Quick knee checks.
Three simple checks. Nothing asks for your name or details, and nothing gives a diagnosis.
For healthcare professionals
Does this injured knee need an X-ray?
Answer each question for an acute knee injury in an adult. The result updates as you go. Nothing is stored or sent.
Age 55 or older
Isolated tenderness of the patella (no other bony tenderness)
Tenderness at the head of the fibula
Unable to flex to 90°
Unable to bear weight both immediately and at assessment (four steps)
Result
Answer the five questions
Any one “Yes” means the rule suggests an X-ray. An X-ray can be ruled out by the rule only when all five are “No”.
Applies to acute knee injuries in adults. A decision aid, not a substitute for clinical judgement.

Every treatment has one goal: movement.
bend
Standing straight
Everyday activities need different amounts of bend.
Sports knee
Do you need an MRI?
