AJRR’s 2022 Annual Report Details Trends in Joint Replacement in the US

The American Joint Replacement Registry (AJRR) now includes data on more than 2.8 million hip and knee arthroplasty procedures submitted by more than 1250 hospitals, ambulatory surgery centers (ASCs), and private practice groups in the US since 20212, making it the largest orthopaedic registry by annual procedure count.

The data are available in the AJRR’s recently published 2022 Annual Report, which details procedural trends and patient outcomes. Notable highlights in the report include:

  • ASCs play an increasingly important role in the delivery of total joint arthroplasty care in the US. The number of procedures submitted by ASCs has grown exponentially between 2012 and 2020 and has increased by 57% since the 2021 AJRR Annual Report.
  • Trends in the utilization of technology in total knee arthroplasty (TKA) and total hip arthroplasty (THA) were a new addition to this report. Utilization of robotics in TKA has increased more than six-fold and more than doubled in THA since 2017. Computer navigation use has remained relatively stable.
  • Patient-reported outcome measures (PROMs) are increasingly being utilized to evaluate success of a hip or knee arthroplasty procedure. Through continued support of the RegistryInsights PROM platform and partnerships with third-party vendors, AJRR has experienced substantial growth in PROMs capture. By the end of 2021, more than 400 participating sites submitted PROMs, which is a 38% increase compared with the previous year.
  • For the first time this year, age-stratified patient-reported outcome scores were evaluated. Patients older than 75 years of age were found to have poorer scores compared with younger patients, most notably on the PROMIS-10 quality of life assessment tool.
