Knee osteoarthritis is a leading cause of chronic pain and disability, with limited disease modifying therapies—yet glucagon-like peptide 1 receptor agonists may reduce progression to total knee arthroplasty. In this episode of RAPM Focus, Executive Editor Anahi Perlas, MD, FRCPC, explores whether or not GLP-1 receptor agonists may reduce the risk of arthroplasty for total knee osteoarthritis with Ryan D’Souza, MD, and Jay Karri, MD. Their conversation follows the April 2026 publication of their original research paper, “Glucagon-like peptide 1 receptor agonist use and risk of arthroplasty for knee osteoarthritis: retrospective database analysis.”
