To compare knee torque, range of motion, quality of movement, and morphology in dominant and nondominant legs of male adolescent basketball players with and without anterior knee pain and untrained peers.
Cross-sectional.
Sports performance laboratory.
Male basketball players aged 14-15 years with and without anterior knee pain and healthy untrained subjects (n = 88).
Basketball players were allocated to a symptomatic or asymptomatic group based on self-reported anterior knee pain. Associations between pain and body mass, height, passive range of motion, muscle peak torque, coactivation, neuromuscular control, proprioception, and ultrasound observations were investigated.
The prevalence of pain did not differ significantly between sides. Of 176 knees inspected, 44 were painful, and 26 of these exhibited abnormalities in ultrasonography. Symptomatic players were 5.0 and 6.9 cm taller than asymptomatic players and controls, respectively (P < 0.05). In athletes with knee pain, the odds ratios of morphological abnormalities and greater height were increased by 8.6 and 5.0 times (P < 0.001).
Knee pain prevalence in adolescent basketball players was not related to differences between sides but was higher in tall players. Knee pain was accompanied by morphological abnormalities detected with ultrasound.
比较有和无膝关节前痛的男性青少年篮球运动员及未经训练的同龄人的优势侧和非优势侧膝关节的扭矩、运动范围、运动质量和形态。
横断面研究。
运动表现实验室。
年龄在 14-15 岁的男性篮球运动员，分为有膝关节前痛和无症状组以及健康的未训练组（n=88）。
根据自我报告的膝关节前痛，将篮球运动员分为有症状或无症状组。研究了疼痛与体重、身高、被动运动范围、肌肉峰值扭矩、共激活、神经肌肉控制、本体感觉和超声观察之间的关系。
疼痛的发生率在两侧之间无显著差异。在检查的 176 个膝关节中，44 个有疼痛，其中 26 个在超声检查中出现异常。有症状的运动员比无症状运动员和对照组分别高 5.0 和 6.9cm（P<0.05）。在有膝关节疼痛的运动员中，形态异常和身高较高的比值分别增加了 8.6 倍和 5.0 倍（P<0.001）。
青少年篮球运动员膝关节疼痛的发生率与两侧之间无差异，但在高个子运动员中更高。膝关节疼痛伴有超声检测到的形态异常。
