• FAAM Calculator29 items
  Foot and Ankle Ability MeasureThe FAAM is a 29-item patient-reported questionnaire for musculoskeletal disorders of the leg, foot and ankle that produces two separate subscale scores — Activities of Daily Living from 21 items and Sports from 8 items — each expressed from 0% (unable to perform the listed activities) to 100% (no limitation).
• FAOS Calculator42 items
  Foot and Ankle Outcome ScoreThe FAOS is a 42-item patient-reported questionnaire adapted from the KOOS that scores foot and ankle problems as five separate subscales — Symptoms, Pain, Activities of Daily Living, Sport and Recreation, and Quality of Life — each from 0 (extreme problems) to 100 (no problems).

Clinical calculator1

• AOFAS Hallux Calculator8 items
  AOFAS Hallux Metatarsophalangeal-Interphalangeal ScaleThe AOFAS Hallux Metatarsophalangeal-Interphalangeal Scale is a 100-point clinician-administered rating of the great toe that combines 40 points for pain, 45 for function across six items and 15 for alignment — among the most widely reported outcomes after hallux valgus and hallux rigidus surgery, although the society that published it withdrew its endorsement in 2011 because it was never validated.
