- Isolated tenderness of the patella
- Tenderness at the fibular head
- Inability flex to 90 degrees
- Inability to walk 4 steps BOTH immediately after the injury and in the ED
Caveats
- 99% sensitive in children OVER age 5[6]
- Beware of the Tillaux Fracture in adolescents with anteromedial ankle pain, as they would not qualify for imaging according to this rule.
