[Anatomical study of anterior cruciate ligament and its effect on reconstruction technique].

To summarize the current research progress of anterior cruciate ligament (ACL) anatomy, and discuss its effect on the reconstruction technique.The literature concerning ACL anatomy and reconstruction at home and abroad was extensively reviewed and summarized.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.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.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。.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。.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。.“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。.
