Assessment of Osgood-Schlatter Disease and the Skeletal Maturation of the Distal Attachment of the Patellar Tendon

Background: Osgood-Schlatter disease (OSD) is a traction apophysitis of the tibial tuberosity. Ultrasonography (US) is able to detect pathologic changes, such as cartilage swelling and fragmentation of the tibial tubercle ossification center. Purpose: To compare the US stages of tibial tuberosity development and the physical features and prevalence of OSD in this patient cohort. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Subjects included 238 males (n 476 joints) with a mean age of 11.4 ± 1.6 years (range, 7-14 years). The tibial tuberosit
