Previous studies on the quadriceps (Q) angle and its relation to knee problems have led to conflicting conclusions. In this comprehensive review, we evaluate recent studies on the Q angle and analyze the changes in Q angles. Specifically, we investigate the variation in Q angles when measured under the following conditions: 1) under various measurement techniques; 2) between symptomatic and non-symptomatic groups; 3) between samples of men and women; 4) unilateral versus bilateral Q angles; 5) Q angle in adolescent boys and girls. It is widely believed that Q angles are more significant in symptomatic patients than in asymptomatic individuals or that the right lower leg and left lower limb are equivalent, which is supported by little scientific data. However, research states that young adult females have higher mean Q angles than males.
先前关于股四头肌（Q）角及其与膝关节问题关系的研究得出了相互矛盾的结论。在这篇综述中，我们评估了近期关于Q角的研究，并分析了Q角的变化。具体而言，我们研究了在以下条件下测量Q角时的变化：1）在各种测量技术下；2）有症状组和无症状组之间；3）男性和女性样本之间；4）单侧与双侧Q角；5）青少年男孩和女孩的Q角。人们普遍认为，Q角在有症状的患者中比在无症状的个体中更显著，或者右下肢和左下肢是等效的，但几乎没有科学数据支持这一点。然而，研究表明，年轻成年女性的平均Q角高于男性。
