Type	Nonprofit registry
Purpose	Prosthetic joint arthroplasty surveillance

American Joint Replacement Registry is a national clinical registry that aggregates data on hip and knee arthroplasty procedures performed across the United States. Established to monitor outcomes, prosthesis performance, and complication rates, the registry aims to inform Food and Drug Administration surveillance, Centers for Medicare & Medicaid Services policy, and clinical practice guidelines from societies such as the American Academy of Orthopaedic Surgeons and the American Association of Hip and Knee Surgeons. The registry operates in collaboration with state health departments, academic centers, and specialty organizations including the American Board of Orthopaedic Surgery and the American Hospital Association.

History

The registry was created amid growing attention to device safety following high-profile device failures and regulatory scrutiny involving companies like DePuy Orthopaedics, Stryker Corporation, and Zimmer Biomet. Early development involved stakeholders from the Orthopaedic Research and Education Foundation and the American Association of Orthopaedic Surgeons and received technical guidance shaped by precedent registries such as the Swedish Hip Arthroplasty Register, the National Joint Registry (England and Wales), and the Australian Orthopaedic Association National Joint Replacement Registry. Initial leadership included surgeons tied to centers at institutions like Johns Hopkins Hospital, Mayo Clinic, and Cleveland Clinic. Expansion in the 2010s paralleled initiatives by the Patient Protection and Affordable Care Act era quality measurement efforts and collaborations with the Society of Thoracic Surgeons for registry methodology exchange.

Organization and Governance

AJRR is governed by a board that includes representatives from professional organizations such as the American Academy of Orthopaedic Surgeons, the American Association of Hip and Knee Surgeons, the American Hospital Association, and consumer advocates similar to those who participate in National Quality Forum panels. Operational partners include commercial health informatics vendors and academic research partners at universities like Duke University, University of California, San Francisco, and Harvard Medical School. The registry’s governance structure reflects models used by the National Cardiovascular Data Registry and the Society of Thoracic Surgeons National Database, with committees for data science, quality measures, and surveillance. Funding sources have included grants from private foundations, partnerships with industry stakeholders such as Johnson & Johnson, and contracts with federal entities like the Agency for Healthcare Research and Quality.

Data Collection and Methodology

AJRR collects procedural, implant, provider, and outcome data using standardized elements adapted from the International Consortium of Orthopaedic Registries recommendations and the Centers for Disease Control and Prevention procedure coding frameworks. Data submission occurs via electronic health record interfaces, health information exchanges used by systems such as Epic Systems Corporation and Cerner Corporation, and manual abstraction comparable to methods from the National Surgical Quality Improvement Program. Case definitions align with Current Procedural Terminology codes and device identifiers use the Global Unique Device Identification Database schema advocated by the U.S. Food and Drug Administration. Risk adjustment and longitudinal follow-up use statistical approaches similar to those in publications from The Journal of Bone and Joint Surgery, The Lancet, and JAMA.

Key Findings and Impact

AJRR analyses have informed comparative evaluations of implant survivorship and identified variation in revision rates across hospitals and surgeons, echoing findings reported in journals like Clinical Orthopaedics and Related Research and Bone & Joint Journal. Reports influenced payer and regulator attention to device performance, contributing to advisory discussions at the Food and Drug Administration Advisory Committee meetings and policy deliberations within the Centers for Medicare & Medicaid Services. Academic studies leveraging AJRR data have been cited by researchers at institutions such as Stanford University, University of Pennsylvania, and University of Michigan, and have informed clinical guideline updates from the American Academy of Orthopaedic Surgeons and consensus statements by the International Society of Arthroplasty Registers.

Participation and Membership

Participation includes hospitals, ambulatory surgery centers, and private practices enrolled through regional collaboratives and specialty networks linked to entities like the American Hospital Association and state hospital associations. Membership models mirror those of the National Surgical Quality Improvement Program and the American College of Surgeons collaboratives, with tiers for academic centers (e.g., Mayo Clinic, Cleveland Clinic), community hospitals, and device manufacturers that contribute de-identified device data. Collaborative initiatives have included partnerships with state quality programs and professional societies such as the American Association of Hip and Knee Surgeons to expand case capture and surgeon engagement.

Privacy, Security, and Data Use Policies

AJRR implements data governance and privacy controls consistent with Health Insurance Portability and Accountability Act of 1996 requirements and uses de-identification techniques aligned with guidance from the Department of Health and Human Services and standards such as those recommended by the National Institute of Standards and Technology. Data linkage for outcomes employs probabilistic matching strategies used in registries linked to claims from Centers for Medicare & Medicaid Services and private payers like UnitedHealth Group and Aetna. Research data requests undergo committee review similar to processes at the National Institutes of Health intramural programs, and data security practices follow frameworks promoted by the Office of the National Coordinator for Health Information Technology.

Criticisms and Limitations

Critiques mirror those levied at large clinical registries, including incomplete case capture compared with mandatory national systems like the Swedish Hip Arthroplasty Register and potential reporting bias similar to issues faced by the National Surgical Quality Improvement Program. Limitations include variability in data completeness across institutions, challenges in long-term follow-up analogous to problems identified in the National Joint Registry (England and Wales), and resource burdens for small practices similar to concerns raised about participation in the American College of Surgeons National Surgical Quality Improvement Program. Observers have noted potential conflicts of interest when industry partners such as Zimmer Biomet, Stryker Corporation, or DePuy Orthopaedics provide device data, prompting calls for transparency consistent with standards from the National Academies of Sciences, Engineering, and Medicine.
