Richard L. Illgen II, MD

Dr. Illgen is certified by the American Board of Orthopedic Surgery and has completed specialized training in adult reconstructive surgery (hip and knee replacement at Harvard-Massachusetts General Hospital). He currently serves as co-director of the Arthritis and Joint Replacement Program at The University of Wisconsin School of Medicine and Public Health.

Dr. Illgen is nationally and internationally regarded as an expert, thought leader, and innovator in robotic assisted hip replacement, knee replacement, and partial knee replacement surgery. Early studies have demonstrated improved outcomes after robotic-assisted surgery compared with traditional techniques (see below). Dr. Illgen has been instrumental in developing and implementing this technology in the United States, and travels across the world teaching orthopedic surgeons best practices and the latest techniques.

Dr. Illgen's practice includes primary and revision hip and knee replacements, as well as partial knee replacements (unicompartmental knees). He has particular expertise and experience regarding the care of young patients with hip and knee arthritis and offers care including joint preservation and joint replacement for this high demand group of individuals. These interests reflect a treatment philosophy that emphasizes the application of scientific analysis and innovative techniques to optimize care for patients requiring hip and knee replacement.
