Pediatric Case 9 Background

Osgood-Schlatter's Disease

Osgood-Schlatter's Disease (OSD) is an overuse injury that typically occurs in children age 9-14 with a male predominance. The repetitive strain from running, basketball, or other repetitive sports leads to chronic avulsion of the apophysis of the tibial tubercle. Chronic microfractures cause separation of patellar tendon from the tubercle, leading to callous formation and a prominent tender tibial tuberosity.
