The anterior cruciate ligament (ACL) consists of two anatomic and functional bundles, the anteromedial and posterolateral bundle. Depending on the mechanism of injury, there are different injury patterns, demonstrating a wide spectrum of partial ACL tears. Single bundle partial ACL tears can be treated with augmentation. Theoretically, sparing the intact parts of the ACL may increase vascularization and proprioception and may result in better stability and improved clinical outcome for the patient. In this article, we review the anatomy and function of ACL bundles and demonstrate cases of single bundle ACL tear with subsequent augmentation.
前交叉韧带（ACL）由两个解剖和功能束组成，前内侧束和后外侧束。根据损伤机制的不同，ACL 有不同的损伤模式，表现为广泛的部分 ACL 撕裂。单束部分 ACL 撕裂可以采用增强治疗。理论上，保留 ACL 的完整部分可能会增加血管生成和本体感觉，并可能为患者带来更好的稳定性和临床效果。本文回顾了 ACL 束的解剖和功能，并展示了单束 ACL 撕裂后进行增强治疗的病例。
