To evaluate whether anthropometric data can predict anterior cruciate ligament (ACL) sizes on magneti resonance imaging (MRI) in Asian population.
Reconstruction of ACL has been performed over a decade ago. Recently, more individualized ACL reconstruction is performed taking account of each patient's ACL characteristics. However, there has been limited study regarding ACL sizes in Asian Indonesian population. This study aimed to evaluate the role of anthropometric data in ACL sizes using MRI in Asian Indonesian population.
Retrospective Study.
A series of 531 knees from 420 patients with knee pain and intact ACL confirmed by MRI study. Length, width and inclination angle of ACL were measured using a T2-weighted sagittal MRI 3.0 Tesla Magnetom Skyra. Height, weight, body mass index (BMI) and age were recorded. Multiple regression analysis was used to determine relationship between the anthropometric data and size of ACL measurements.
ACL length and width were significantly different between male and female, consecutively. Mean ACL length was 35.36 ± 3.63 mm, male was significantly longer (36.59 ± 3.24 mm) compared to female (32.77 ± 2.99 mm), p < 0.0001. Mean ACL width was 10.23 ± 1.84 mm, male was significantly wider (10.85 ± 1.59 mm) compared to female (8.93 ± 1.64 mm), p < 0.0001. The mean ACL inclination angle was 47.75° ± 3.07° (range 40.17°-57.12°). The strongest correlation for ACL length was height and weight (r = 0.437; r = 0.341 consecutively, p < 0.0001). Females had stronger correlation compared to males for ACL length (R = 0.489 vs R = 0.418). ACL width showed weak correlation with anthropometric data. The following regression analysis equation was obtained for ACL length: ACL length = 60.697 - 0.11age + 0.461weight (kg) - 16.522height (meter) - 1.093BMI (R = 0.539; p < 0.0001).
Anthropometric data can be utilized as a predictor of ACL length in Asian Indonesian population. The ACL length in Asian Indonesian population is shorter than that in Western population study.
评估亚洲人群的人体测量学数据能否预测前交叉韧带（ACL）在磁共振成像（MRI）上的大小。
ACL 的重建已经进行了十多年。最近，根据每个患者的 ACL 特征，进行了更多的个体化 ACL 重建。然而，关于亚洲印度尼西亚人群 ACL 大小的研究有限。本研究旨在评估亚洲印度尼西亚人群中，MRI 上的 ACL 大小与人体测量学数据的关系。
回顾性研究。
对 420 名膝关节疼痛且 ACL 经 MRI 检查证实完整的患者的 531 个膝关节进行了一系列研究。使用 3.0T Magnetom Skyra T2 加权矢状位 MRI 测量 ACL 的长度、宽度和倾斜角度。记录身高、体重、体重指数（BMI）和年龄。使用多元回归分析确定人体测量学数据与 ACL 测量值之间的关系。
ACL 的长度和宽度在男性和女性之间存在显著差异。男性 ACL 的平均长度为 35.36 ± 3.63mm，明显长于女性（32.77 ± 2.99mm），p<0.0001。男性 ACL 的平均宽度为 10.23 ± 1.84mm，明显宽于女性（8.93 ± 1.64mm），p<0.0001。ACL 的平均倾斜角度为 47.75°±3.07°（范围为 40.17°-57.12°）。ACL 长度与身高和体重的相关性最强（r=0.437；r=0.341，均为 p<0.0001）。与男性相比，女性的 ACL 长度相关性更强（R=0.489 与 R=0.418）。ACL 宽度与人体测量学数据的相关性较弱。得到以下 ACL 长度的回归分析方程：ACL 长度=60.697-0.11年龄+0.461体重（kg）-16.522身高（米）-1.093BMI（R=0.539；p<0.0001）。
亚洲印度尼西亚人群的人体测量学数据可用于预测 ACL 长度。亚洲印度尼西亚人群的 ACL 长度比西方人群的短。
