The anterior talofibular ligament and the calcaneofibular ligament were sonographically investigated in 16 patients with functional ankle instability (FAI) and 16 controls under neutral and standardized stress conditions of 15 kp with a TELOS device. Clinical investigation revealed a significantly higher rate of a positive anterior drawer and talar tilt (p <0.001, respectively), significantly increased supination (p = 0.047) of the right ankle joint and increased plantarflexion (p = 0.009) of the left ankle joint in the FAI group compared with controls. Significantly higher rates of inhomogeneity and hypo-echogenicity were sonographically observed in both ligaments in the FAI group (p < 0.05, respectively). The anterior talofibular ligament was significantly longer under stress conditions, and the calcaneofibular ligament was significantly longer under both neutral and stress conditions in the FAI group (p < 0.05, respectively). Peritendinous edema of the peroneal tendons was found in 22% of the FAI group and 6% of controls.
在 16 例功能性踝关节不稳（FAI）患者和 16 例对照者中，使用 TELOS 设备在中立和 15 kp 的标准化应条件下对前距腓韧带和跟腓韧带进行了超声检查。临床研究显示，FAI 组的前抽屉试验和距骨倾斜试验阳性率明显更高（分别为 p<0.001），右踝关节旋后明显增加（p=0.047），左踝关节跖屈明显增加（p=0.009）。与对照组相比，FAI 组的两条韧带的不均匀性和低回声性的超声观察率明显更高（分别为 p<0.05）。在 FAI 组中，前距腓韧带在应条件下明显更长，而在中立和应条件下，跟腓韧带均明显更长（分别为 p<0.05）。在 FAI 组中发现 22%的腓骨肌腱周围有腱周炎，而对照组为 6%。
