[Arthroscopic treatment of acute closed noninsertional rupture of Achilles tendon].

Objective: To investigate the clinical efficacy 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). There were 22 cases on the right side and 8 cases on the left side. The duration from injury to surgery was (2.1±1.4) 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). The Arner-Lindholm score system was used to evaluate the excellent and good rate of clinical effect. Paired sample t test or rank-sum test was used for data comparison. 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 complication 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 (M(IQR)) decreased from 6(5) preoperatively to 0(1)(Z=6.512,P<0.01),the AOFAS ankle hindfoot scale improved from 60.6±8.3 preoperatively to 96.3±4.8(t=-29.774,P<0.01),and the ATRS improved from 61.7±7.8 preoperatively to 97.1±2.3 (t=-53.661,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%. 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.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±1.4）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。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。数据比较采用配对样本t检验或秩和检验。 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［M（IQR）］由术前的6（5）分降至0（1）分（Z=6.512，P<0.01）；AOFAS踝与后足评分由术前的（60.6±8.3）分升至（96.3±4.8）分（t=-29.774，P<0.01）；ATRS由术前的（61.7±7.8）分升至（97.1±2.3）分（t=-53.661，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）。 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。.
