Roy K. Aaron, MD

Director of Research, Total Joint Center

Roy Aaron, MD is conducting research to investigate osteoarthritic arterial blood vessel wall mechanics, assessing compliance and pulse wave velocity, using ultrasound. His clinical interests have focused on joint diseases, particularly on osteoarthritis and avascular necrosis and their relationships to vascular biology. Clinical investigations have concerned the role of knee arthroscopy, contrast-enhanced MRI of bone circulation in osteoarthritis, and the prevalence of coagulopathies in both osteoarthritis and avascular necrosis.

He maintains a joint replacement registry for outcomes research that currently has data on over 7,000 joint replacements. In the laboratory, he has been investigating the contributions of circulatory pathology to the initiation and progression of osteoarthritis. He has also focused on osteoporosis and metabolic bone diseases and has organized the department’s osteoporosis and bone health program.

Dr. Aaron is professor of orthopedics at The Warren Alpert Medical School of Brown University. He completed an internship in medicine at Montefiore Hospital, NY and a residency in Orthopedic Surgery at the Harvard Combined Orthopedic Program including a fellowship in joint replacement surgery at Brigham and Women's Hospital. Dr. Aaron completed five years at the National Institutes of Health studying surgical physiology and critical care, and basic cartilage biochemistry. He founded both the orthopedic laboratory and the joint replacement service at The Warren Alpert Medical School of Brown University. He is currently chair of the Brown medical faculty executive committee.

Dr. Aaron has served on over 45 national panels, including 20 National Institutes of Health (NIH) and U.S Department of Defense (DoD) study sections, and on committees of the Arthritis Foundation, American Academy of Orthopedic Surgeons, and Orthopedic Research Society. He has authored over 135 scientific and clinical papers and chapters, and five books.

Dr. Aaron is a recipient of the 2023 Foundation’s Physician Excellence Award. Several years ago, he received a lifetime achievement award from the New England Arthritis Foundation.
