As part of its mission, the American Board of Orthopaedic Surgery (ABOS) is responsible for setting educational and performance standards for orthopaedic surgery residents. Traditionally, the success of residents has been measured by them performing rotations of set-lengths. Partnering with residency programs, the ABOS is working on a Knowledge, Skills, and Behavior program to better measure the competency of orthopaedic surgeons which ultimately protects the public.
