本研究旨在确定膝关节骨关节炎（KOA）患者髂胫束（ITB）的厚度和刚度，并确定与ITB特性相关的步态参数。纳入了18例影像学诊断为内侧KOA和膝关节疼痛的女性患者（年龄：69.7 ± 5.9岁，体重指数：23.0 ± 3.1 kg/m2）和22例年龄匹配的无膝关节疼痛的女性个体（年龄：69.1 ± 7.0岁，体重指数：21.6 ± 3.6 kg/m2）。在受试者处于仰卧位的情况下，在髌骨近端极的高度处获得剪切波弹性成像图像，并计算ITB厚度和剪切波速度，剪切波速度是刚度的替代指标。在KOA患者中，使用运动分析系统计算行走过程中的膝关节和髋关节角度和力矩。KOA患者的剪切波速度显著高于无症状成人（分别为11.3 ± 1.0 vs. 10.0 ± 1.8 m/s; p = 0.010）;然而，两者之间的厚度没有差异（分别为2.1 ± 0.3 vs. 2.0 ± 0.3 mm; p = 0.705）。膝关节内收力矩的时间积分值（β = 0.507，p = 0.032）和髋关节屈曲力矩的最大值（β = 0.498，p = 0.036）与剪切波速度相关。同时，没有参数与厚度相关。KOA患者的ITB比无症状成人更僵硬;这种更僵硬的ITB与行走时更大的膝关节内收和髋关节屈曲力矩相关。临床意义：在KOA患者中，更大的机械载荷与更僵硬的ITB相关。
This study aimed to determine the thickness and stiffness of the iliotibial band (ITB) in patients with knee osteoarthritis (KOA) and to identify the gait parameters that are associated with ITB properties. Eighteen female patients with radiographically diagnosed medial KOA and knee pain (age: 69.7 ± 5.9 years, body mass index: 23.0 ± 3.1 kg/m2) and 22 age‐matched female individuals without knee pain (age: 69.1 ± 7.0 years, body mass index: 21.6 ± 3.6 kg/m2) were included. Shear wave elastography images were obtained at the height of the proximal pole of the patella with the participants in the supine position, and the ITB thickness and shear wave velocity, which is a surrogate measure of stiffness, were calculated. In patients with KOA, the knee and hip joint angles and moments during walking were calculated using a motion analysis system. The shear wave velocity was significantly higher in patients with KOA than in asymptomatic adults (11.3 ± 1.0 vs. 10.0 ± 1.8 m/s, respectively; p = 0.010); however, the thickness did not differ between them (2.1 ± 0.3 vs. 2.0 ± 0.3 mm, respectively; p = 0.705). The time‐integral value of the knee adduction moment (β = 0.507, p = 0.032) and maximum value of the hip flexion moment (β = 0.498, p = 0.036) were associated with the shear wave velocity. Meanwhile, no parameters were associated with the thickness. The ITB was stiffer in patients with KOA than in asymptomatic adults; such a stiffer ITB was associated with greater knee adduction and hip flexion moments during walking. Clinical Significance: Greater mechanical loading was associated with a stiffer ITB in patients with KOA.
