Northwestern Center for Orthopedics was formed by the merger of two world-renowned orthopedic groups (Medical Associates of Chicago and University Orthopaedic Surgeons) in 1995. The practice dates back to 1912 and has always been located in downtown Chicago. It is affiliated with Northwestern Memorial Hospital, Ann & Robert Lurie Children’s Hospital, Presence Saint Joseph’s Hospital and River North Same-Day Surgery Center.

Today, the practice has two premier orthopedic surgeons: John A. Hefferon, MD, and Proctor R. Anderson, MD. Dr. Hefferon and Dr. Anderson met while attending Northwestern University Medical School and began practicing medicine together in 1977.

Proctor R. Anderson, MD, specializes in joint repair and has been a leading Chicago surgeon for many years. He has a special interest in treating pregnant women through the use of physical therapy, particularly women who have recently delivered and suffer with shoulder, knee, elbow and low back pain.

Dr. Anderson is also a valued board member on one of Illinois’ largest insurance companies, an assistant professor at Northwestern University in the Department of Bone and Joint Surgery and practices on staff at Northwestern Memorial Hospital and Ann & Robert Lurie Children’s Hospital. In addition, he is a partner at River North Same-Day Surgery Center. 

John A. Hefferon, MD, specializes in total joint replacement as well as repair. He is the chief physician for the National Basketball Association, WNBA and National Football League. Since 2015, he has served as the chief physician for the USA Basketball Team in Crete.
