Abstract: Anterior cruciate ligament (ACL) is one of the most vulnerable structures during sports and an essential anterior stabilizing structure in the knee joint. ACL injury can impair a patient’s ability to move, and if not properly treated in time, it often results in serious adverse complications like meniscal and articular cartilage damage, and even traumatic osteoarthritis. Currently, ACL reconstruction is the standard treatment for ACL injury, and the choice of grafts has a significant impact on patients’ postoperative functional recovery and surgical success. Autografts are the most commonly used grafts and have the most stable efficacy, but they have drawbacks like limited sources and donor-site morbidity. Although having greater adaptability, allografts carry a risk of immune rejection and the spread of diseases. Artificial ligaments are appropriate for those who must quickly resume their athletic activities, but they are technically challenging and have not been shown to be long-term effective. Due to the numerous issues with traditional grafts, recent rapid advancements in tissue engineering techniques are generating novel ideas for ACL reconstruction. In order to aid in the treatment of ACL injury, this article discussed the benefits, drawbacks, and clinical effectiveness of different grafts used in ACL reconstruction.
