The anterior cruciate ligament: a technique of repair and reconstruction

Both primary repair and late substitution of anterior cruciate ligaments can be accomplished by intra-articular methods. This principle is to provide temporary struts that are initially avascular but can later undergo revascularization and metaplasia to form a new ligament. The graft does afford initial support, however. An understanding of anatomic principles, suture placement, freedom of graft from impingement, avoidance of acute angular deviation of the graft, solid static stability, anatomic attachment points, and blood supply, is absolutely essential for success in this field of surgery.
