The patella is located lateral to its expected position. No fracture.
Case Discussion
The patella has dislocated laterally. This is often a transient phenomenon with spontaneous reduction before the patient attends the ED. MRI can show damage to the medial retinaculum and marrow edema within the patella and lateral femoral condyle.
