Abstract

Embryology.  —Haxton473 investigated the relative patellar breadth in two hundred and thirty-four mammalian limbs, including specimens from representatives of the principal orders, and reached the following conclusions: 1. The "patellar index" is not related to the size or the speed of movement of an animal. 2. There is no evidence that the patella is undergoing phylogenetic retrogression. 3. There is evidence that it has a functional value in extending the knee joint.Schifino and Griffo474 reported a case of trauma of the knee in which there was a separate fragment at the superior and lateral border of the patella. Roentgenographic examination of the opposite knee disclosed the same change. They note that Thurston Holland regarded this as an abnormality due to rickets and that Mouchet and Fornier thought that it was an apophysitis like that which occurs in osteochondrosis of tuberosity of the tibia (Osgood-Schlatter's disease).
