为了解髌骨的正常位置及正常值,我们对100例(男性60例,女性40例)成人髌骨在膝关节正位X线片上进行了测量。测量方法及结果:1.作股骨下端关节面的切线(即内外髁下极两点的连线)。2.从髌骨底边缘最远点作股骨下端关节面切线的垂线。垂线长度为髌骨高度(见附图)。取毫米值,男性为42～60mm,平均 In order to understand the normal position and normal position of the patella, we measured 100 cases (60 males and 40 females) of adult patella on the orthopedic knee X-ray. Measurement methods and results: 1 for the femoral articular surface of the tangential (ie the medial and lateral condyle two connections). 2. From the farthest edge of the bottom edge of the patella for the femoral articular surface tangent of the vertical line. Vertical length of the patella height (see photo). Take millimeters, male 42 ~ 60mm, average
