Morphological variants of the suprapatellar septum. An anatomical study in neonatal cadavers.

In order to study the incidence and variations of the suprapatellar septum, 100 knee joints of 50 neonatal cadavers were examined anatomically. In 26% of the neonatal knee joints, a complete septum was found. Perforated septa with different shapes and residual septa were seen in 64% knees. A complete involution of the former septum was found in 10 of our cases. A suprapatellar septum combined with a mediopatellar plica was found in 18 knees.
