Abstract：
BACKGROUND With the development of arthroscopy and suture anchor, the modified Brostrӧm technique has made remarkable progress. However, it is unclear which material is most suitable for treating anterior talofibular ligament injury (ATFL). This study evaluated the short-term efficacy of 2 suture anchors (metal vs biodegradable materials) in arthroscopic ATFL repair. MATERIAL AND METHODS From January 2018 to December 2019, 82 patients with ankle disorders (51 men and 31 women) with ATFL injury received arthroscopic repair with suture anchor through the Brostrӧm-Gould procedure. The mean age was 38.70±9.35 years (range, 18-54 years). Each patient was followed up. American Orthopedic Foot and Ankle Society score (AOFAS), Karlsson Ankle Functional Score (KAFS), and the Visual Analogue Scale (VAS) were used to evaluate functional status and pain. RESULTS All patients were followed up for 21.21±2.19 months (range, 18-25 months). No complications were found either group. Preoperative clinical and functional scores in both groups had no significant difference (P>0.05). The functional score increased significantly in both groups (P<0.001). At the last follow-up, the mean AOFAS score was 93.00 (90.00, 96.00) in the Biodegradable group and 93.50 (91.00, 96.00) in the Metallic group (P=0.31). The mean KAFS score was 91.50 (85.00, 95.00) in the Biodegradable group and 93.00 (90.00, 95.50) in the Metallic group (P=0.10); the mean VAS score was 1.50 (1.00, 1.80) in the Biodegradable group and 1.30 (0.98, 1.70) in the Metallic group (P=0.22). CONCLUSIONS Arthroscopic repair of ATFL injury with suture anchors can improve the prognosis of CAI. There were no statistically significant differences in clinical and functional outcomes with metal or biodegradable suture anchors at short-term follow-up.
摘要：
背景随着关节镜技术和缝合锚钉技术的发展,改良的Brostratm技术取得了显著进展。然而,尚不清楚哪种材料最适合治疗前腓骨韧带损伤（ATFL）。本研究评估了2种缝合锚钉（金属与生物可降解材料）在关节镜ATFL修复中的短期疗效。材料与方法2018年1月至2019年12月，82例踝关节疾病伴ATFL损伤患者（男51例，女31例）通过Brostringm-Gould手术进行关节镜下缝合锚修复。平均年龄为38.70±9.35岁(范围，18-54岁）。对每位患者进行随访。美国骨科足踝协会评分（AOFAS），卡尔松踝关节功能评分（KAFS），视觉模拟评分(VAS)用于评估功能状态和疼痛。结果所有患者随访时间为21.21±2.19个月(范围,18-25个月）。两组均未发现并发症。两组患者术前临床及功能评分差异无统计学意义(P>0.05)。两组的功能评分均显著升高(P<0.001)。在最后一次随访中，可生物降解组的平均AOFAS评分为93.00(90.00,96.00),金属组的平均AOFAS评分为93.50(91.00,96.00)(P=0.31).可生物降解组的平均KAFS评分为91.50（85.00，95.00），金属组的平均KAFS评分为93.00（90.00，95.50）（P=0.10）；可生物降解组的平均VAS评分为1.50（1.00，1.80），金属组的平均VAS评分为1.30（0.98，1.70）（P=0.22）。结论关节镜下缝合锚钉修复ATFL损伤可改善CAI预后。在短期随访中，使用金属或可生物降解的缝合锚钉的临床和功能结果没有统计学上的显着差异。
