"The ability to return to normal procedural volume rates just a few months after the COVID-19 pandemic began is a testament to the commitment and resiliency of healthcare institutions, clinicians and patients. While we are experiencing unprecedented times in healthcare and continue to navigate the challenges of the pandemic, the AJRR remains committed to the growth and expansion of the registry to paint a more complete picture of our patient population. Through increased participation and a successful integration of Medicare claims data, we are providing orthopaedic surgeons, hospitals and stakeholders with actionable data, insights and trends to improve the lives of millions of Americans who suffer from hip and knee arthritis."

AJRR Steering Committee Chair 


"This year's AJRR Annual Report provides the most comprehensive picture to date of patterns of hip and knee arthroplasty practice and outcomes in the United States. For the first time this year, cumulative percent revision curves were produced with a diagnosis-specific endpoint examining revision due to infection for total knee arthroplasty (TKA) and revision due to periprosthetic fracture for total hip arthroplasty (THA) patients over 65 years of age. The Registry continues to use more sophisticated and detailed survivorship curves, including device-specific cumulative revision stratified by bearing and fixation type, in addition to utilizing Centers for Medicare & Medicaid Services (CMS) data."
