Highlights of the 2025 American Joint Replacement Registry Annual Report

Abstract

The 2025 American Joint Replacement Registry Annual Report includes 4.6 million hip and knee arthroplasty procedures, with 4,434,668 validated cases, representing a 20% increase from the prior report. Registry participation continues to expand, with contributions from over 5000 surgeons and 1200 institutions, including an increasing submission of patient-reported outcome measures. A key methodological change includes the adoption of Kaplan–Meier survivorship analysis, allowing improved assessment of time-dependent revision risk. Ongoing efforts to improve data completeness and registry infrastructure continue to support registry-driven research.
