American Joint Replacement Registry

The American Joint Replacement Registry (AJRR) is the largest national clinical data registry for total joint replacement in the United States. It focuses on collecting and reporting data on hip and knee replacement procedures to improve patient outcomes and safety. By providing orthopaedic surgeons and healthcare institutions with comprehensive performance reports and benchmarks, AJRR facilitates evidence-based decision-making. The registry is a cornerstone of the American Academy of Orthopaedic Surgeons (AAOS) Registry Program, serving as a critical resource for tracking implant performance and longitudinal patient outcomes.
