The study investigated the incidence of Achilles and patellar tendinopathy in adolescent elite athletes and non-athletic controls. Furthermore, predictive and associated factors for tendinopathy development were analyzed. The prospective study consisted of two measurement days (M1/M2) with an interval of 3.2±0.9 years. 157 athletes (12.1±0.7 years) and 25 controls (13.3±0.6 years) without Achilles/patellar tendinopathy were included at M1. Clinical and ultrasound examinations of both Achilles (AT) and patellar tendons (PT) were performed. Main outcome measures were incidence tendinopathy and structural intratendinous alterations (hypo-/hyperechogenicity, vascularization) at M2 [%]. Incidence of Achilles tendinopathy was 1% in athletes and 0% in controls. Patellar tendinopathy was more frequent in athletes (13%) than in controls (4%). Incidence of intratendinous alterations in ATs was 1-2% in athletes and 0% in controls, whereas in PTs it was 4-6% in both groups (p>0.05). Intratendinous alterations at M2 were associated with patellar tendinopathy in athletes (p≤0.01). Intratendinous alterations at M1, anthropometric data, training amount, sports or sex did not predict tendinopathy development (p>0.05). Incidence of tendinopathy and intratendinous alterations in adolescent athletes is low in ATs and more common in PTs. Development of intratendinous alterations in PT is associated with tendinopathy. However, predictive factors could not be identified.
该研究调查了青少年精英运动员和非运动员对照组中跟腱和髌腱病的发病率。此外，还分析了腱病发展的预测因素和相关因素。这项前瞻性研究包括两个测量日（M1/M2），间隔为3.2±0.9年。在M1时纳入了157名运动员（12.1±0.7岁）和25名对照组（13.3±0.6岁），他们均无跟腱/髌腱病。对跟腱（AT）和髌腱（PT）进行了临床和超声检查。主要观察指标是M2时腱病的发病率和肌腱内结构改变（低回声/高回声、血管形成）[百分比]。运动员中跟腱病的发病率为1%，对照组为0%。髌腱病在运动员中（13%）比对照组（4%）更常见。运动员跟腱的肌腱内改变发生率为1-2%，对照组为0%，而两组髌腱的发生率均为4-6%（p>0.05）。M2时的肌腱内改变与运动员的髌腱病相关（p≤0.01）。M1时的肌腱内改变、人体测量数据、训练量、运动项目或性别均不能预测腱病的发展（p>0.05）。青少年运动员中，跟腱腱病和肌腱内改变的发生率较低，髌腱则更常见。髌腱的肌腱内改变与腱病有关。然而，未能确定预测因素。
