Both knees of 50 normal children aged from birth to 18 years were examined by ultrasonography to measure the angles of the bony intercondylar and the cartilaginous sulcus on the patellar surface of the femur. The osseous angle was inversely related to the age of the child and was completely flat in the youngest children. During growth it gradually gained depth to assume the shape of the overlying articular cartilage by adolescence. At all ages, however, the angle of the cartilaginous sulcus was between 134 degrees and 155 degrees. This suggests that the configuration of the patellar articulation is already well developed at birth.
对50名年龄从出生到18岁的正常儿童的双膝进行超声检查，以测量股骨髌面的骨性髁间角和软骨沟角。骨角与儿童年龄呈负相关，在最小的儿童中完全平坦。在生长过程中，它逐渐加深，到青春期时呈现出覆盖其上的关节软骨的形状。然而，在所有年龄段，软骨沟角在134度至155度之间。这表明髌骨关节的形态在出生时就已经发育良好。
