1 Before you use it
What it is
KOOS adapted to the foot and ankle — same five subscales (pain, symptoms, ADL, sport and recreation, quality of life), same scoring logic, same family.
When to reach for it
Ankle and foot presentations where you want the five-subscale structure — including hallux rigidus, turf toe and post-fracture ankles.
2 Giving it
Scoring
Five subscales, each 0–100, reported separately. Higher is better.
What it doesn’t measure
Instability specifically, or dynamic balance.
3 Reading the score
Interpreting it
Interpret against baseline.
Choose it over FAAM when you want a quality-of-life subscale, or when the rest of your service is already using the KOOS family.
Is the change real?
Student trap. Running both FAAM and FAOS on the same patient. Pick one — they measure the same thing twice.
