 Background: American Orthopedic Foot and Ankle Society Score (AOFAS) is a reliable and reproducible measurement tool which is commonly used for the assessment of foot and ankle conditions. In this study we aimed to translate and assess the psychometric properties of the Persian version of AOFAS questionnaire. Methods: In this study, we enrolled 53 patients with ankle and hindfoot conditions. Our study was conducted according to five staged cross-cultural adaption steps including translation, synthesis, back translation, expert committee review, and pretesting. After that reliability of the subjective parts calculated by Cronbach�s alpha and the intraclass correlation coefficient (ICC) and the reliability of the objective items estimated using Cohen�s kappa test. Also, construct validity was assessed by testing the Persian AOFAS against the SF-36 questionnaire. Results: Chronbach�s alpha coefficient was 0.696, which was considered acceptable. Furthermore, the test-retest reliability measured by using the ICC for the subjective subscales was 0.853 (P<0.001). The reliability of testing the objective subscales was calculated by using Kappa, which indicated acceptable values. Pearson correlation coefficient between AOFAS and SF-36 was 0.415 (P=0.008). In addition, floor and ceiling effects were calculated 1.9 and 7.5 respectively. Conclusion: In our study, Persian translation of AOFAS demonstrated acceptable validity and reliability with no need to be culturally adapted. Level of evidence: II
