Abstract

Background: Minimally invasive techniques have emerged as promising options for the surgical treatment of acute Achilles tendon ruptures, aiming to reduce complication rates associated with open procedures. However, comparative data between different minimally invasive methods are limited.

Methods: In this retrospective case series, we evaluated 102 patients treated with either the Dresden or PARS/Knotless technique between January 2017 and June 2021. Clinical outcomes included time to return to sports, ankle range of motion, Achilles Tendon Total Rupture Score (ATRS), and postoperative complications. Postoperative complications were also documented.

Results: Both groups demonstrated similar rates of return to sports (91.48% PARS/Knotless vs 92.70% Dresden) and comparable ATRS scores (91.1 ± 6.7 vs 92.3 ± 8.9, P = .47). Surgical time was significantly shorter with the Dresden technique (38.3 ± 8.5 vs 43.5 ± 8.9 minutes, P = .005). The overall complication rate was significantly lower in the Dresden group (10.90% vs 29.78%, P = .024), primarily because of lower rates of calcaneodynia.

Conclusion: Although both techniques demonstrated similar functional outcomes, the Dresden procedure was associated with a lower complication rate.

微创跟腱修复：Dresden与PARS/无结技术的回顾性比较研究。

背景：微创技术已成为急性跟腱断裂手术治疗的有希望的选择，旨在减少与开放手术相关的并发症发生率。然而，不同微创方法之间的比较数据有限。方法：在这个回顾性病例系列中，我们评估了2017年1月至2021年6月期间接受Dresden或PARS/Knotless技术治疗的102例患者。临床结果包括恢复运动时间、踝关节活动范围、跟腱总断裂评分（ATRS）和术后并发症。术后并发症也有记录。结果：两组的运动恢复率相似（91.48% PARS/Knotless vs 92.70% Dresden）， ATRS评分相似（91.1±6.7 vs 92.3±8.9,P = 0.47）。Dresden技术的手术时间明显缩短（38.3±8.5 vs 43.5±8.9 min, P = 0.005）。德累斯顿组的总并发症发生率明显较低（10.90% vs 29.78%, P = 0.024），主要原因是跟痛症发生率较低。结论：虽然两种技术表现出相似的功能结果，但德累斯顿手术的并发症发生率较低。
