膝关节骨性关节炎步态分析特征及3D矫形鞋垫设计应用

 概述了2种步态分析实验系统、实验原理和KOA患者下肢三维步态的改变；由于下肢生物力学的复杂性和研究技术的局限性，3D矫形鞋垫设计目前仍处于初级阶段，产品的治疗效果尚无统一意见并且未大量生产使用，因此对3D矫形鞋垫在KOA中的应用原理及制作过程进行深入探讨，明确KOA患者膝关节周围动力和静力结构变化，将其应用于3D矫形鞋垫的设计和生产，为早期KOA保守治疗提供重要解决方案，既能够患者满足舒适性和功能性的双重需求，又能使制造周期和成本显著降低。

Application of orthotic devices in the knee osteoarthritis and its effect on lower limb gait

The lower limb gait analysis is an effective method to quantitatively analyze the biomechanical changes of the internal motion of the knee joint, as well as an effective way to study the occurrence, the development and the intervention of the knee osteoarthritis (KOA). Two kinds of gait analysis experimental systems and their principles are reviewed, as well as the changes of the KOA patients' 3D lower limb gait. Due to the complexity of the lower limb biomechanics and the limitations of the research technology, the technique of the 3D orthopedic insoles is still in the preliminary stage, and there is no consensus with respect to the therapeutic effect of the products, and they have not been mass-produced and used. Therefore, the application principle and the manufacture process of the 3D orthopaedic insoles in the KOA are emphatically discussed. The dynamic and static structures and the changes around the knee joint of patients with the KOA, as being widely used in the design and the production of the 3D orthopaedic insoles, provide an important solution for the early conservative treatment of the KOA. And it can not only meet the dual requirements of comfort and functionality for patients, but also significantly reduce the manufacturing cycle and cost.
