This study describes knee alignment and active knee range of motion (ROM) in a community-based group of 78-year old adults (n = 143) who did not have radiographic evidence of knee osteoarthritis in either knee (KL < 2). Although knee malalignment is a risk factor for knee osteoarthritis, most women and men had either valgus or varus alignments. Notably, no men were valgus in both knees. Women with both knees valgus had significantly greater body mass index (P > 0.001) than women with varus or straight knees. Men and women with valgus or varus knee alignments had generally lower ROM than individuals with both knees straight. In summary, this study highlights the complex relationships among knee alignment, ROM, body mass index, and gender in elderly adults without radiographic knee osteoarthritis.
本研究描述了一组78岁社区成年人（n = 143）的膝关节对线情况及主动膝关节活动范围（ROM），这些人双膝均无膝关节骨关节炎的影像学证据（KL < 2）。尽管膝关节对线不良是膝关节骨关节炎的一个危险因素，但大多数女性和男性存在外翻或内翻对线。值得注意的是，没有男性双膝均为外翻。双膝外翻的女性比内翻或膝关节伸直的女性体重指数显著更高（P > 0.001）。存在外翻或内翻膝关节对线的男性和女性的ROM通常低于双膝伸直的个体。总之，本研究强调了在无膝关节骨关节炎影像学证据的老年人中，膝关节对线、ROM、体重指数和性别之间的复杂关系。
