Objective: To summarize the current research progress of anterior cruciate ligament (ACL) anatomy, and discuss its effect on the reconstruction technique.
Methods: The literature concerning ACL anatomy and reconstruction at home and abroad was extensively reviewed and summarized.
Results: The anatomy and morphology of ACL has gained new recognition in recent years, and the "Ribbon-like" ACL has gradually been paid attention to by researchers. In present researches, it seems the "Ribbon-like" anatomy theory has advantages in theory when compared with the previous anatomy theory. It is more in line with the anatomy and isometric reconstruction.
Conclusion: The understanding of ACL anatomy guided the development of ACL reconstruction. The "Ribbon-like" ACL anatomy theory is the different understanding of the anatomy theory, which remains controversy. The "Ribbon-like" reconstruction maybe has more advantages in theory, but further study is needed.
目的: 对前交叉韧带（anterior cruciate ligament，ACL）解剖研究进展以及对于 ACL 重建技术的影响进行总结。.
方法: 广泛查阅国内外有关 ACL 解剖和重建的研究文献，并进行总结分析。.
结果: 近年 ACL 的解剖和形态有了新认识，提出的扁平的、如带状（Ribbon-like）的 ACL 解剖理论逐渐被关注。目前研究认为相对于既往重建方式，“Ribbon-like”ACL 解剖重建在理论上具有优越性，更符合解剖重建、等长重建。.
结论: “Ribbon-like” ACL 解剖理论是对 ACL 解剖结构的不同认识，但存在争议，且缺少临床应用，需要进一步研究。.
