目的:探讨全后足关节镜下肌腹部分切除术治疗n 长屈肌腱撞击综合征的手术方法和临床效果。n 方法:回顾性分析徐州市中心医院2016年1月—2018年10月接受全后足关节镜下的n 长屈肌腱部分肌腹切除联合部分腱鞘清理治疗的27例(27足)n 长屈肌腱撞击综合征患者的临床资料，其中男17例(17足)、女10例(10足)，年龄19～45(28.78±7.85)岁，右侧15例、左侧12例，病程6～41(18.33±7.74)个月。术后随访，观察并发症情况及足踝部运动情况，末次随访采用疼痛视觉模拟量表(VAS)、美国足踝外科协会(AOFAS)踝与后足评分、Karlsson踝关节功能评分(KAFS)进行疗效评价。n 结果:患者术后切口均获一期愈合，未出现神经、血管及肌腱损伤等并发症。患者均获随访8～41(25.37±9.07)个月。末次随访时，踝关节后侧疼痛完全消失，踝关节及n 趾活动正常，疼痛VAS评分0分，AOFAS评分(98.15±2.38)分(优26例、良1例)，KAFS评分(98.41±1.45)分，与术前比较，差异均有统计学意义(n P值均<0.05)。n 结论:全后足关节镜下肌腹部分切除术治疗n 长屈肌腱撞击综合征，手术创伤小，功能恢复快，效果可靠，建议临床推广应用。n “,”Objective:This study aims to investigate the surgical technique and the clinical results of the all-inside hindfoot arthroscopic treatment of the flexor hallucis longus tendon impingement syndrome.Methods:The data of the 27 patients with flexor hallucis longus tendon impingement syndrome (27 feet, 17 males [17 feet] and 10 females [10 feet]; aged 19-45[28.78 ± 7.85] years) treated with the all-inside arthroscopy and had complete follow-up data in Xuzhou Central Hospital from January 2016 to October 2018 were retrospectively analyzed. The right and the left sides were involved in 15 and 12 cases (feet), respectively. The mean disease duration from the specialist doctor intervention to operation was (18.33±7.74) months (range: 6-41 months). The preoperation visual analog pain scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale and Karlsson Ankle Functional Score (KAFS) were used to evaluate the function.Results:All cases achieved healing of the wound without postoperative nerve, vessel, and tendon complications. All patients were followed up for 8-41 months (25.37±9.07) months. At the final follow-up, complete pain relief and normal hallucis and ankle activity were recorded. The mean VAS, AOFAS, and KAFS were 0, 98.15±2.38, and 98.41±1.45, respectively. According to the AOFAS, 26 patients achieved excellent rating, and 1 patient achieved good rating. All above functional scores postoperation were significantly improved compared with those preoperation (all n P values<0.05).n Conclusions:The all-inside hindfoot arthroscopic treatment of the flexor hallucis longus tendon impingement syndrome is an effective, minimally invasive, and precise treatment procedure and provides satisfactory results.
