This paper describes a novel modeling technique for simulating the motion of the knee joint in three dimensions. For a given range of flexion, the envelope of passive knee joint motion is determined by applying additional translations and rotations necessary to maintain Force Balance in the joint. An initial application of this Force Balance technique has been implemented in MATLAB on a Sparc 10. Results of this application, which describes the knee's motion in the sagittal plane based on the ACL, PCL, MCL, and LCL, are presented here. This model is applicable to the analysis of ligament loss, damage, and repair, and can be adapted to include muscle forces in order to simulate joint motion under load.
本文描述了一种用于三维模拟膝关节运动的新型建模技术。对于给定的屈曲范围，通过施加维持关节力平衡所需的额外平移和旋转来确定被动膝关节运动的包络线。这种力平衡技术的初步应用已在Sparc 10上的MATLAB中实现。这里展示了该应用的结果，该结果基于前交叉韧带（ACL）、后交叉韧带（PCL）、内侧副韧带（MCL）和外侧副韧带（LCL）描述了膝关节在矢状面内的运动。该模型适用于韧带损失、损伤和修复的分析，并且可以进行调整以纳入肌肉力量，从而模拟负载下的关节运动。
