Arthroscopic lateral ankle ligament repair for chronic lateral ankle instability (CLAI) yields good clinical results. However, the healing process of the ligament after anatomical repair remains unclear. This study evaluated the functional and patient-based outcomes for CLAI patients who underwent arthroscopic lateral ankle ligament repair and the morphological condition of the repaired anterior talofibular ligament (ATFL).
We retrospectively reviewed 47 patients (50 ankles) who underwent arthroscopic lateral ankle ligament repair for CLAI (mean follow-up, 14 months). The Japanese Society for Surgery of the Foot Ankle-Hindfoot (JSSF) scale score and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were assessed preoperatively and 12 months postoperatively. Magnetic resonance imaging (MRI) was performed preoperatively and at 6 and 12 months postoperatively to evaluate the ATFL. The functional and patient-based outcomes were compared between the group with repaired ATFLs and high signal intensity and the group with repaired ATFLs and low signal intensity.
The mean JSSF score improved significantly from 72.3 ± 11.6 preoperation to 95.3 ± 5.4 at 12 months postoperation. The MRI findings at 12 months postoperation showed that each repaired ATFL had a linear band structure from the talar to the fibular attachment site, and 41 of 50 ankles (82%) had low signal intensity of the ligament. On the SAFE-Q, the social functioning scores at 12 months postoperation were significantly higher in the low signal intensity group than in the high signal intensity group.
Arthroscopic lateral ankle ligament repair for CLAI yielded good functional and patient-based outcomes and restored the morphological condition of the ATFL.

关节镜下外侧踝关节韧带修复术治疗慢性外侧踝关节不稳定（CLAI）可获得良好的临床效果。然而，韧带在解剖修复后的愈合过程仍不清楚。本研究评估了接受关节镜下外侧踝关节韧带修复术治疗 CLAI 的患者的功能和基于患者的结果，以及修复的前距腓韧带（ATFL）的形态状况。
我们回顾性分析了 47 例（50 足）接受关节镜下外侧踝关节韧带修复术治疗 CLAI 的患者（平均随访 14 个月）。术前和术后 12 个月评估日本足踝外科协会（JSSF）评分和自我足部评估问卷（SAFE-Q）。术前和术后 6 个月和 12 个月行 MRI 检查评估 ATFL。比较修复的 ATFL 高信号强度组和低信号强度组与修复的 ATFL 低信号强度组的功能和基于患者的结果。
JSSF 评分从术前的 72.3±11.6 显著改善至术后 12 个月的 95.3±5.4。术后 12 个月的 MRI 结果显示，每个修复的 ATFL 均具有从距骨到腓骨附着点的线性带结构，50 足中有 41 足（82%）的韧带呈低信号强度。在 SAFE-Q 上，术后 12 个月时，低信号强度组的社会功能评分明显高于高信号强度组。
关节镜下外侧踝关节韧带修复术治疗 CLAI 可获得良好的功能和基于患者的结果，并恢复 ATFL 的形态状况。
