Abstract：
Objective: To examine the feasibility and clinical effect of all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening for Achilles tendon contracture. Methods: This is a retrospective case series study. From February 2021 to February 2023, the clinical data of 24 patients (30 feet) with Achilles tendon contracture treated with all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening were analyzed retrospectively. There were 10 males and 14 females, aged (32.8±16.1) years (range: 9 to 62 years). There were 8 cases of left side only, 10 cases of right side only and 6 cases of bilateral. There were 14 cases (16 feet) of foot varus, 4 cases (6 feet) of foot valgus, and 6 cases (8 feet) without deformity. All patients underwent all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening. The surgical effects were evaluated using the maximum dorsal extension angle of ankle joint in knee extension position, the visual analogue scale (VAS) of pain, the American Orthopedic Foot and Ankle Society ankle-hindfoot score(AOFAS-AH). Paired sample t test was used to compare the scores before and after operation. Results: All patients successfully completed the operation, and the operation time of Achilles tendon lengthening was (22.0±5.7)minutes (range: 15 to 35 minutes) and the intraoperative blood loss was (6.5±2.7)ml (range: 2 to 15 ml). All patients primarily healing without any complications such as sural nerve injury, Achilles tendon rupture, important blood vessel injury, and obvious decrease of lift heel strength of achilles tendon. All 24 patients were followed up for (17.2±4.5) months (range: 12 to 28 months). One patient suffered from lift heel\'s weakness in one foot after operation, and recovered after repeated lift heel functional exercises. The ankle dorsiflexion function of two patients with calf triceps spasm were not improved after operation, and it was obviously improved after botulinum toxin injection. At the last follow-up, the maximum dorsal extension angle of ankle joint in knee extension position increased from -9.2°±7.6°(range:-25° to 5°) preoperatively to 14.5°±7.0°(range:0° to 28°)(t=24.83, P<0.01); the VAS score was reduced from (4.5±1.7) points (range:1 to 8 points) preoperatively to (1.5±0.9) points (range:0 to 3 points) (t=9.53, P<0.01), the AOFAS-AH was increased from (60.5±11.4)points (range:38 to 85 points) to (90.8±5.4) points (range:80-100 points)(t=14.21, P<0.01). Conclusions: All-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening for Achilles tendon contracture not only provides Achilles tendon lengthening, but also avoids complications such as Achilles tendon rupture and sural nerve injury. It is an effective method for the treatment of Achilles tendon contracture.
目的： 探讨远近端双通道全关节镜下双向半切跟腱延长技术治疗跟腱挛缩的可行性及临床效果。 方法： 本研究为回顾性病例系列研究。回顾性分析2021年2月到2023年2月徐州市中心医院手足显微外科收治的采用远近端双通道全关节镜下双向半切跟腱延长技术治疗的24例（30足）跟腱挛缩患者的临床资料。男性10例，女性14例，年龄（32.8±16.1）岁（范围：9~62岁）。单纯左侧8例，单纯右侧10例，双侧6例；足内翻14例（16足），足外翻4例（6足），无内外翻畸形6例（8足）。所有患者均采用远近端双通道全关节镜技术行跟腱延长，术后采用膝关节伸直位踝关节最大背伸角度、疼痛视觉模拟评分（VAS）、美国足踝外科协会踝-后足评分（AOFAS-AH）对手术治疗效果进行评价。手术前后评分的比较采用配对样本t检验。 结果： 所有患者均顺利完成手术，跟腱延长手术时间（22.0±5.7）min（范围：15~35 min）；术中出血量（6.5±2.7）ml（范围：2~15 ml）。所有患者切口均获得一期愈合，未出现腓肠神经损伤、跟腱断裂、重要血管损伤、跟腱提踵力量明显下降等并发症。24例患者均获得随访，随访时间（17.2±4.5）个月（范围：12~28个月）。1例患者术后单足提踵无力，经反复提踵功能练习后恢复。2例合并小腿三头肌痉挛患者术后踝关节背伸功能改善欠佳，行肉毒素注射后得到明显改善。末次随访时患者膝关节伸直位踝关节最大背伸角度由术前的-9.2°±7.6°（范围：-25°~5°）提高至14.5°±7.0°（范围：0°~28°）（t=24.83，P<0.01），VAS由术前的（4.5±1.7）分（范围：1~8分）降至术后的（1.5±0.9）分（范围：0~3分）（t=9.53，P<0.01）；AOFAS-AH由术前的（60.5±11.4）分（范围：38~85分）提高至术后的（90.8±5.4）分（范围：80~100分）（t=14.21，P<0.01）。 结论： 采用远近端双通道全关节镜下双向半切跟腱延长技术治疗跟腱挛缩，既实现了跟腱的最大程度延长，又避免了跟腱断裂、腓肠神经损伤等并发症的发生，具有创伤小、恢复快、治疗精准、并发症少等优点，是治疗跟腱挛缩的可选方法。.
