Abstract
Patellar dislocation is commonly seen in the pediatric population, and its presentation can be quite unnerving to patients and parents alike. Often, the injury is initially reported as a dislocated knee, but this is not the case. Patellar dislocations do not require significant force to occur and they are relatively easy to reduce. While imaging can help confirm the diagnosis, in cases of patellar dislocation, initial imaging prior to reduction is not indicated unless there is concern for a more serious injury, such as a knee dislocation or fracture. Once the dislocation is reduced, imaging is appropriate to evaluate for accompanying fractures. Plain radiography is the imaging modality of choice; computed tomography and magnetic resonance imaging are not typically indicated in the acute setting.
