PURPOSE To elucidate surgical outcomes in pediatric/adolescent patients with chronic lateral ankle instability and os subfibulare. METHODS A retrospective chart review was conducted of pediatric/adolescent patients with chronic lateral ankle instability and os subfibulare following simultaneous ossicle resection and lateral ligament repair using suture anchors with subsequent immediate full weightbearing and active range of motion exercises for the ankle in our department between 2013 and 2017. Clinical outcomes were evaluated by comparing preoperative and final follow-up American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS) and Karlsson-Peterson ankle function scores. Intervals between surgery and return to physical education in school were determined. RESULTS 31 feet of 15 male and 16 female patients were examined. Mean postoperative follow-up duration was 40.7 ± 12.7 (range 24-66) months. Mean AOFAS score increased significantly from 66.3 ± 2.5 (range 62-77) preoperatively to 96.5 ± 4.9 (range 87-100) at final follow-up (p < 0.001). Mean Karlsson-Peterson score increased significantly from 51.7 ± 4.0 (range 47-70) preoperatively to 95.3 ± 6.7 (range 80-100) at final follow-up (p < 0.001). Mean interval between surgery and return to physical education in school was 11.4 ± 1.6 (range 10-18) weeks. CONCLUSION Simultaneous ossicle resection and lateral ligament repair using suture anchors with subsequent immediate full weightbearing and active ankle range of motion exercises may give excellent clinical outcomes with early return to physical activity for chronic lateral ankle instability with os subfibulare in pediatric/adolescent patients desiring an early return to physical activity. Level of evidence III.

在患有慢性外侧踝关节不稳和os腓骨的小儿和青少年患者中，同时进行的听骨切除术和外侧韧带修复术可提供出色的临床效果，并尽早恢复体力活动。

目的阐明患有慢性外侧踝关节不稳和os亚腓骨的儿童/青少年患者的手术结局。方法回顾性分析2013年至2013年间在我科踝关节同时行小骨切除和外侧韧带修复的小儿/青少年患者，采用缝线锚钉同时行全骨负重和活动范围的踝关节活动和2017年。通过比较术前和最终随访的美国骨科足踝协会踝-脚足量表（AOFAS）和卡尔森-彼得森脚踝功能评分来评估临床结局。确定了从手术到重返学校的时间间隔。结果检查了15例男性和16例女性患者的31英尺。术后平均随访时间为40.7±12.7（范围24-66）个月。在最后一次随访时，平均AOFAS评分从术前的66.3±2.5（范围62-77）显着增加到96.5±4.9（范围87-100）（p <0.001）。最后一次随访时，平均Karlsson-Peterson评分从术前的51.7±4.0（范围47-70）显着提高到95.3±6.7（范围80-100）（p <0.001）。手术与重新上学之间的平均间隔为11.4±1.6（10-18周）。结论使用缝合锚钉同时进行骨小结切除和外侧韧带修复，随后立即进行完全负重和主动踝关节活动范围的运动，可为出色的临床结果，并为早年寻求早期治疗的小儿/青少年患者慢性侧踝不稳及os亚腓骨而恢复体力活动恢复体力活动。证据级别III。
