The techniques that have been used to characterize the biomechanical behavior of the knee, cruciate ligaments, and cruciate ligament replacements differ, making comparisons between studies difficult or, at times, impossible. Therefore, it is important to standardize the testing protocols and techniques that describe the biomechanical behavior of the knee and cruciate ligaments. This will allow investigators to express opinions with respect to the interpretation of data, rather than based on differences between testing techniques. Standardized techniques are proposed to locate the origins of the tibial and femoral coordinate systems, and thus, allow comparisons of knee kinematics (e.g., displacements and rotations) between investigations. Standard techniques that can be used to measure the load-displacement behavior of the knee are described, and important considerations that should be appreciated with respect to preparing and testing of the joint are summarized. It is important to evaluate the single cycle load-to-failure characteristics and the cyclic loading response of an anterior cruciate ligament graft, and techniques to evaluate cruciate ligament graft fixation are proposed. The strengths of different models to characterize the biomechanical behavior of the knee are reviewed.
用于描述膝关节、交叉韧带及交叉韧带替代物生物力学行为的技术各不相同，这使得不同研究之间的比较变得困难，有时甚至无法进行。因此，规范描述膝关节和交叉韧带生物力学行为的测试方案和技术非常重要。这将使研究人员能够基于数据解读发表观点，而非基于测试技术之间的差异。本文提出了标准化技术来确定胫骨和股骨坐标系的原点，从而实现不同研究之间膝关节运动学（如位移和旋转）的比较。文中描述了可用于测量膝关节载荷-位移行为的标准技术，并总结了在关节准备和测试方面应予以重视的重要注意事项。评估前交叉韧带移植物的单周期失效载荷特性和循环加载响应非常重要，文中还提出了评估交叉韧带移植物固定的技术。本文回顾了用于描述膝关节生物力学行为的不同模型的优点。
