DESCRIPTION OF THE INSTRUMENT
Type Of Measure Scale
Brief Description

The AOFAS Clinical Rating Scales are four separate outcome measures that evaluate different anatomic regions of the foot and ankle: the ankle/hindfoot (AOFAS‐AH), the midfoot (AOFAS‐M), the hallux metatarsophalangeal‐interphalangeal (AOFAS‐HJ), and the lesser metatarsophalangeal‐interphalangeal (AOFAS‐LJ). Each outcome measure evaluates pain (one item), function (five to seven items) and alignment (one item).

Number of Items AOFAS‐AH: nine items; AOFAS‐M: seven items; AOFAS‐HJ: eight items; and AOFAS‐LJ: eight items.
Range 0-100
Responses options/scale Yes
Combination of subjective patient‐reported items (3‐ or 4‐point Likert scales) and clinician‐led objective measures (2‐ to 3‐point Likert scales)
Developed for ---
PRACTICAL APPLICATION
Method of administration Self-administered, Physician
Recommendations to score

Each item is scored from 0 (representing the worst foot status) to scores that range from 5 to 40, depending on the item (representing the best foot status). The items are summed to give a total score of 100.

Score Interpretation Total scores range from 0 (representing the worst foot status) to 100 (representing the best foot status).
