Indication:
Knee injury
Findings
- Lateral position of the patella on the frontal view
- Small joint effusion
- Soft tissue swelling overlying the patella
- Approximately 1 cm cortical-based lucent lesion with sclerotic margins along the posterior aspect of the medial femoral condyle
Diagnosis
Lateral patellar dislocation
Non-ossifying fibroma
Sample Report
No acute fracture.
Lateral position of the patella on the frontal view, concerning for patellar dislocation, with overlying soft tissue swelling. A sunrise view would provide more definitive evaluation for dislocation.
Small joint effusion.
Approximately 1 cm cortical-based lucent lesion with sclerotic margins along the posterior aspect of the medial femoral condyle consistent with a non-ossifying fibroma (a benign lesion).
