: Although lateral ligament augmentation using suture-tape has been effective for restoration of mechanical ankle stability, few data are available regarding changes of peroneal strength, proprioception, and postural control. The aim of this study was to determine effects of suture-tape augmentation on functional ankle instability (FAI).
: Twenty-four patients who underwent suture-tape augmentation were eligible and were followed more than 2 years postoperatively. Functional outcomes were evaluated with the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM). Changes of peroneal strength, proprioception and postural control were analyzed with an isokinetic dynamometer and a modified Romberg test.
: CAIT and FAAM (average of daily and sports activity scores) significantly improved to average 27.2 points and 86.7 points, respectively, at final follow-up. Peak torque for eversion in 60 degrees/s angular velocity significantly improved to 10.6 Nm at final follow-up. Deficit ratio of peak torque for eversion significantly improved from mean 39.5% to 20.9%, and significant side-to-side difference was revealed ( P < .001). There were no significant differences in joint position sense. A significant improvement in balance retention time was revealed at final follow-up, and the relative deficit ratio compared to the unaffected side was 30.9%.
: Patient-reported functional outcomes significantly improved after lateral ligament augmentation using suture-tape. Although this procedure demonstrated significant effects on FAI based on improvement of isokinetic peroneal strength and postural control, recovery rates compared to the unaffected side were not significant at the intermediate-term follow-up. In addition, there was no positive effect on proprioception of the ankle.

尽管使用缝线带进行侧副韧带增强已被证明可有效恢复踝关节机械稳定性，但关于腓骨力量、本体感觉和姿势控制变化的数据却很少。本研究旨在确定缝线带增强对功能性踝关节不稳定（FAI）的影响。
24 名接受缝线带增强的患者符合条件，并在术后 2 年以上进行随访。采用 Cumberland 踝关节不稳定工具（CAIT）和足部和踝关节能力测量（FAAM）评估功能结果。使用等速测力计和改良 Romberg 测试分析腓骨力量、本体感觉和姿势控制的变化。
CAIT 和 FAAM（日常和运动活动评分的平均值）在最终随访时分别显著改善至平均 27.2 分和 86.7 分。60 度/秒角速度的外翻峰值扭矩最终随访时显著改善至 10.6 Nm。外翻峰值扭矩的缺陷比从平均 39.5%显著改善至 20.9%，并且显示出显著的侧间差异（P<0.001）。关节位置感没有显著差异。最终随访时平衡保留时间显著改善，与未受影响侧相比，相对缺陷比为 30.9%。
使用缝线带进行侧副韧带增强后，患者报告的功能结果显著改善。尽管该手术基于改善等速腓骨力量和姿势控制对 FAI 显示出显著效果，但在中期随访时与未受影响侧相比，恢复率并不显著。此外，对踝关节本体感觉没有积极影响。
