(1) Background: It is unknown which imaging parameters are associated with clinical persistent symptoms in postoperative Achilles tendons. This study used B-Mode, Power Doppler (PD-US), Ultrasound Tissue Characterization (UTC) and Shear Wave Elastography (SWE) to investigate which imaging parameters are associated with persistent symptoms in postoperative Achilles tendon tissue. (2) Methods: Retrospective, cross-sectional, multimodal imaging study. Based on the VISA-A score, postoperative tendons were assigned to two groups: 1. asymptomatic (VISA-A ≥ 90, = 18); 2. symptomatic (VISA-A < 90, = 10). The following imaging parameters were analyzed: UTC (echo type I, II, III, IV), B-Mode (diameter, cross sectional area, calcification, fiber irregularity), PD-US (Öhberg score) and SWE (SWE 3 mm, SWE area) using a -test and a test. (3) Results: SWE and PD-US showed significantly reduced elasticity and increased neovascularization in symptomatic tendons (SWE 3 mm = 0.031, SWE area = 0.046, Öhberg score < 0.001). The only significant correlation between imaging parameters and the VISA-A score was assessed for SWE 3 mm (r = 0.378; = 0.047) and the Öhberg score (r = -0.737; < 0.001). Conclusions: Symptomatic postoperative Achilles tendons showed increased neovascularization and lower SWE values than asymptomatic ones. Future studies should examine the diagnostic accuracy of PD-US and SWE in detecting current symptoms in postoperative Achilles tendons.
（1）背景：目前尚不清楚哪些成像参数与术后跟腱的临床持续症状相关。本研究使用B超、功率多普勒超声（PD-US）、超声组织特性分析（UTC）和剪切波弹性成像（SWE）来研究哪些成像参数与术后跟腱组织的持续症状相关。（2）方法：回顾性、横断面、多模态成像研究。根据VISA-A评分，将术后肌腱分为两组：1.无症状组（VISA-A≥90，n = 18）；2.有症状组（VISA-A＜90，n = 10）。使用t检验和F检验分析以下成像参数：UTC（回声类型I、II、III、IV）、B超（直径、横截面积、钙化、纤维不规则性）、PD-US（奥伯格评分）和SWE（SWE 3mm、SWE面积）。（3）结果：有症状的肌腱中，SWE和PD-US显示弹性显著降低，新生血管形成增加（SWE 3mm P = 0.031，SWE面积P = 0.046，奥伯格评分P＜0.001）。成像参数与VISA-A评分之间唯一显著的相关性是SWE 3mm（r = 0.378；P = 0.047）和奥伯格评分（r = -0.737；P＜0.001）。结论：有症状的术后跟腱比无症状的跟腱新生血管形成增加，SWE值更低。未来的研究应检验PD-US和SWE在检测术后跟腱当前症状方面的诊断准确性。
