Recent studies have demonstrated that skeletally immature athletes with an ACL injury may require surgical reconstruction if they return to high-demand sports. This study used MRI to compare the anatomy of the ACL in skeletally immature and adult subjects. Measurements were recorded in the sagittal plane for the anterior-posterior dimension of the proximal tibia, and the anterior, center, and posterior limits of the ACL, and the roof inclination angle of the femur. These values were compared to established reference values for adult knee anatomy. In skeletally immature women ( n=7) the ACL anterior limit, center and posterior limit, and roof inclination angle were 28%, 46%, 63%, and 38 degrees, respectively, compared to 28%, 44%, 60%, and 35 degrees in adult women. In skeletally immature men ( n=15) the ACL anterior limit, center, posterior limit, and roof inclination angle were 27%, 43%, 59%, and 40 degrees, respectively, compared to 28%, 44%, 59%, and 37 degrees in adult men. In the younger subjects the overall dimensions of the proximal tibia were smaller than that in adults, but the anatomical landmarks for the ACL were proportional. If ACL reconstruction is performed in skeletally immature subjects, the smaller dimensions of the tibia need to be considered, and the use of anatomical landmarks is an important factor in graft placement
近期研究表明，骨骼未成熟的运动员若ACL损伤且要重返高需求运动项目，可能需要进行手术重建。本研究使用MRI比较骨骼未成熟和成年受试者的ACL解剖结构。在矢状面记录近端胫骨的前后尺寸、ACL的前、中、后界限以及股骨的髁间窝倾斜角。将这些值与成年膝关节解剖结构的既定参考值进行比较。在骨骼未成熟女性（n = 7）中，ACL前界限、中心和后界限以及髁间窝倾斜角分别为28°、46°、63°和38°，而成年女性分别为28°、44°、60°和35°。在骨骼未成熟男性（n = 15）中，ACL前界限、中心、后界限以及髁间窝倾斜角分别为27°、43°、59°和40°，而成年男性分别为28°、44°、59°和37°。在较年轻的受试者中，近端胫骨的整体尺寸小于成年人，但ACL的解剖标志是成比例的。如果对骨骼未成熟的受试者进行ACL重建，需要考虑胫骨较小的尺寸，并且使用解剖标志是移植物放置的一个重要因素
