背景：由于膝关节形态是一个不可改变的前交叉韧带损伤危险因素，因此在损伤预防模型中对其的考虑是有限的。然而，膝关节解剖直接影响关节力学和潜在的伤害负荷。考虑到这一点，我们探讨了在着陆过程中表现出的关键膝关节解剖和三维生物力学参数之间的关系。我们假设胫骨外侧和内侧后坡及其比值、胫骨平台宽度、髁间距离及其比值与膝关节前反作用力、膝关节外展和内旋角度的峰值立场成正比。方法：20名年龄21.2（1.7）岁的娱乐活动女性在10次单腿着地切割任务中记录了站立阶段三维优势肢膝关节生物力学。通过一系列二维（矢状面、横切面和冠状面）磁共振图像对同一肢体的6个解剖指标进行量化。线性逐步回归分析检验了这些解剖因素中哪一个与三个基于受试者的平均膝关节峰值生物力学测量值独立相关。结果：胫骨外侧倾斜明显(P
Background: With knee morphology being a non-modifiable anterior cruciate ligament injury risk factor, its consideration within injury prevention models is limited. Knee anatomy, however, directly influences joint mechanics and the potential for injurious loads. With this in mind, we explored associations between key knee anatomical and three-dimensional biomechanical parameters exhibited during landings. We hypothesized that lateral and medial posterior tibial slopes and their ratio, and tibial plateau width, intercondylar distance and their ratio, were proportional to peak stance anterior knee joint reaction force, knee abduction and internal rotation angles.Methods: Twenty recreationally active females (21.2 (1.7) years) had stance phase three-dimensional dominant limb knee biomechanics recorded during ten single leg land-and-cut tasks. Six anatomical indices were quantified for the same limb via a series of two dimensional (sagittal, transverse and coronal) magnetic resonance images. Linear stepwise regression analyses examined which of these anatomical factors were independently associated with each of the three mean subject-based peak knee biomechanical measures.Findings: Lateral tibial slope was significantly (P
