Joint Replacement Surgeons of Indiana

Joint Replacement Surgeons of Indiana (JRSI), primarily known as the Center for Hip & Knee Surgery at Franciscan Health Mooresville, is a distinguished orthopedic surgical practice and clinical research institution based in Indiana. Founded in 1986 by Dr. Merrill Ritter, the group has gained international recognition for its pioneering work in total hip and knee arthroplasty, specifically in the areas of cementless knee replacements and long-term implant longevity studies. JRSI maintains a robust research foundation that has published over 200 peer-reviewed articles, contributing significantly to the advancement of orthopedic surgical techniques and outcomes. While the practice was fully integrated into the Franciscan Health system in 2010, its legacy continues through its high-volume clinical operations and its history as a top-ranked destination for complex joint reconstructions. Recently, many of its senior surgeons transitioned to form the Indiana Joint Replacement Institute (IJRI) to lead further innovations in value-based and outpatient musculoskeletal care.
