The aim of this study was to obtain geometric data of in vivo patellar ligament (PL) and anterior cruciate ligament (ACL) by MRI and to analyze the correlation of the two with body weight, height and gender. A total of 157 cases with normal sagittal images of bilateral PL and ACL were enrolled. The PL and ACL lengths in the images were measured using the Radworks 5.1 application. The intraclass correlation coefficient for the data measured independently by three doctors was 0.997-1.000. In individuals aged 15-24 years, the values of PL and ACL length and the PL to ACL ratio were 43.95±4.25 mm, 38.45±4.62 mm and 1.15±1.09 in males and 42.03±0.94 mm, 36.00±1.06 mm and 1.18±0.1 in females, respectively. In individuals aged 25-64 years, the values in males were 40.99±4.45 mm, 36.06±3.74 mm and 1.14±0.09 and in females were 39.84±0.64 mm, 36.50±0.81 mm and 1.11±0.02, respectively. In individuals aged ≥65 years, the values in males were 41.43±3.08 mm, 36.62±3.44 mm and 1.15±0.09 and in females were 38.94±0.79 mm, 34.36±0.85 mm and 1.13±0.07, respectively. There was a significant difference between PL and ACL length on the same side (P<0.01). The data obtained was stable and repeatable. The present study established a database of PL and ACL length and the ratio of the two measured by MRI.
本研究的目的是通过磁共振成像（MRI）获取体内髌韧带（PL）和前交叉韧带（ACL）的几何数据，并分析二者与体重、身高和性别的相关性。共纳入157例双侧PL和ACL矢状位图像正常的病例。使用Radworks 5.1应用程序测量图像中PL和ACL的长度。三位医生独立测量数据的组内相关系数为0.997 - 1.000。在15 - 24岁个体中，男性的PL和ACL长度值以及PL与ACL比值分别为43.95±4.25 mm、38.45±4.62 mm和1.15±1.09，女性分别为42.03±0.94 mm、36.00±1.06 mm和1.18±0.1。在25 - 64岁个体中，男性的值为40.99±4.45 mm、36.06±3.74 mm和1.14±0.09，女性分别为39.84±0.64 mm、36.50±0.81 mm和1.11±0.02。在≥65岁个体中，男性的值为41.43±3.08 mm、36.62±3.44 mm和1.15±0.09，女性分别为38.94±0.79 mm、34.36±0.85 mm和1.13±0.07。同侧PL和ACL长度之间存在显著差异（P<0.01）。所获得的数据稳定且可重复。本研究建立了通过MRI测量的PL和ACL长度以及二者比值的数据库。
