The American Orthopaedic Foot & Ankle Society (AOFAS) is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education (CME) for physicians. AOFAS designates blended AOFAS/IFFAS Scientific Session (live activity and enduring materials), for a maximum of 66.5 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

Successful completion of this CME activity, which includes participation in the evaluation component, enables the learner to earn credit toward the CME requirements of the American Board of Orthopaedic Surgery's Maintenance of Certification program. It is the CME activity provider's responsibility to submit learner completion information to ACCME for the purpose of granting ABOS credit.

Attendees may claim up to 66.5 continuing education credits total for the AOFAS Annual Meeting and IFFAS Biennial Meeting. Virtual attendees can earn up to 28.75 credits from live streamed sessions, and an additional 37.75 credits OnDemand by viewing concurrent programming after the meeting. Credits should be claimed upon completion of all educational programming.
