Individual variations in the anatomy of the knee joint have been suggested to affect the ability to functionally compensate for ACL insufficiency or to put an individual at an increased risk of ACL injury. These variations include the posterior tibial slope, the concavity of the medial tibial plateau, the convexity of the lateral tibial plateau, and the configuration of the femoral condyles.
This anatomical study investigates if there is a correlation between the individual surface geometry of the femorotibial joint and the morphometry of the ACL. These data were assumed to provide evidence whether or not the functional stability of an ACL-insufficient knee may be derived from its radiographic surface geometry. Standardised measurement techniques were used to analyse the surface geometry of 68 human cadaver knees. Data were correlated with the cross-sectional area, the area of insertion and position of the footprint of the ACL and its functional bundles.
Analysis revealed that there was a significant, but weak correlation between the femoral and tibial area of ACL insertion and the depth of the medial and lateral femoral condyle. No correlation was found between the surface geometry of the femorotibial joint and the cross-sectional area of the ACL. The results of this anatomical study suggest that the relationship between the joint surfaces and the morphometry of the ACL primarily is a function of size of the knee joint.
Based on our results, there is no evidence that the stability of the knee can be derived from its radiographic surface geometry.
膝关节解剖结构的个体差异被认为会影响功能性地代偿 ACL 不足的能力，或增加 ACL 损伤的风险。这些差异包括胫骨后倾角、内侧胫骨平台的凹陷度、外侧胫骨平台的凸起度以及股骨髁的形态。
本解剖学研究调查了髌股关节的个体表面几何形状与 ACL 形态之间是否存在相关性。这些数据被认为可以提供证据，证明 ACL 不足的膝关节的功能稳定性是否可以源自其影像学表面几何形状。使用标准化的测量技术分析了 68 个人体尸体膝关节的表面几何形状。数据与 ACL 的横截面面积、插入面积和止点位置及其功能束相关联。
分析显示，ACL 插入的股骨和胫骨面积与内外侧股骨髁的深度之间存在显著但较弱的相关性。髌股关节的表面几何形状与 ACL 的横截面积之间没有相关性。本解剖学研究的结果表明，关节表面与 ACL 形态之间的关系主要是膝关节大小的函数。
根据我们的结果，没有证据表明膝关节的稳定性可以源自其影像学表面几何形状。
