An apparatus and experimental technique have been developed which allow the simultaneous quantitation of human cadaver knee ligament forces with the knee in various positions and subjected to various loads. The methodology permits all the major ligaments of the knee to be kept intact, thus preserving much of their normal relative load-bearing function. A novel measurement technique was employed for ligament force measurement. Strain gauges were placed at the ligamentous insertions and origins either on cortical bone or the cancellous/cortical transition. Gauge output was subsequently calibrated quantitatively by cutting the ligaments and subjecting them to known loads. The gauging technique was thermally stable, and the method as a whole yielded reproducible relative ligament force data when knee positions and loads were repeated for a given knee specimen. Three fresh human cadaver knee specimens have been subjected to testing thus far with gauges at six ligamentous sites. Initial evaluation of the data indicate that ligamentous loading patterns were quite different from those reported in the literature as determined by other methods.
已经开发出一种装置和实验技术，可在膝关节处于不同位置并承受各种负荷时同时对人体尸体膝关节韧带力进行定量分析。该方法能使膝关节的所有主要韧带保持完整，从而保留其大部分正常的相对承重功能。采用了一种新颖的测量技术来测量韧带力。应变片被放置在韧带在皮质骨上的附着点和起点处，或者松质骨/皮质骨交界处。随后通过切断韧带并使其承受已知负荷来对应变片输出进行定量校准。该测量技术具有热稳定性，并且当对给定的膝关节标本重复膝关节位置和负荷时，整个方法能得出可重复的相对韧带力数据。到目前为止，已经对三个新鲜的人体尸体膝关节标本在六个韧带部位使用应变片进行了测试。对数据的初步评估表明，韧带加载模式与文献中通过其他方法确定的模式有很大不同。
