Abstract

A histological and biomechanical study of anterior cruciate ligament (ACL) reconstruction using the iliotibial tract (ITT) was carried out in rabbits. Sixty-five young adult male rabbits were used for the experiments. In the histological study, 3 weeks after the substitution, specimens, showed acellular changes, and cellular repopulation was noted from the peripheral area at 6 weeks. At 24 weeks, the original spindle-shaped fibroblasts of the substitute had changed to round cells. The ligament bone junction was formed by 48 weeks and its structure was similar to that of a normal junction. Transmission electron microscopic examination showed collagen fibril distribution in each test group. The 12-week specimens had fibrils of small diameter only, but some 24-week specimens showed a biphasic appearance, like the ACL, which has both large and small fibrils. On mechanical testing, the maximal load was decreased until 18 weeks, and then recovered to 50% of that of the normal ACL at 48 weeks, this value being approximately the same as that of the ITT used in the reconstruction.
