Abstract

Background The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) are important structures to maintain knee stability. The present study aimed to further enrich understandings of the morphology of the cruciate ligaments and explore the relationship between the diameter of ACL and PCL. Method This study collected valid MRI samples of 50 male and 50 female normal right knee joints and measured the diameter of each point of the ACL and PCL through the 3D Slicer. Results The diameter of the ACL in the sagittal MRI of the normal right knee joint was significantly different from the diameter of each point of the PCL. The average diameter of each point of the ACL was larger than the diameter of the corresponding point of the PCL. Males and females had statistical differences in their PCL origin point, PCL midpoint, ACL origin point, ACL midpoint, and ACL insertion point diameters under sagittal MRI examination. The average diameter of males was greater than the average diameter of females at the above corresponding sites. In sagittal MRI scans of the normal right knee joint, we observed that only the origin point of the PCL exhibited a moderate correlation with the midpoint and insertion point of the ACL in terms of their respective diameters. Conclusion The correlation between diameters of normal ACL and PCL in knee joint MRI was moderate and may help clinicians determine appropriate graft for cruciate ligament reconstruction surgery quickly for severe cruciate ligament injuries.

十字韧带的比较形态:放射学研究
背景 前交叉韧带(ACL)和后交叉韧带(PCL)是维持膝关节稳定性的重要结构。本研究旨在进一步丰富对交叉韧带形态的认识,并探讨前交叉韧带和后交叉韧带直径之间的关系。方法 本研究收集了 50 名男性和 50 名女性正常右膝关节的有效核磁共振样本,并通过 3D Slicer 测量了前交叉韧带和 PCL 各点的直径。结果 在正常右膝关节的矢状磁共振成像中,前交叉韧带的直径与 PCL 各点的直径存在显著差异。前交叉韧带各点的平均直径大于 PCL 相应点的直径。在矢状磁共振成像检查中,男性和女性的 PCL 起点、PCL 中点、前交叉韧带起点、前交叉韧带中点和前交叉韧带插入点直径存在统计学差异。在上述相应部位,男性的平均直径大于女性。在正常右膝关节的矢状磁共振成像扫描中,我们观察到只有 PCL 起点与前交叉韧带中点和插入点的直径呈中度相关。结论 膝关节核磁共振成像中正常前交叉韧带和 PCL 的直径之间存在中度相关性,可帮助临床医生快速确定严重交叉韧带损伤的十字韧带重建手术的合适移植物。
