A new patellar angle is described in lateral radiographs of the knee joint. One line is drawn along the articular surface of the patella and another from the end of the inferior articular cartilage to the patellar apex. The angle formed by these two lines averaged 33 degrees in 68 knees joints afflicted with Osgood-Schlatter disease and 47 degrees in 71 age-matched controls and 198 adult controls. The small angle in Osgood-Schlatter disease is proposed to be an important factor in the pathogenesis of the traction apophysitis.
膝关节侧位X线片上描述了一种新的髌角。一条线沿髌骨的关节面绘制，另一条线从下关节软骨末端至髌骨尖。在68例患有奥斯古德-施拉特病的膝关节中，这两条线形成的角度平均为33度，在71例年龄匹配的对照组和198例成人对照组中为47度。奥斯古德-施拉特病中的小角度被认为是牵引性骨突炎发病机制中的一个重要因素。
