Tensile tests for fascicles, fascicle bundles and bone-ligament-bone units (BLB) all from swine Anterior Cruciate Ligament (ACL) and Posterior Cruciate Ligament (PCL) respectively were performed to compare the'results with each other. Two stress-strain curves of fascicles were derived. One was derived using the cross-sectional area at no load (Group N) and the other was done using the cross-sectional area at initial load (Group I). A stress-strain curve of fascicle bundles was derived using the cross-sectional area at no load. The results from the ACL showed that the tangent modulus of fascicle (Group I) was almost equal to that of BLB while that Group N was significantly low, indicating that ligaments may be constituted of tensed fascicles. While the results from the PCL showed that the tangent modulus of the Group I were significantly lower than that of the BLB. Thus microscopic observations were performed to gain insight into the structural difference between the ACL and the PCL.
