CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this quiz assess?
It reviews urgent warning signs, changes in movement or stability, and whether symptoms are improving or worsening. It does not diagnose a specific injury.
How long does it take and how many questions are included?
It includes 15 questions and typically takes about 10 minutes to complete.
When is urgent medical care needed?
Seek urgent help now for a deformed knee, an open wound, a cold or discolored foot, new weakness or numbness, or chest pain or breathing difficulty. Do not wait for a score if any of these are present.
How should the results be interpreted?
The score bands are unvalidated reflective summaries rather than medical cutoffs. Use the results to consider how promptly to consult a clinician or knee specialist.
What time period should be used when answering?
Answer based on current symptoms and any change since the injury or the most recent flare. If unsure, select the option that best matches the typical or most severe pattern.
