Biomechanical study of the ankle-hindfoot complex using robotic system

本研究的目的是利用尸体标本来评估踝关节外侧韧带的力学特性以及完整和韧带不足的踝关节模型的运动学。使用由定制的6轴机械手和6-DOF通用力/力矩传感器组成的6-DOF机器人系统。本研究为踝关节外侧韧带的损伤机制和重建手术提供了重要的基础资料。该信息适用于重建手术期间踝关节位置和移植物张力的决定，这将有助于改善踝关节外侧韧带损伤手术治疗后的结局。

The purpose of this study was to evaluate mechanical property of the lateral ligament of the ankle and kinematics of the intact and ligament insufficient ankle model using cadaveric specimens. A 6-DOF robotic system consisting of a custom made 6-axis manipulator with a 6-DOF universal force/moment sensor was used. This study provided important baseline information such as injury mechanism or reconstruction surgeries of the ankle lateral ligament. This information is applicable for decision of the ankle position and tension of the graft during reconstructive surgeries, which will contribute improvement of outcome following surgical treatment of the lateral ligament injury of the ankle joint.
