Cases Solved! is a journal-based CME activity series presented by the American Academy of Orthopaedic Surgeons.

Each activity consists of an interactive clinical case scenario based on a recent article from the Journal of the American Academy of Orthopaedic Surgeons (JAAOS) followed by a multiple-choice assessment to put your diagnostic and management skills to the test.

These current, peer-reviewed articles touch on important areas of orthopaedic patient care and describe how the article impacts practice behavior and/or systems of care.
