: As a representative anatomic ankle ligament repair technique, the Broström procedure continues to be modified to reach better clinical outcomes, superior mechanical stability, early rehabilitation, and minimal risk of recurrent instability. This study aimed to evaluate the intermediate-term clinical outcomes after the modified Broström procedure (MBP) with suture-tape augmentation for chronic lateral ankle instability. : Ninety-four patients with chronic lateral ankle instability were followed for ≥3 years after MBP augmented with suture tape. The patient-reported clinical outcomes were evaluated with the Foot and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measure (FAAM). The changes in mechanical ankle stability were evaluated with physical examination and periodic stress radiography. The changes in static and dynamic postural control ability were assessed with the single-leg stance test and Biodex posturography. : FAOS and FAAM scores significantly improved from preoperative means of 52.6 and 54.2 points to 91.8 and 90.5 points at final follow-up, respectively ( < 0.001). Talar tilt angle and anterior talar translation significantly improved from preoperative means of 15.4° and 14.3 mm to 2.7° and 4.5 mm at final follow-up, respectively ( < 0.001). Two patients (2.1%) complained of a recurrence of mechanical and functional instability. One patient (1.1%) showed non-specific inflammation related to a suture tape. Balance retention time significantly improved from a preoperative mean of 3.7 to 6.4 s at final follow-up ( < 0.001), with a non-significant side-to-side difference. The overall stability index significantly improved from a preoperative mean of 3.7 to 1.9 at final follow-up ( < 0.001), with a significant side-to-side difference. : The MBP augmented with suture tape appears to be an effective surgical technique for chronic lateral ankle instability. Through anatomic repair of attenuated ankle ligaments and suture-tape augmentation, this modified procedure can provide reliable stability and minimal risk of recurrent instability. In addition, static and dynamic postural control ability may be improved through continuous proprioceptive-oriented rehabilitation following surgery.
作为一种具有代表性的踝关节韧带解剖修复技术，布罗斯特伦手术（Broström procedure）不断改进以获得更好的临床效果、更高的机械稳定性、更早的康复以及更低的复发性不稳定风险。本研究旨在评估采用缝线带增强的改良布罗斯特伦手术（MBP）治疗慢性外侧踝关节不稳定的中期临床效果。：94例慢性外侧踝关节不稳定患者在接受缝线带增强的MBP手术后随访≥3年。采用足踝结局评分（FAOS）和足踝能力测量（FAAM）评估患者报告的临床效果。通过体格检查和定期应力X线摄影评估踝关节机械稳定性的变化。采用单腿站立试验和Biodex姿势描记法评估静态和动态姿势控制能力的变化。：FAOS和FAAM评分从术前的平均52.6分和54.2分分别显著提高到末次随访时的91.8分和90.5分（<0.001）。距骨倾斜角和距骨前移分别从术前的平均15.4°和14.3 mm显著改善到末次随访时的2.7°和4.5 mm（<0.001）。2例患者（2.1%）主诉机械性和功能性不稳定复发。1例患者（1.1%）出现与缝线带相关的非特异性炎症。平衡保持时间从术前的平均3.7秒显著提高到末次随访时的6.4秒（<0.001），左右侧差异无统计学意义。总体稳定性指数从术前的平均3.7显著提高到末次随访时的1.9（<0.001），左右侧差异有统计学意义。：采用缝线带增强的MBP似乎是治疗慢性外侧踝关节不稳定的一种有效手术技术。通过对减弱的踝关节韧带进行解剖修复和缝线带增强，这种改良手术可以提供可靠的稳定性和最低的复发性不稳定风险。此外，术后持续进行以本体感觉为导向的康复训练可能会改善静态和动态姿势控制能力。
