Dr. Mark P. Figgie is Chief of the Surgical Arthritis Service at Hospital for Special Surgery. He is one of the leading experts in joint replacement for inflammatory arthritis, and performs more than 500 surgeries a year. His training in engineering and biomechanics has helped him become instrumental in the design of implants for elbows, knees, and hips, including the design of custom implants. As Chief of the Surgical Arthritis Service, Dr. Figgie oversees the comprehensive care of patients with systemic diseases including rheumatoid arthritis, lupus, lyme disease, and hemophilia. Taking a uniquely coordinated approach, orthopedic surgeons work closely with a team that includes a rheumatologist (the physician who oversees the non-surgical treatment of the disease), an anesthesiologist, a physical therapist, a social worker, and a biomechanical engineer.
