Abstract:

Anterior cruciate ligament (ACL) injury is caused by strong violence, which can destabilize the knee joint, cause joint cartilage degeneration, meniscus injury, and in severe cases, develop osteoarthropathy. The gold standard for the treatment of ACLR injuries at this stage is arthroscopic anterior cruciate ligament reconstruction (ACLR).In clinical practice, the LARS (Ligament advanced reinforcement system) artificial ligament made of polyethylene terephthalate (PET) as the material has a good effect in the short and medium term, but the long-term biological healing between the graft and the host bone is poor, and the real "ligamentization" requirement of the postoperative graft cannot be met. Coating-modified modification of artificial ligaments can improve their hydrophilicity and biocompatibility, which in turn can promote the healing of graft-bone tunnels. Tendon bone healing is a bone-derived progressive process from indirect insertion to direct insertion, which takes a relatively long time and is closely related to the prognosis and early rehabilitation effect of patients. This article reviews the progress of superficial modification of artificial ligaments to promote ACLR tendon bone healing.

Key words: anterior cruciate ligament, surgical reconstruction, artificial ligament, superficial modification, tendon bone healing
