Osgood-Schlatter disease in ultrasound diagnostics--a pictorial essay.

This paper tries to describe reasons, pathophysiological sequence of events, including the sequelae, and location of the traumatic tears of the ossification center of the tibial tuberosity in adolescents. Ultrasonographic features characteristically seen in the traction type of Osgood-Schlatter disease (OSD) are presented in a pictorial. The classification and definitions used are based on the three types of OSD described by Czyrny and Greenspan in 2009.
