American Joint Replacement Registry Sees Remarkable Growth in 2025

The American Joint Replacement Registry (AJRR) has recently published its 12th Annual Report, revealing significant advancements in its growth and the data methodologies that are reshaping the future of arthroplasty care. The report stands as a testament to the increased volume of joint replacement procedures and the enhanced collaboration among medical institutions and experts globally.

Key Highlights of the 2025 Report

The AJRR recorded over 4.4 million hip and knee arthroplasty procedures from 2012 to 2024, reflecting an impressive 8.8% growth compared to the previous year. This increase emphasizes the AJRR's position as the largest orthopaedic registry in the world, based on its annual procedural count, which now exceeds a staggering 4.6 million cumulative procedures.

According to Dr. James I. Huddleston, III, the chair of the AJRR Steering Committee, this year’s report marks a continued trajectory of growth, establishing the registry as a premier national and global resource. He stated, “By collecting and analyzing real-world patient data from millions of procedures, the Registry is driving evidence-based decisions that advance quality initiatives.”

Advancements in Data and Research Methodologies

The report details several advancements in data methodologies and analytics. Key improvements include:

• - Collection of patient-reported outcome measures (PROMs) from 751 institutions, a 19% increase from the prior year.
• - Analytical focus on crucial metrics such as Minimal Clinically Important Difference (MCID), Substantial Clinical Benefit (SCB), and Patient Acceptable Symptomatic State (PASS).
• - Adoption of the Kaplan-Meier survival analysis method, providing a more accurate depiction of revision risk over time, replacing the previously utilized Cox model.
• - Expanded analysis of robotic-assisted surgeries, tracking specific utilization trends by manufacturer and highlighting the increasing role of technology in arthroplasty.

Collaboration with Industry and Academia

The AJRR's growth also reflects robust collaboration between industry and academic institutions. Over 80 custom analyses were completed for industry sponsors, partnered efforts resulted in expanded relationships with renowned organizations such as The Hip Society and The Knee Society. This collaboration aims to leverage the power of data for better patient outcomes and to set best practices in joint replacement care.

Strengthening Global Collaboration Efforts

Another significant aspect of this year’s report is the AJRR’s expanding involvement in international registry collaboration. The organization has been actively working with the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) and the International Society of Arthroplasty Registries (ISAR). Their combined efforts are contributing to global data-sharing initiatives and the development of the International Prosthesis Library (IPL), aiming to standardize implant performance evaluations and accelerate clinical innovation globally.

About the AJRR and AAOS

The AJRR is a crucial component of the American Academy of Orthopaedic Surgeons' (AAOS) Registry Program, which aims to enhance orthopaedic care by collecting, analyzing, and reporting actionable data. As the world’s largest national repository for hip and knee joint replacement data, the AJRR supports medical professionals with vital insights for improved patient care.

In conclusion, the growth showcased in the AJRR’s 2025 Annual Report signifies a leap toward enhanced patient safety and satisfaction in joint replacement surgeries. Through ongoing collaboration and technological advancements, the AJRR continues to establish itself as a leading authority in orthopaedic care.
