To report point prevalence of anterior knee pain (AKP) in adolescent athletes by (1) maturation status, (2) chronological age, (3) sex, and (4) primary sport.
Cross-sectional.
Male and female participants aged 11-15 years were recruited from specialised sports programs for basketball, volleyball, Australian Rules Football and tennis. Standing height, sitting height, and body mass were measured and used to calculate maturity status. Past injury history, self-reported physical activity, and Victorian Institute of Sport Assessment Questionnaire Patellar Tendon (VISA-P) questionnaires were completed. Anterior knee pain was defined as any pain experienced on the anterior surface of the knee and recorded using a visual analogue scale (VAS). A single leg decline squat (SLDS) was performed for provocation of AKP.
Two hundred and seventeen male and female adolescent athletes participated in this study. Twenty participants were excluded from data analysis. Point prevalence of AKP was 39% (N = 76). Average self-reported physical activity/week was 7.9 ± 4.1 h of their specialised sport and 2.0 ± 2.0 h of other physical activity/week. Maturation status, chronological age, sex nor primary sporting program was statistically significant in explaining the presence or absence of AKP.
Due to the right-skewed maturation sample, the authors cannot state conclusively that maturation status was not associated with AKP. Nearly 40% of this cohort reported AKP during a pain provocation test. The presence of AKP was not explained by maturation status, age, sex or primary sport program. Given the chronic nature of AKP and future morbidity reported, this high prevalence provides rationale for intervention or prevention studies targeting younger athletes.
通过（1）成熟度、（2）年龄、（3）性别和（4）主要运动项目，报告青少年运动员前膝痛（AKP）的时点患病率。
横断面研究。
从篮球、排球、澳式足球和网球专项运动项目中招募 11-15 岁的男性和女性参与者。测量站立身高、坐高和体重，并用于计算成熟度。完成既往损伤史、自我报告的身体活动和维多利亚州运动评估协会髌腱问卷（VISA-P）。前膝痛定义为膝关节前表面出现的任何疼痛，并使用视觉模拟量表（VAS）记录。单腿下降蹲（SLDS）用于诱发 AKP。
本研究共有 217 名男性和女性青少年运动员参加。20 名参与者被排除在数据分析之外。AKP 的时点患病率为 39%（N=76）。平均自我报告的每周专项运动身体活动/周为 7.9±4.1 小时，其他身体活动/周为 2.0±2.0 小时。成熟度、年龄、性别或主要运动项目在解释 AKP 的存在与否方面均无统计学意义。
由于成熟度样本呈右偏态分布，作者不能确定成熟度与 AKP 无关。该队列中近 40%的人在疼痛诱发试验中报告有 AKP。AKP 的存在不能用成熟度、年龄、性别或主要运动项目来解释。鉴于 AKP 的慢性性质和未来报告的发病率，这种高患病率为针对年轻运动员的干预或预防研究提供了依据。
