本文用临床流行病学方法调查了我国111名优秀男子排球运动员髌骨软骨软化症(CP)的患病情况及与Q角的关系,发现CP患病率达39.6%,占膝伤首位。111名男排队员的平均Q角为13°±3°,其中44例患者的Q角为14°±3°,较未患CP者的Q角12°±3°明显为大。CP患病率与Q角大小密切正相关,r=0.825。认为Q角在发育成熟的个体较恒定,建议作为运动员选材的指标之一。同时也探讨了Q角测量方法、认为体表定位Q角测量是一种简单易行,精确可靠的方法。选取髌骨中点是保证精确测量的关键。
In this paper, the prevalence of patellar chondromalacia (CP) in 111 male eldest volleyball players in China and its relationship with Q angle were investigated by clinical epidemiology. The prevalence of CP was 39.6%, accounting for the first place of knee injury. The average Q angle of 111 male squadrons was 13 ° ± 3 °, of which 44 patients had a Q angle of 14 ° ± 3 ° and a significantly larger Q angle of 12 ° ± 3 ° than those who did not. The prevalence of CP was closely related to the size of Q angle, r = 0.825. It is considered that the angle Q is more constant in mature individuals and is suggested as one of the indexes for selecting athletes. At the same time, the method of Q angle measurement is also discussed. It is considered that Q angle measurement of body surface positioning is a simple, accurate and reliable method. Patellar midpoint selection is the key to ensure accurate measurement.
