To compare the clinical outcomes of the modified Broström repair (MBR) with or without suture tape augmentation (STA) for managing the chronic lateral ankle instability.
72 patients with chronic lateral ankle instability treated at our hospital from January 2018 to July 2019 were included, with 37 patients receiving the MBR and 35 treated by the MBR with STA. The clinical efficacy of the two techniques was assessed in terms of VAS, AOFAS, and Karlsson scores and by physical examination in follow-ups.
In all 72 patients, operations were successful, and the patients were followed up for 29.3 months on average (range, 24-43 months). There were no significant differences in preoperative pain, AOFAS, and Karlsson scores between the two groups. Compared with preoperative findings, all the functional scores were significantly improved in both groups 3 months after the operation and at the last follow-up. Three months after the operation, the STA group had significantly lower VAS and higher AOFAS scores than the isolated MBR group, suggesting that patients in the STA group suffered less pain and achieved better functional improvement. However, the VAS and functional scores at the last follow-up and the Karlsson score at 3 months postoperatively showed no intragroup difference in both groups.
MBR with or without STA could achieve good results for the treatment of chronic lateral ankle instability. Compared with the widely used MBR, combining with STA may be more effective in promoting rehabilitation in early term.
比较改良 Broström 修复（MBR）联合或不联合缝线增强带（STA）治疗慢性外侧踝关节不稳定的临床效果。
纳入我院 2018 年 1 月至 2019 年 7 月收治的慢性外侧踝关节不稳定患者 72 例，其中 37 例行 MBR，35 例行 MBR 联合 STA。通过随访时的视觉模拟评分（VAS）、美国足踝外科协会（AOFAS）评分和 Karlsson 评分及体格检查评估两种技术的临床疗效。
72 例患者手术均顺利完成，平均随访 29.3 个月（24-43 个月）。两组患者术前疼痛、AOFAS 和 Karlsson 评分差异均无统计学意义。与术前相比，两组患者术后 3 个月及末次随访时所有功能评分均显著改善。术后 3 个月时，STA 组 VAS 评分低于 MBR 组，AOFAS 评分高于 MBR 组，提示 STA 组患者疼痛较轻，功能改善较好。但末次随访时 VAS 评分、功能评分及术后 3 个月时的 Karlsson 评分两组间差异均无统计学意义。
MBR 联合或不联合 STA 均可治疗慢性外侧踝关节不稳定，且疗效确切。与广泛应用的 MBR 相比，联合 STA 可能更有助于促进早期康复。
