Preliminary Evaluation on Meniscal and Different Functional Splitting of Anterior Cruciate Ligament Injuries of Knee Joint in Rabbit Models

The diagnosis, treatment and efficacy evaluation of anterior cruciate ligament (ACL) partly jury is controversy. We established the models of different damage to functional bundle, which is used on the ACL of rabbit knee, and analyzed the impact of different damage to functional bundle on ACL. 45 New Zealand, white rabbits were randomly divided into three groups, anteromedial bundle (AMB) fracture group, posterolateral bundle (PLB) fracture group and no fracture group. When finishing building the models, 8 rabbits were killed randomly on the second, fourth and eighth week respectively. Finally, we can observe the general form of the meniscus through experimental HE staining. The two groups were similar to the general form. In addition, the surface was unsmooth in the HE staining experiment and the tissues were loose as well as collagen fibers of varying thickness. It is believed that it will cause meniscus regression along with the ruin of different functional bundle on the ACL.
