Ultrasound (US) changes within the Achilles tendon are present in asymptomatic Achilles individuals. We assessed the association of US signs with symptoms of Achilles tendinopathy in a study group of club level running athletes and in a control group of athletes training at least 2 times per week. The Achilles tendon was assessed in its entirety on longitudinal US scans, at the musculotendinous junction (MTJ), the calcaneal insertion site, and at a midtendon point. 25 middle distance runners, 19 males and 6 females, aged from 18 to 58, were enrolled in each group. When compared to control athletes, club level runners presented significantly increased tendon thickness (p=0.046) at the musculo-tendinous junction, and increased tendon thickness, with no statistical significance, at the other landmarks points. Although club level runners were significantly more symptomatic and predisposed to develop signs of tendinopathy than control athletes (p=<0.001), ultrasound abnormalities were not significantly associated with local symptoms complained at the US investigation time. Prospective studies on asymptomatic athletes are needed to define the predictive value of US signs of Achilles tendinopathy in the development of symptoms in the long-term.
在无症状的跟腱人群中，跟腱内存在超声（US）改变。我们在俱乐部级别的跑步运动员研究组和每周至少训练 2 次的运动员对照组中，评估了 US 征象与跟腱腱病症状的相关性。在整个跟腱的纵向 US 扫描中，在肌腱-肌交界处（MTJ）、跟骨插入部位和肌腱中部评估跟腱。每组纳入 25 名中长跑运动员，19 名男性和 6 名女性，年龄在 18 至 58 岁之间。与对照组运动员相比，俱乐部级别的跑步运动员在肌腱-肌交界处的肌腱厚度明显增加（p=0.046），在其他标志点的肌腱厚度也有增加，但无统计学意义。尽管俱乐部级别的跑步运动员比对照组运动员更有症状且更容易出现腱病的迹象（p=<0.001），但超声异常与 US 检查时报告的局部症状无显著相关性。需要对无症状运动员进行前瞻性研究，以确定跟腱腱病的 US 征象在长期发展为症状中的预测价值。
