Our Total Joint Center Team

The Total Joint Center is proud to have some of the most well-respected and skilled physicians in the field of orthopedics. The physicians and staff not only work to give the best care, but also the the best possible recovery.
Program Director, Total Joint Center

John A. Froehlich, MD is the program director of the Total Joint Center at The Miriam Hospital. He is a specialist in the areas of adult reconstructive surgery and sports medicine, and he operates on patients of all ages suffering from a variety of shoulder, hip and knee ailments. Many of these procedures are done arthroscopically, which often means less pain, shorter rehabilitation and a quicker return to work. 

Included among the reconstructive procedures are: shoulder surgeries for rotator cuff disease, instability and impingement; knee surgeries for tissue repair; corrective procedures for arthritis, including joint replacement; and hip surgery including hip replacements. He is also involved in research on improving cartilage properties and the quality of joint replacements. 

Froehlich is a member of the American Academy of Orthopaedic Surgeons, American College of Surgeons and the American Board of Orthopaedic Surgeons. He is also a clinical assistant professor of orthopaedics at The Warren Alpert Medical School of Brown University. He is on staff at both Rhode Island Hospital and The Miriam Hospital.

Director of Research, Total Joint Center

Roy Aaron, MD is professor of orthopedics and professor of molecular pharmacology, physiology and biotechnology at Brown University. He completed his orthopedic training in the Harvard Combined Orthopedic Program and a fellowship in joint replacement surgery at the Robert Brigham Hospital. Aaron completed two research fellowships at the National Institutes of Health (NIH), one studying surgical physiology and one in basic cartilage biochemistry. He founded both the orthopedic laboratory and the joint replacement service at The Warren Alpert Medical School of Brown University.

Aaron’s clinical interests focus on joint diseases, particularly on osteoarthritis and avascular necrosis, and conservative therapies for joint preservation. Recent clinical investigations have concerned the role of knee arthroscopy, contrast-enhanced MRI for early diagnosis of osteoarthritis, and the prevalence of coagulopathies in both osteoarthritis and avascular necrosis. In the laboratory, he has been investigating the contributions of circulatory pathology to the initiation and progression of osteoarthritis. 

Aaron has served on 35 national panels, including ten NIH study sections, and committees of the Arthritis Foundation, American Academy of Orthopedic Surgeons and Orthopedic Research Society. He has authored over 100 scientific and clinical papers and three books. Several years ago, he received a Lifetime Achievement Award from the New England Arthritis Foundation.
