目的:探讨全关节镜技术治疗急性闭合性非止点性跟腱断裂的临床效果。方法:回顾性分析2018年6月至2020年6月徐州市中心医院手足显微外科收治的采用全关节镜技术治疗的30例（30足）急性闭合性非止点性跟腱断裂患者的临床和影像学资料。男性26例，女性4例，年龄（38.3±8.5）岁（范围：19~66岁）。右侧22例，左侧8例，均为单侧断裂。受伤至手术时间（2.1±1.8）d（范围：1~7 d）。所有患者均采用全关节镜技术行镜下缝合治疗。术后采用疼痛视觉模拟评分（VAS）、美国足踝外科协会（AOFAS）踝与后足评分、跟腱断裂评分（ATRS）评估踝部功能恢复情况，采用Arner-Lindholm评分评价临床疗效。结果:患者术后随访（18.6±2.2）个月（范围：12~28个月），所有患者切口均一期愈合，无切口感染、皮肤坏死、跟腱再次断裂等并发症发生。2例患者诉长时间运动后跟部紧张不适感，经拉伸和理疗后完全缓解，1例患者诉单足提踵无力，经反复提踵功能练习后恢复。末次随访时，患者的VAS［n M（IQR）］由术前的6（5）分降至0（1）分（n Z=6.512，n P<0.01）；AOFAS踝-后足评分由术前的（60.6±8.3）分升至（96.3±4.8）分（n t=-29.774，n P<0.01）；ATRS由术前的（61.6±7.8）分升至（97.1±2.3）分（n t=-53.661，n P<0.01），差异均有统计学意义。Arner-Lindholm评分：优27例，良3例，优良率为100%（30/30）。n 结论:采用全关节镜技术治疗急性闭合性非止点性跟腱断裂，既保证了跟腱断端缝合的质量，又可避免腓肠神经的损伤，具有创伤小、恢复快、并发症少等优点。“,”Objective:To investigate the clinical effiacy of arthroscopic treatment of acute closed noninsertional rupture of Achilles tendon.Methods:The clinical and imaging data of 30 patients (30 feet) with acute closed noninsertional rupture of Achilles tendon who were treated with all-inside arthroscopic technique at the Department of Hand and Foot Microsurgery,Xuzhou Central Hospital from June 2018 to June 2020 were analyzed retrospectively. There were 26 males and 4 females,aged (38.3±8.5)years old(range:19 to 66 years),and the right sides was involved in 22 cases and left sides in 8 cases.The duration from injury to surgery was (2.1±1.8) days (range:1 to 7 days).All patients were treated with all-inside arthroscopic technique.The function of the ankle and the foot was assessed using visual analogue scale (VAS),the American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale and the Achilles tendon total rupture score (ATRS),and the Arner-Lindholm score system were used to evaluate the excellent and good rate.Results:The patients were followed up for (18.6±2.2)months(range:12 to 28 months).All the wounds healed at the first stage.No complications such as infection,sural nerve injury or re-rupture happened.Two patinets felt mild pain after a long time exercise, and were alleviated by microwave therapy,and stretching the achilles tendon consistently.Another patient was unable to do a sustained single stance heel raise,which was recovered after repeated function practice.At the last follow-up,the VAS(n M(IQR))decreased from 6(5) preoperative to 0(1)(n Z=6.512,n P<0.01),the AOFAS ankle hindfoot scale improved from 60.6±8.3 preoperative to 96.3±4.8(n t=-29.774,n P<0.01),and the ATRS improved from 61.7±7.8 preoperative to 97.1±2.3 (n t=-53.661,n P<0.01).According to the Arner-Lindholm score system,27 cases were excellent,3 cases were good,and the excellent and good rate was 100%.n Conclusions:The all-inside arthroscopic technique not only ensures the quality of tendon ananstomosis,but also avoids injury to the sural nerve.It has the advantages of small trauma,faster recovery and fewer complications.
