The prevalence of jumper's knee among nonelite athletes from different sports is unknown.
This study was undertaken to determine the prevalence of jumper's knee in nonelite athletes from different sports and to determine potential risk factors for jumper's knee.
Cohort study (prevalence); Level of evidence, 2.
The authors interviewed 891 male and female nonelite athletes from 7 popular sports in The Netherlands: basketball, volleyball, handball, korfball, soccer, field hockey, and track and field. Using a specially developed questionnaire, information was obtained about individual characteristics (age, height, and weight), training background, previous and actual knee problems, and the VISA-P (Victorian Institute of Sport Assessment-Patella) score.
The overall prevalence of current jumper's knee was 8.5% (78 of 891 athletes), showing a significant difference between sports with different loading characteristics. Prevalence was highest among volleyball players (14.4%) and lowest among soccer players (2.5%); it was significantly higher among male athletes (51 of 502 [10.2%]) than female athletes (25 of 389 [6.4%]) (χ(2) = 3.91, P = .048). The mean duration of symptoms was 18.9 months (standard deviation [SD], 21.6; median value, 12.0; range, 2.0-59.8). The mean VISA-P score of the athletes with jumper's knee was 71.4 (SD, 13.8). Athletes with jumper's knee were significantly younger, taller, and heavier than those without jumper's knee.
Prevalence of jumper's knee is high among nonelite athletes and varies between 14.4% and 2.5% for different sports. Jumper's knee is almost twice as common among male nonelite athletes compared with female athletes. Different sport-specific loading characteristics of the knee extensor apparatus, a younger age, a taller body stature, and higher body weight seem to be risk factors associated with patellar tendinopathy.
不同运动项目的非精英运动员中跳跃膝的患病率尚不清楚。
本研究旨在确定不同运动项目的非精英运动员中跳跃膝的患病率，并确定跳跃膝的潜在危险因素。
队列研究（患病率）；证据水平，2。
作者对来自荷兰 7 种流行运动项目（篮球、排球、手球、曲棍球、足球、曲棍球和田径）的 891 名男性和女性非精英运动员进行了访谈。使用专门开发的问卷，获取了个人特征（年龄、身高和体重）、训练背景、既往和当前的膝关节问题以及 VISA-P（维多利亚运动评估-髌骨）评分等信息。
当前跳跃膝的总体患病率为 8.5%（891 名运动员中的 78 名），不同负荷特征的运动项目之间存在显著差异。排球运动员的患病率最高（14.4%），足球运动员的患病率最低（2.5%）；男性运动员（51/502[10.2%]）明显高于女性运动员（25/389[6.4%]）（χ²=3.91，P=.048）。症状持续时间的平均值为 18.9 个月（标准差[SD]，21.6；中位数，12.0；范围，2.0-59.8）。跳跃膝运动员的 VISA-P 平均得分为 71.4（SD，13.8）。有跳跃膝的运动员比没有跳跃膝的运动员年龄更小、更高、更重。
跳跃膝在非精英运动员中的患病率较高，不同运动项目的患病率在 14.4%至 2.5%之间。与女性运动员相比，男性非精英运动员中跳跃膝的患病率几乎高出一倍。膝关节伸肌装置的不同运动特异性负荷特征、更年轻的年龄、更高的身高和更高的体重似乎是与髌腱病相关的危险因素。
