📌Sinding-Larsen-Johansson Syndrome
- Sinding-Larsen-Johansson syndrome, also known as jumper's knee, is caused by repetitive microtrauma to the patellar tendon at its attachment on the inferior pole of the patella.
✅ Etiology
- This syndrome is a type of traction apophysitis that occurs at the inferior pole of the patella.
- In contrast, Osgood-Schlatter disease is traction apophysitis at the tibial tubercle.
✅ Imaging Findings
- Chronic traction can lead to heterotopic ossification, which is identifiable through imaging.
- MRI typically shows edema at the inferior pole of the patella and in the proximal portion of the patellar tendon and surrounding soft tissues.
