静态影像学测量结果和膝关节行走时的负荷分布之间的关系。膝关节内翻畸形通过静态影像学测量评估为髋关节-膝关节-踝关节（HKA）角，并使用Kistler测力板系统评估额状面膝关节力矩范围。膝关节内收力矩与临床症状无相关性，但在区分患者和正常对照组时，站立中期内收力矩比峰值内收力矩更重要。内收力矩峰值与患者的性别、体质量有关，而站立中期内收力矩峰值与体质量、膝内翻畸形有关。峰值内收力矩与HKA角之间存在弱相关性（r = 0.32，P < 0.05），并且即使在将站立中期力矩标准化为体重之后，站立中期（即站立期的50%）的峰值内收力矩与HKA角之间也存在中等程度的高相关性（r = 0.46，P < 0.001）。因此，在我们的患者中，站立中期膝关节内外侧负荷的20%可以解释为骨关节病膝关节的内翻畸形。
The purpose of this study was to investigate the relationship between clinical symptoms, static radiographic measurements, and of load distribution during walking at the knee, in 54 patients with moderate medial osteoarthrosis of the knee. Varus deformity of the knee was assessed from static radiographic measurements as the Hip-Knee-Ankle (HKA) angle, and range of moments at the knee in the frontal plane were assessed using a Kistler force plate system. No correlations between clinical symptoms and radiographic parameters or moments at the knee were found. The adduction moment in mid stance was more important than the peak adduction moment in differentiating between patients and normal controls. The amplitude of the peak adduction moment depended on the sex and body mass of the patients, while the amplitude of the mid stance adduction moment depended on body mass and the varus deformity of the knee. There was a weak correlation between the peak adduction moment and the HKA-angle (r = 0.32, P < 0.05) and there was a moderately high correlation between the peak adduction moment in mid stance, i.e 50% of the stance phase, and the HKA angle (r = 0.46, P < 0.001) even after normalization of the mid stance moment to body mass. Accordingly, 20% of the medio-lateral knee load in mid stance during walking could be explained by the varus deformity of the osteoarthrotic knee in our patients.
