In order to study the biomechanical behavior of the ligaments around the knee joint (anterior cruciate ligament-ACL and medial collateral ligament-MCL), experiments were carried out using ten human amputated specimens. Specially designed small omega-shaped transducers were attached on the selected surface of the ligaments, and elongation of the ligaments were measured under valgus or anterior drawer stress in various flexion or rotation of the joint which was made by specific jig sets. The results showed that the load-elongation response varied depending on the sites of the ligaments and that the anterior instability caused by transection of the ACL gave definite effect on the strain behavior of the MCL and, vice versa, the medial instability caused by transection of the MCL gave considerable effect on that of the ACL. This experiment demonstrated a quantitative relationship between these ligaments which suggests the clinical importance of these ligaments for the knee joint stability.
为了研究膝关节周围韧带（前交叉韧带 - ACL和内侧副韧带 - MCL）的生物力学行为，使用10个人体截肢标本进行了实验。将专门设计的小ω形换能器附着在韧带的选定表面上，并在由特定夹具组施加的关节各种屈曲或旋转状态下的外翻或前抽屉应力作用下测量韧带的伸长情况。结果表明，载荷 - 伸长响应因韧带部位而异，并且ACL横断引起的前向不稳定对MCL的应变行为有明确影响，反之亦然，MCL横断引起的内侧不稳定对ACL的应变行为有相当大的影响。该实验证明了这些韧带之间的定量关系，这表明这些韧带对膝关节稳定性具有临床重要性。
