Pediatric Case 9 Diagnosis

OSD is a clinical diagnosis. X rays are not required, unless an acute avulsion fracture is suspected. While patients with Osgood-Schlatter's disease present with insidious progressive pain, those with acute avulsion fractures have an acute onset of pain associated with an injury. Consider other causes for knee pain in patients with erythema, pain at night, or acute injury.

The typical radiographic finding in OSD is irregular ossification of the tibial tubercle.
