Comparison of the European Foot and Ankle Score (EFAS) and the Self-Reported Foot and Ankle Score (SEFAS) in patients with foot and ankle surgery.

Background: The European Foot and Ankle Score EFAS and the Self-reported Foot and Ankle Score SEFAS are two Patient Reported Outcome Measures (PROMs) used in foot and ankle surgery. The EFAS has been published in recent years, while the SEFAS is a validated questionnaire based on the New Zealand total ankle questionnaire.

Methods: We compared the EFAS to the SEFAS, Short Form 36 (SF-36) and Numeric Rating Scale (NRS) regarding reliability and validity based on the results of 126 patients undergoing foot and ankle surgery in a single center.
