Studies have shown that elongation of the injured Achilles tendon after acute Achilles tendon rupture (ATR) is negatively associated with clinical outcomes. The difference between operative and non-operative treatment on the length of the Achilles tendon is only sparsely investigated. The aim of the study was to investigate if the operative and non-operative treatment of ATR had different effects on tendon elongation.
The study was performed as a registry study in the Danish Achilles tendon database (DADB). The primary outcome of the study was an indirect measure of Achilles tendon length: the Achilles tendon resting angle (ATRA) at 1-year follow-up. The variable of interest was treatment (operative or non-operative).
From August 2015 to January 2019, 438 patients (154 operatively treated and 284 non-operatively treated) were registered with full baseline data and had their ATRA correctly registered at 1-year follow-up in DADB. The analysis did not show a clinically relevant nor statistically significant difference in ATRA between operative and non-operatively treated patients at 1-year follow-up (mean difference - 1.2°; 95% CI - 2.5; 0.1; n.s) after adjustment for potential confounders.
There were neither clinically relevant nor statistically significant differences in terms of the ATRA at 1-year follow-up between the operative and non-operatively treated patients. This finding suggests that operative treatment does not lead to a clinically relevant reduction in tendon elongation compared to non-operative treatment and it should therefore not be used as an argument in the choice of treatment.

研究表明，急性跟腱断裂（ATR）后跟腱的延长与临床结果呈负相关。手术与非手术治疗对跟腱长度的影响差异仅得到了稀疏的研究。本研究旨在探讨 ATR 的手术与非手术治疗是否对跟腱延长有不同的影响。
本研究在丹麦跟腱数据库（DADB）中进行了一项注册研究。本研究的主要结果是跟腱长度的间接测量：1 年随访时的跟腱休息角（ATRA）。感兴趣的变量是治疗（手术或非手术）。
2015 年 8 月至 2019 年 1 月，438 名患者（154 例手术治疗和 284 例非手术治疗）在 DADB 中注册了完整的基线数据，并在 1 年随访时正确记录了他们的 ATRA。分析显示，在调整了潜在混杂因素后，手术与非手术治疗患者在 1 年随访时的 ATRA 之间没有临床相关且无统计学意义的差异（平均差异-1.2°；95%CI-2.5；0.1；n.s）。
在 1 年随访时，手术与非手术治疗患者的 ATRA 之间既没有临床相关的差异，也没有统计学意义的差异。这一发现表明，与非手术治疗相比，手术治疗并不能显著减少跟腱延长，因此不应将其作为治疗选择的理由。
