- Radiographs should be routinely ordered to rule out fractures. Knee injuries in children less than 14 years of age are more commonly seen than ligamentous injuries.
- AP and lateral views are adequate for most cases, but infrapatellar or "sunrise" view is recommended if patellar dislocation or fracture is suspected.
- All reductions should be confirmed radiographically to rule out association fractures.
