OBJECTIVES
To compare foot posture in people with and without medial compartment knee osteoarthritis (OA), and to assess association between its abnormalities and medial compartment knee OA.
METHODS
We compared the foot posture of patients with clinically and radiographically-confirmed medial compartment knee OA and asymptomatic healthy controls using the foot posture index (FPI), navicular height, and the medial arch.
RESULTS
We included 100 patients and 80 asymptomatic controls. The mean age of patients was 59 ± 7 (44-76) years and 48 ± 9 (28-60) years in the control (p=0.06). Patients group have more pronated foot for FPI (1.50 ± 2.68 vs 0.72 ± 2.63; p=0.05), more flat foot (42% vs 22%; p=0.03), and less pes cavus than the control group (58% vs 77%; p=0.004). However, there was no significant difference between the groups in the navicular height (3.90 ± 0.85 cm vs 4.00 ± 0.76 cm; p=0.41). In multivariate statistical analysis, after adjusting for age and body mass index, pronated foot in FPI (OR=1.22, 95%IC= [1.06-1.40], p=0.005), and pes cavus (OR=0.32, 95%IC= [0.11-0.93], p=0.03) had a significant correlation with the knee osteoarthritis.
CONCLUSION
Pronated foot posture and flat foot are significantly associated with medial compartment knee osteoarthritis.
目的
比较有和没有内侧间室膝关节骨关节炎（OA）的人群的足部姿势，并评估其异常与内侧间室膝关节OA之间的关联。
方法
我们使用足部姿势指数（FPI）、舟骨高度和内侧足弓，比较了临床和影像学确诊的内侧间室膝关节OA患者与无症状健康对照者的足部姿势。
结果
我们纳入了100例患者和80例无症状对照者。患者的平均年龄为59±7（44 - 76）岁，对照组为48±9（28 - 60）岁（p = 0.06）。患者组FPI的足部旋前程度更高（1.50±2.68 vs 0.72±2.63；p = 0.05），扁平足更多（42% vs 22%；p = 0.03），高弓足比对照组少（58% vs 77%；p = 0.004）。然而，两组之间的舟骨高度无显著差异（3.90±0.85 cm vs 4.00±0.76 cm；p = 0.41）。在多变量统计分析中，调整年龄和体重指数后，FPI中的足部旋前（OR = 1.22，95%IC = [1.06 - 1.40]，p = 0.005）和高弓足（OR = 0.32，95%IC = [0.11 - 0.93]，p = 0.03）与膝关节骨关节炎有显著相关性。
结论
足部旋前姿势和扁平足与内侧间室膝关节骨关节炎显著相关。
