Is AOFAS clinician-administered or self-reported?

AOFAS is partially clinician-administered (alignment and range of motion items) and partially patient-reported (pain, activity limitation). This mixed nature reduces its validity as a purely patient-reported outcome measure in modern trials.

What AOFAS score defines good outcome?

AOFAS 75-100 = excellent-good. Score <75 = fair-poor. Total ankle arthroplasty achieves mean AOFAS improvement of 30-40 points. Ankle fusion achieves 25-35 points improvement. Both exceed the 10-12 point MCID.

Is AOFAS recommended by outcome registries?

AOFAS has been criticized for poor psychometric properties and declining use in high-quality trials. FAAM and PROMIS Foot and Ankle are preferred by the Foot and Ankle Outcomes Consortium. However, AOFAS remains widely used for comparisons with historical data.
