摘要

为了尽量减少膝关节骨关节炎的影响,建议使用侧楔鞋垫。诱导具有临床意义的生物力学反应所需的楔入量仍然存在争议。本研究旨在探讨不同数量楔入对症状性膝内侧OA的直接生物力学影响。采用三维运动捕捉系统和五个力平台,沿10米的人行道获取步行运动学和动力学数据。每个参与者按随机顺序测试六种不同的侧向楔形鞋垫(0、2、4、6、8和10°)。38例膝关节内侧骨关节炎患者被招募。与控制条件(0°鞋垫)相比,在所有实验条件下,鞋垫的应用导致膝关节外内收力矩的第一个峰值的增量减少。鞋垫分别高于8°和6°时,踝关节外翻峰值和膝关节外内收力矩第一峰值踝关节外翻显著增加(p < 0.05)。侧楔鞋垫的轻微变化,大于2°,似乎会引起膝关节骨关节炎患者显著的生物力学变化。

Can Slight Variations to Lateral Wedge Insoles Induce Significant Biomechanical Changes in Patients with Knee Osteoarthritis?
Lateral wedge insoles are recommended in order to minimize the impacts of osteoarthritis of the knee. The amount of wedging required to induce a biomechanical response with clinical significance is still controversial. This study aimed to investigate the immediate biomechanical effects of different amounts of wedging in symptomatic medial knee OA. A 3D motion capture system and five force platforms were used to acquire walking kinematic and kinetic data along a 10 m walkway. Each participant was tested for six different lateral wedge insoles (0, 2, 4, 6, 8, and 10°) in a randomized order. Thirty-eight patients with medial osteoarthritis of the knee were recruited. The application of insoles resulted in an incremental reduction of the first peak of the external knee adduction moment under all experimental conditions in comparison with the control condition (0° insole). A significant increase (p < 0.05) was observed in peak ankle eversion and in ankle eversion at the first peak of the external knee adduction moment with insoles higher than 8° and 6°, respectively. Slight variations to lateral wedge insoles, greater than 2°, appear to induce significant biomechanical changes in patients with knee osteoarthritis.
