With the development of society, the incidence of ligament injuries due to traffic trauma and sports injuries, such as cruciate ligament injuries of the knee, Achilles tendon injuries and rotator cuff injuries, is increasing year by year. These structural injuries can lead directly to joint dysfunction, which in turn can lead to adjacent tissue damage and the development of degenerative joint disease. Ligaments in certain areas, such as the anterior cruciate ligament, are primarily repaired by scar filling after injury and are difficult to heal on their own, thus requiring replacement therapy. Surgically used replacements include allograft ligaments, allograft ligaments, autologous ligaments, and synthetic ligaments. Allograft substitutes have not received FDA approval due to occasional recurrent exudation, graft failure, and synovitis. The main problems with allografts are the tendency to cause chronic rejection reactions, prolonged healing time, and inappropriate ligamentization of the grafted tissue. Autologous grafts are a major limiting factor due to damage to healthy normal tissue, prolonged surgical time and frequent postoperative donor site anterior patellar pain, patellar tendon contracture, muscle atrophy, and tendonitis. Artificial ligaments, on the other hand, are gradually gaining popularity among experts because they do not damage or sacrifice autologous tissue, simplify surgery, are less traumatic, are easier to apply, and provide sufficient stability to the knee joint after surgery, with fast recovery.
