Abstract
The completely torn ACL is both biologically challenged (due to the lack of provisional scaffold formation) and mechanically challenged (due to the difficulty in suturing fibrous tissue ends together). To help decouple the challenges and allow us to first focus on the biologic problem, we needed an in vivo partial ACL tear model. One such model was developed in collaboration with Kurt Spindler at Vanderbilt University. In this model, the central fibers of the ACL are cut, but the fibers on either side of the defect are left intact, thus providing optimal mechanical stability of the defect. Using this model, we were able to demonstrate that the use of a collagen-platelet composite could stimulate biologic and functional healing of a partial ACL defect. The next chapter will then add in the mechanical challenges of a complete ACL tear.
