The knee is the weight-bearing joint most commonly affected by osteoarthritis. Bracing of the knee or the foot can be a useful nonoperative and nonpharmacologic treatment for persons with osteoarthritis that predominantly involves either the medial or lateral tibiofemoral compartment. The aim of wedged insoles and realigning knee braces is to reduce articular contact stress in the more involved tibiofemoral compartment. There is evidence that even knee sleeves that do not have an effect on alignment may confer symptomatic relief and enhance joint position sense. This review summarizes the current state of knowledge regarding the degree to which bracing at the knee or foot can effectively correct tibiofemoral malalignment, improve knee joint pain, and enhance physical function, and provides clinical recommendations for prescription of these devices to optimize effectiveness.
膝关节是负重关节中最常受骨关节炎影响的关节。对于主要涉及内侧或外侧胫股关节间隙的骨关节炎患者，膝关节或足部支具固定是一种有用的非手术和非药物治疗方法。楔形鞋垫和重新定位的膝关节支具的目的是减少受累胫股关节间隙的关节接触应力。有证据表明，即使对对线没有影响的膝关节套也可能带来症状缓解和增强关节位置感。这篇综述总结了目前关于支具在膝关节或足部固定能在多大程度上有效纠正胫股对线不良、改善膝关节疼痛和增强身体功能的知识，并为这些设备的处方提供了临床建议，以优化其效果。
