The American Joint Replacement Registry (AJRR), the cornerstone of the American Academy of Orthopaedic Surgeons (AAOS) Registry Program, is proud to present its 2022 Annual Report on hip and knee arthroplasty procedural trends and patient outcomes. The ninth annual report demonstrates an overall cumulative procedural volume growth of 14% compared to the previous year and includes over 2.8 million hip and knee procedures since 2012 from over 1,250 hospitals, ambulatory surgery centers (ASCs), and private practice groups submitting data.

The members of the International Society of Arthroplasty Registries (ISAR) have a shared purpose of improving outcomes for individuals receiving hip and knee replacement surgeries worldwide. The focus of the society is to motivate worldwide cooperation to share medical device information. These collective efforts will assist in enhancing the quality of local registries and expanding the capacity of data-use related projects. The society is involved in the development of frameworks to encourage collaborative activities and provide a support network for established and developing registries. The AAOS American Joint Replacement Registry (AJRR) is a member of ISAR and participates at the Annual International Congress of Arthroplasty Registries each year.

The following AJRR data-based abstracts were accepted at the 10th Annual Virtual International Congress of Arthroplasty Registries in 2021. Additionally, this was the first year that an AAOS staff member presented at the congress regarding the progress of the International Prosthesis Library.

A study that sought to determine what factors predict total joint arthroplasty (TJA) outcomes at one year found that among patients in the American Joint Replacement Registry (AJRR) for whom patient-reported outcome measures (PROMs) had been recorded, preoperative PROMs, especially physical function subscores, predicted improvement at one year.

The Annual Report of the Academy’s American Joint Replacement Registry (AJRR), released at the Annual Meeting of the American Association of Knee and Hip Surgeons (AAHKS) in November 2020, tells the story of a year marked by a multitude of successes and growth for AJRR.

The American Academy of Orthopaedic Surgeons (AAOS) released a new report based on clinical data from hip and knee arthroplasty patient outcomes as part of the American Joint Replacement Registry (AJRR), the largest orthopaedic registry in the world based on annual procedures submitted. Based on the sixth AJRR Annual Report on hip and knee arthroplasty data, the new resource highlights the information that is most relevant for patients and the public. It aims to help those outside the orthopaedic profession learn more about hip and knee replacement procedures and better understand how registry data can help to inform decisions and improve patient care.

The American Joint Replacement Registry (AJRR), the cornerstone of the American Academy of Orthopaedic Surgeons (AAOS) Registry Program, released its 2020 Annual Report on hip and knee arthroplasty patient outcomes. AJRR is the largest orthopaedic registry in the world based on annual procedures submitted, and the analysis provides insight into U.S. hip and knee arthroplasty practice. The Annual Report, released in conjunction with the first day of the American Association of Hip and Knee Surgeons’ (AAHKS) 2020 Annual Meeting, includes findings from 1,897,050 hip and knee arthroplasty procedures performed between 2012 and 2019, representing an overall cumulative procedural volume growth of 24.4% compared to the previous year.

The AAOS Registry Analytics Institute® gives clinicians and clinician scientists the opportunity to submit hypotheses about information in AAOS registries. Those with approved proposals receive AAOS analytics insights and committee guidance. Read on for a summary of two recent projects using analyses from the American Joint Replacement Registry (AJRR), AAOS' hip and knee arthroplasty registry.

When the question is, “What’s new with the AAOS Registry Program?” a safe answer is always, “Plenty!”

The AAOS Family of Registries is an ever-growing clan, both in numbers of anatomically categorized programs and in the volume and quality of data that continue to pour into these valuable clinical data repositories for orthopaedic procedures. Also growing are the ways the data can be used to improve the quality and value of care.

This blog is the final installment in a three-part series reporting on orthopaedic studies presented at the 2019 American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting and utilizing American Joint Replacement Registry (AJRR) registry data. All presentations are reported by Terry Stanton, senior science writer for AAOS Now.

Paper 878, “Correlation of Perioperative Periprosthetic Femur Fractures with Fixation Method” was presented by Bryan D. Springer, MD, vice chair of AJRR, on Friday, March 15, 2019 at the AAOS Annual Meeting in Las Vegas, Nevada. The study evaluated data from the AJRR over a five-year period and analyzed the relationship between femoral stem fixation and perioperative periprosthetic femur fracture (PPFx) requiring early revision total hip arthroplasty (THA) surgery. Analyses determined that cementless femoral fixation accounted for 93 percent of stems with early PPF. Dr. Springer said that patients with cementless stems were 2.6 times more likely to undergo early revision for PPF than those with cemented fixation, although the number of cemented stems in the analyzed population was small, making that finding not statistically significant.
