This study evaluates the amplitude of the anatomical-mechanical angle (AMA-angle) using 4 measuring methods of the tibial distal anatomical axes (DAA) previously described, comparing the literature results to determine if there are significant differences in patients with cranial cruciate ligament (CrCL) rupture.
This study was comprised of 30 tibiae (29 dogs), including 1 bilateral case.
A retrospective study was selected for this research. DAA measurements were performed on all surgically confirmed cases of canine CrCL rupture at Hospital Veterinário de Especialidades Bruselas from 2019 to 2022. Four different published methods (identified by surname of the corresponding author of the original publication) were compared. Tibial measurements were made using Veterinary Preoperative Orthopedic Planning Pro software (https://vpop-pro.com/) on mediolateral radiographic projections obtained from a digital database.
The mean (range) in the DAA method conducted by Hulse obtained a AMA-angle of 5.4° (3.3 to 8.1°), 3.0° (0 to 5.8°) for Osmond et al, 3.2° (0.9 to 6°) for Miles, and 5.9° (2.4 to 8.8°) for Tudury. Differences among the means of the AMA-angle of the authors methods were found with a statistical difference (P < .05), except between Osmond and Miles. The mean AMA-angle with the Osmond method concurred with previous study results that determined the magnitude using the same measurement method of DAA in patients with CrCL rupture.
The AMA-angle magnitude has been associated with higher sensitivity and specificity for predicting the development of CrCL rupture compared to other anatomical factors evaluated; therefore, future comparisons with different methods of measurement of the DAA between healthy and affected patients are recommended to determine whether any of them can increase the percentage value as a predictive factor for the occurrence of this condition.
本研究通过 4 种先前描述的胫骨远端解剖轴（DAA）测量方法评估解剖力学角度（AMA 角），并与文献结果进行比较，以确定是否存在前十字韧带（CrCL）断裂患者之间存在显著差异。
本研究包括 30 个胫骨（29 只狗），包括 1 例双侧病例。
选择回顾性研究进行本研究。2019 年至 2022 年，在布鲁塞尔兽医专科医院对所有经手术证实的犬 CrCL 断裂病例进行了 DAA 测量。比较了 4 种不同的已发表方法（通过原始出版物的对应作者的姓氏识别）。使用 Veterinary Preoperative Orthopedic Planning Pro 软件（https://vpop-pro.com/）在从数字数据库获得的外侧-内侧放射摄影投影上进行胫骨测量。
Hulse 进行的 DAA 方法的平均值（范围）为 5.4°（3.3 至 8.1°），Osmond 等人的 3.0°（0 至 5.8°），Miles 的 3.2°（0.9 至 6°）和 Tudury 的 5.9°（2.4 至 8.8°）。除了 Osmond 和 Miles 之间，作者方法的 AMA 角平均值之间存在统计学差异（P <.05）。Osmond 方法的平均 AMA 角与先前使用相同 DAA 测量方法确定 CrCL 断裂患者大小的研究结果一致。
与评估的其他解剖因素相比，AMA 角的大小与 CrCL 断裂的发生具有更高的敏感性和特异性；因此，建议在健康和受影响的患者之间进行不同的 DAA 测量方法的未来比较，以确定它们中的任何一种是否可以增加作为预测该疾病发生的预测因子的百分比值。
