Background The quadriceps angle (Q angle) is measured as an angle formed by two lines that extend from the anterior superior iliac spine to the midpoint of the patella and from the midpoint of the patella to the tibial tuberosity. The average Q angle value for children aged between seven to 12 years was 13.1˚±3.5˚in boys and 13.7˚±4.9˚ in girls, whereas 8˚-15˚ in men and 12˚-19˚ in women. Abnormal variation in Q angle is associated with patellofemoral pain syndrome, lateral patellar malposition, dislocation, chondromalacia patella, patella alta, genu varum, etc. Methodology The present study explores the status of Q angle values among adolescents with short stature and their comparison with age and gender-matched children between 10 and 15 years of age. Results We found a statistically significant difference between the Q angle value in the control group and the male with short stature group aged 14-15 years, with a mean difference of 3.7˚. However, among females, there was a significant difference between the control group and the short-stature group aged 12-13 and 14-15 years, with a mean difference of 2.8˚ and 2.5˚, respectively. Implications Early detection and timely remedial measures, e.g., quadriceps strengthening exercises, before skeleton maturity can prevent Q angle-related misalignments and abnormalities in the limb.
股四头肌角（Q角）是由从髂前上棘延伸至髌骨中点的线与从髌骨中点延伸至胫骨结节的线所形成的角度。7至12岁儿童的平均Q角值，男孩为13.1˚±3.5˚，女孩为13.7˚±4.9˚，而男性为8˚ - 15˚，女性为12˚ - 19˚。Q角的异常变化与髌股疼痛综合征、髌骨外侧位置异常、脱位、髌骨软骨软化症、高位髌骨、膝内翻等有关。方法：本研究探讨身材矮小青少年的Q角值状况，并将其与10至15岁年龄和性别匹配的儿童进行比较。结果：我们发现对照组与14 - 15岁身材矮小男性组的Q角值存在统计学显著差异，平均差值为3.7˚。然而，在女性中，对照组与12 - 13岁和14 - 15岁身材矮小组之间存在显著差异，平均差值分别为2.8˚和2.5˚。意义：在骨骼成熟前进行早期检测并及时采取补救措施，如股四头肌强化锻炼，可预防与Q角相关的肢体排列不齐和异常。
