Determination of ligament forces is an integral part of understanding their contribution during motion and external loading of an intact joint. While almost all previous investigations have reported only the magnitude of tension, this alone cannot adequately describe the function of a particular ligament. An alternative approach to determine the in-situ forces in ligaments has been developed which utilizes a universal force-moment sensor in conjunction with a force transformation scheme. In addition to providing the magnitude of ligament force, the direction and point of application of this in-situ force can also be determined. Further, the approach does not require mechanical contact with the ligament. Application of this new methodology is demonstrated for the human anterior cruciate ligament in the present study (n = 7) although it may be similarly applied to other ligaments at the knee or in other synovial joints of the human body.
确定韧带力是理解其在完整关节运动和外部负荷过程中所起作用的一个不可或缺的部分。虽然几乎所有先前的研究都只报告了张力的大小，但仅此一点并不能充分描述特定韧带的功能。一种确定韧带原位力的替代方法已经开发出来，该方法利用通用力 - 力矩传感器结合力转换方案。除了提供韧带力的大小外，还可以确定这种原位力的方向和作用点。此外，该方法不需要与韧带进行机械接触。在本研究（n = 7）中展示了这种新方法在人体前交叉韧带中的应用，尽管它可能同样适用于膝关节或人体其他滑膜关节的其他韧带。
