American Joint Replacement Registry

What American Joint Replacement Registry does

The American Joint Replacement Registry (AJRR) is a national, multi-stakeholder clinical registry focused on hip and knee arthroplasty procedures, operating as a program within the American Academy of Orthopaedic Surgeons (AAOS) Registry Program. Founded circa 2013 and headquartered in Rosemont, Illinois, AJRR collects, validates, and analyzes real-world procedure data contributed by participating surgeons, hospitals, and healthcare systems. As of its 12th Annual Report released in 2025, the registry holds over 4.4 million procedure records, reflecting an 8.8% year-over-year increase in data capture.

The registry's core technology infrastructure centers on the RegistryInsights® platform, which provides participants with benchmarking dashboards, performance reports, and analytics, and the PRO Portal, a patient-reported outcome survey collection system offered at no additional cost to participants. Data quality is reinforced through formal collaborations with Blue Cross Blue Shield Association and Aetna, which align the registry with payer-side data validation standards. The registry also extends internationally, with contributors outside the United States represented in the 2025 dataset.

AJRR operates as a nonprofit, with revenue generated through institutional participation fees and industry partner data partnerships via a dedicated Corporate Engagement Program. It serves surgeons, healthcare administrators, researchers, and medical device and pharmaceutical companies, with primary segments being surgeons/orthopaedic clinicians and healthcare administrators. Pricing is not publicly disclosed; participants engage directly with the registry team for enrollment. The organization runs with a lean headcount of 1-10 employees as a program within AAOS, and there have been no disclosed funding rounds, acquisitions, or leadership changes.

Others

• Definitive Healthcare: Commercial healthcare commercial intelligence and RWD provider used by medtech and life sciences companies. Tangentially comparable to AJRR as an alternative data source for orthopaedic market and procedure analytics.
• American Academy of Orthopaedic Surgeons (AAOS): Parent professional association under which AJRR operates. Relevant as the governing, funding, and distribution ecosystem that defines AJRR's strategic and operational constraints.
• National Quality Registry Network (NQRN): A community of registry stakeholders advancing best practices in clinical registries. Comparable to AJRR as a peer in the registry ecosystem, but functions as an enabling/coordination body rather than a competing data repository.

Direct peers

• Registry Partners: A commercial clinical registry services and analytics provider supporting hospital and society-led registries across therapeutic areas. Comparable to AJRR as a registry operations and data abstraction/analytics peer serving healthcare organizations.
• American College of Surgeons National Cancer Database (NCDB / ACS): ACS operates large national clinical registries (NCDB, NSQIP) with similar multi-stakeholder governance, hospital participation, and benchmarking analytics. Conceptually analogous to AJRR as a physician-society-led national outcomes registry.
• Swedish Knee Arthroplasty Register (SKAR): Sweden's national knee arthroplasty registry, among the oldest and most-cited orthopaedic registries worldwide. Directly comparable to AJRR in procedure focus (knee) and real-world outcomes research orientation.
• National Joint Registry (NJR): The UK National Joint Registry collects hip, knee, ankle, elbow, and shoulder arthroplasty data at a national scale. It is the closest international analogue to AJRR in scope, methodology, and stakeholder model (clinicians, hospitals, regulators, industry).

Emerging players

• ArborMetrix: A clinical analytics platform purpose-built for specialty society registries and quality reporting. Comparable to AJRR on the analytics/benchmarking layer that RegistryInsights® provides to participants.

Broad incumbents

• IQVIA Real World Evidence: Global commercial RWE and RWD platform with deep orthopaedic and device post-market surveillance datasets. Comparable to AJRR as an alternative source of orthopaedic real-world evidence for industry partners and researchers.
