本研究旨在比较慢性踝关节不稳（CAI）患者和健康志愿者的距腓前韧带（ATFL）和距腓后韧带（PTFL）角度的差异，确认ATFL-PTFL角度是否可以作为CAI的可靠评估方法，以提高临床诊断的准确性和特异度。这项回顾性研究包括 240 名参与者：2015 年至 2021 年间的 120 名 CAI 患者和 120 名健康志愿者。通过 MRI 横断面仰卧位测量两组踝关节区域的 ATFL-PTFL 角度。参与者接受全面的MRI扫描后，将ATFL-PTFL角度作为ATFL损伤患者和健康志愿者的主要指标进行比较，并由经验丰富的肌肉骨骼放射科医生进行测量。此外，MRI还纳入了涉及AFTL解剖形态特征的其他定性和定量指标，如ATFL的长度、宽度、厚度、形状、连续性和信号强度，可作为辅助指标。 CAI组的ATFL-PTFL角为90.8°±5.7°，与非CAI组的ATFL-PTFL角80.0°±3.7°有显着差异（p<0.001）。至于ATFL-MRI特征，CAI组的长度（p = 0.003）、宽度（p < 0.001）和厚度（p < 0.001）也与非CAI组有显着差异。 CAI组90%以上的患者ATFL损伤，形状不规则、不连续、信号强度高或混合。与健康人相比，大多数CAI患者的ATFL-PTFL角度较大，可作为诊断CAI的辅助指标。然而，ATFL的MRI特征变化可能与ATFL-PTFL角度的增加无关。
This study intended to compare the difference between the anterior talofibular ligament (ATFL) and posterior talofibular ligament (PTFL) angle with chronic ankle instability (CAI) patients and healthy volunteers, and to confirm whether using the ATFL–PTFL angle could be a reliable assessment method for CAI, so as to improve the accuracy and specificity of clinical diagnosis. This retrospective study included 240 participants: 120 CAI patients and 120 healthy volunteers between 2015 and 2021. The ATFL–PTFL angle of the ankle region was gaged in the cross-sectional supine position on MRI between two groups. After participants undergoing a comprehensive MRI scanning, ATFL–PTFL angles were regarded as the main indicator of patients with the injured ATFLs and healthy volunteers to compare, and were measured by an experienced musculoskeletal radiologist. Moreover, other qualitative and quantitative indicators referring to anatomical and morphological characteristics of the AFTL were included in this study with MRI, such as the length, width, thickness, shape, continuity, and signal intensity of the ATFL, which can be used as secondary indicators. In the CAI group, the ATFL–PTFL angle was 90.8° ± 5.7°, which was significantly different from the non-CAI group where the ATFL–PTFL angle for 80.0° ± 3.7° (p < 0.001). As for the ATFL-MRI characteristics, the length (p = 0.003), width (p < 0.001), and thickness (p < 0.001) in the CAI group were also significantly different from the non-CAI group. Over 90% of the cases, patients of the CAI group had injured ATFL with an irregular shape, non-continuous, and high or mixed signal intensity. Compared with healthy people, the ATFL–PTFL angle of most CAI patients is larger, which can be used as a secondary index to diagnose CAI. However, the MRI characteristic changes of ATFL may not relate to the increased ATFL–PTFL angle.
