ACL Reconstruction - Remnant Preserving Technique -

Optimal treatment of the torn anterior cruciate ligament (ACL) remains controversial. The complexity of surgically reproducing the natural biomechanical and anatomical function of the ACL has led to a diversity of reconstructive procedures. Controversy continues to exist regarding the best reconstructive procedure for the ACL deficient knee, but currently, there is no ideal method. Because of the increased frequency of ACL injury and the functional impairment resulting from that, the role of mechanoreceptors in the ACL recently has attracted considerable attention. Proper reconstruction of the ruptured ACL does not always have good results. Success after operation may depend not only on the mechanical stability but also on the quality of recovery of proprioception. It is well known that most ACL are ruptured in proximal half and most mechanoreceptors have been reported to be located in the subsynovial layer and near the tibial insertion of the ACL. Expected roles of tibial remnant is to enhance the revascularization and cellular proliferation of the graft, to preserve proprioceptive function, and to be able to acquire anatomical placement of the graft without roof impingement. The remnant of the ruptured ACL has been removed to clearly visualize the ACL footprint or decrease the risk of impingement and Cyclops lesion in most current techniques for ACL reconstruction. Therefore it seems reasonable to assume that preserving the tibial remnant as much as possible as a source of reinnervation, if technically possible without causing impingement, would be of potential benefit to the patient. In addition, it will facilitate the vascular ingrowth and ligamentization of the grafted ACL.
