To determine the relationship between femoral-tibial morphometries and anterior cruciate ligament (ACL) pathologies using magnetic resonance imaging (MRI).
We retrospectively evaluated 455 patients (211 females and 244 males) who underwent knee MRI with suspected ACL pathology. Imaging findings were classified as normal ACL ( = 119), degeneration of the ACL ( = 116), partial ACL tear ( = 103), and complete ACL tear ( = 117). In all groups, the femoral intercondylar notch width (INW), intercondylar distance (CD), notch width index (NWI), and intercondylar notch angle (INA), the angles between the tibial plateau and tibial spines (MPA and LPA), intercondylar eminence peak angle (IEA), and tibial slope angles (MSA and LSA) were measured.
Femoral INW and NWI were significantly lower in patients with ACL pathology ( < 0.05). They were also lower in patients with tear compared to degeneration. The INA was significantly smaller in patients with ACL pathology ( < 0.001) and the significance continued in both genders. The LSA was only increased in patients with complete tear ( < 0.01) and the difference seems existing in both genders. It was also found that the LPA and IEA demonstrated significant increases in patients with ACL pathology ( < 0.01 and < 0.05, respectively) and the significance in LPA continued in both genders. Significant differences between males and females were found for the INW and CD in all 4 groups ( < 0.001). In addition, the INA, LPA and LSA were independent predictors in determining the risk of ACL pathology.
The ACL pathologies are associated with femoral-tibial morphometries and these associations exist in both genders.

使用磁共振成像（MRI）确定股骨 - 胫骨形态测量与前交叉韧带（ACL）病变之间的关系。
我们回顾性评估了455例疑似ACL病变而行膝关节MRI检查的患者（211例女性和244例男性）。影像表现分为正常ACL（n = 119）、ACL退变（n = 116）、ACL部分撕裂（n = 103）和ACL完全撕裂（n = 117）。在所有组中，测量股骨髁间窝宽度（INW）、髁间距离（CD）、髁间窝宽度指数（NWI）和髁间窝角度（INA），胫骨平台与胫骨棘之间的角度（MPA和LPA），髁间隆起峰值角度（IEA）以及胫骨坡度角（MSA和LSA）。
ACL病变患者的股骨INW和NWI显著更低（P < 0.05）。与退变患者相比，撕裂患者的这些指标也更低。ACL病变患者的INA显著更小（P < 0.001），且在两性中均有显著性差异。LSA仅在完全撕裂患者中增加（P < 0.01），且在两性中似乎均存在差异。还发现ACL病变患者的LPA和IEA显著增加（分别为P < 0.01和P < 0.05），且LPA在两性中均有显著性差异。在所有4组中，男性和女性的INW和CD存在显著差异（P < 0.001）。此外，INA、LPA和LSA是确定ACL病变风险的独立预测因素。
ACL病变与股骨 - 胫骨形态测量相关，且这些关联在两性中均存在。
