Abstract:
Objective: To evaluate the clinical outcome of the reconstruction of Myerson type Ⅲ chronic Achilles tendon rupture by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft. Methods: Clinical data of 32 patients(32 ankles) with Myerson type Ⅲ chronic Achilles tendon rupture who were treated by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft at Department of Hand and Foot Microsurgery, Xuzhou Central Hospital from September 2013 to September 2018 were analyzed retrospectively.There were 28 males and 4 females, aged 45.5 years old(range: 22 to 69 years old), 12 cases in the right side and 20 in the left.All patients were treated by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft for Myerson type Ⅲ chronic Achilles tendon rupture reconstruction.The functional recovery of the ankle was evaluated according to ankle-hindfood score of American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale, Achilles tendon total rupture score (ATRS), visual analogue scale (VAS).Arner-Lindholm score was used to evaluate the excellent and good rate.The quantitative data were compared using t-test or Wilcoxon test. Results: The 32 patients were followed up for 33 months (range: 15 to 72 months).No serious postoperative complications such as infection, sural nerve injury or tend re-rupture outcomes were reported.Three patients complained of mild pain when after a minimum sitting, walking or jogging, which were completely relieved by simple physical therapy or continuous stretching of Achilles tendon.At the last follow-up, the VAS decreased from 3 (5) (M (Q(R)) ) preoperative to 0 (3) (Z=1.357, P<0.01) and AOFAS ankle hindfoot scale improved from 58.6±13.5 preoperative to 95.5±4.0 (t=16.9, P=0.00), ATRS improved from 47.5±9.3 preoperative to 96.6±3.3 (t=25.661, P<0.01).According to the score of Arner-Lindholm, 20 cases were excellent, 12 cases were good, and the excellent and good rate was 100%. Conclusion: The reconstruction of Myerson type Ⅲ chronic Achilles tendon rupture by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft has the advantages of safety, reliability, effectiveness and minor injury. 目的： 探讨全关节镜下自体半腱肌及股薄肌肌腱修复Myerson Ⅲ型陈旧性跟腱断裂的疗效。 方法： 回顾性分析2013年9月至2018年9月徐州市中心医院手足显微外科采用全关节镜下自体半腱肌及股薄肌肌腱修复的32例（32足）MyersonⅢ型陈旧性跟腱断裂患者的临床资料。其中男性28例，女性4例，平均年龄45.5岁（范围：22~69岁），左侧20例，右侧12例，平均受伤至手术时间为10周（范围：5~24周）。所有患者均采用全关节镜下自体半腱肌及股薄肌肌腱修复Myerson Ⅲ型陈旧性跟腱断裂的手术治疗，术后采用疼痛视觉模拟评分（VAS)、美国足踝外科协会（AOFAS）踝-后足评分、跟腱断裂评分（ATRS）评价足踝部功能恢复情况，使用Arner-Lindholm评分评定优良率。手术前后指标比较采用独立样本t检验或非参数Wilcoxon检验。 结果： 所有患者均获得随访，随访时间33个月（范围：15~72个月）。所有患者均无伤口感染、腓肠神经损伤、跟腱再次断裂等并发症发生。3例患者长时间坐、走或慢跑后有轻微跟部疼痛，经过简单理疗或者持续拉伸跟腱得到完全缓解。末次随访时，患者的VAS由术前的3（5）分[M（Q(R)）]降至0（3）分（Z=1.357，P<0.01），AOFAS踝-后足评分由术前的（58.6±13.5）分升至（95.5±4.0）分（t=27.933，P<0.01），ATRS由术前的（47.5±9.3）分升至（96.6±3.3）分（t=25.661，P<0.01），差异均有统计学意义。Arner-Lindholm评分优20例，良12例，优良率为100%。 结论： 全关节镜下自体半腱肌及股薄肌肌腱修复MyersonⅢ型陈旧性跟腱断裂，安全可靠、疗效确切。.
