膝关节受力在骨关节炎和膝关节置换术的生存和功能中是非常重要的。大量的研究试图估计在各种活动中膝关节周围的力量。已有几种方法用于将膝关节运动学和外力与关节内部接触力联系起来，最流行的是逆动力学、正动力学和静力体分析。膝关节受力也在膝关节置换术后的体内测量，这是对计算预测的有价值的验证。本综述总结了已发表的测量各种活动时膝关节受力的研究结果。分析了不同方法改变膝关节力分布的效果，如步态矫正、矫形器、助行器和定制跑步机。确定了我们目前的知识差距，并概述了该领域未来研究的方向。
Knee forces are highly significant in osteoarthritis and in the survival and function of knee arthroplasty. A large number of studies have attempted to estimate forces around the knee during various activities. Several approaches have been used to relate knee kinematics and external forces to internal joint contact forces, the most popular being inverse dynamics, forward dynamics, and static body analyses. Knee forces have also been measured in vivo after knee arthroplasty, which serves as valuable validation of computational predictions. This review summarizes the results of published studies that measured knee forces for various activities. The efficacy of various methods to alter knee force distribution, such as gait modification, orthotics, walking aids, and custom treadmills are analyzed. Current gaps in our knowledge are identified and directions for future research in this area are outlined.
