Directed by the California State Registry Committee (CSRC) to monitor the progress and participation of California sites, the new California-specific registry supplement continues the work originally established by the California Joint Replacement Registry (CJRR). This report focuses on the 30 original CJRR sites for which there were 303 unique surgeons with a valid surgeon ID for these analyses. In total, the California State Registry Supplement comprises of 57,246 unique hip and knee cases from 2012 through 2018.

“The new data coming out of the AAOS are impressive and an exciting extension of the American Joint Replacement Registry's first annual report which debuted in 2019,” said Bryan D. Springer, MD, FAAOS, chair of the AJRR Steering Committee. “Each report was made possible by the successful integration of administrative claims data into AJRR, which provides a more complete picture of our patient population and their associated comorbidities and outcomes, including longitudinal outcomes of patients who receive care at non-AJRR participating sites.”
