Discussion of Osgood-Schlatter disease
- Osgood-Schlatter disease is a chronic avulsion injury of the tibial tubercle.
- Thought to result from repetitive microtrauma and traction on the tibial tubercle
- Osgood-Schlatter disease is typically seen in active adolescents, particularly those who participate in sports that require jumping, squatting, and kicking.
- Can be bilateral in up to 50% of patients.
- Boys tend to be affected more often than girls.
- Patients present with localized pain, swelling, and tenderness.
- Diagnosis is most often made clinically.
 Imaging Findings for Osgood-Schlatter disease
- Radiographs shows fragmentation of the tibial tubercle, although this finding alone may represent a normal ossification center.
- MR imaging findings include
- Soft-tissue swelling anterior to the tibial tuberosity
- Loss of the sharp inferior angle of the infrapatellar fat pad and surrounding soft tissues
- Thickening and edema of the inferior patellar tendon
- Infrapatellar bursitis
