American Academy of Orthopedic Surgeons (AAOS) American Joint Replacement Registry (AJRR) registry programs have an annual data specification release and sunset cycle. The annual data specification release and sunset cycle provide simplification of the data transition process. The release and sunset cycle allows clinicians to understand the timeline for new releases of data elements and when the oldest specifications will be removed from registry submission eligibility.
