The American Joint Replacement Registry released its 2020 Annual Report, which includes findings from 1,897,050 hip and knee arthroplasty procedures performed between 2012 and 2019.

According to a press release, the 2020 Annual Report represents an overall cumulative procedural volume growth of 24.4% compared the previous year. It marks the seventh annual report released by the American Joint Replacement Registry.

“As the definitive chronicle of joint replacement in the United States, this year’s [American Joint Replacement Registry AJRR Annual Report continues to build on previous work and demonstrates the incredible value of the AJRR,” James A. Browne, MD, FAAOS, chair of the AJRR Publications Subcommittee and editor of AJRR Publications, said in the release. “More sophisticated and detailed survivorship curves have been included this year, including device-specific cumulative revision curves. The breadth of data reporting has also been expanded, and now includes analyses of topics such as type of anesthesia, discharge disposition and body mass index.”

The 2020 Annual Report also showcases new or enhanced registry capabilities and offerings including:

  • Use of cumulative incidence of revision curves to examine survivorship
  • The addition of component specific statistical summaries displaying common components in hip and knee arthroplasties as well as device-specific cumulative percent revision curves as presented in the 2019 AJRR Annual Report Supplement
  • Additional opportunities for sites to track performance measurements and use registry data in national quality improvement programs
  • Through the continued support of the RegistryInsights patient-reported outcome measure platform and partnerships with third party vendors with the expanded Authorized Vendor Program, the 2020 Annual Report has a 13% increase in patient-reported outcome measures compared the previous year
  • Peer-reviewed publications and presentations based on AJRR Registry data

“The COVID-19 pandemic has led to unprecedented times in the United States and the world—yet the AJRR and the development of the [American Academy of Orthopedic Surgeons AAOS family of registries continue to see unparalleled growth and expansion,” Bryan D. Springer, MD, FAAOS, chair of the AJRR Steering Committee, said in the release. “This success is a tribute to the nation’s understanding of the fundamental importance of national registries, but also to the value that our registry brings to surgeons, hospitals and other stakeholders every day. Our procedural growth (over 2 million and counting) is rivaled by continued growth of data reuse opportunities for participation in multiple public and private value-based care incentive programs. I look forward to continued expansion and growth of all these opportunities.”

The complete 2020 Annual Report can be read on the AJRR website, along with slides with figures and data tables as feature in the report.
