John G. Kennedy, MD

Dr. John Kennedy graduated from Royal College of Surgeons in 1989 and has since practiced in both Ireland & the U.S. He specializes in osteochondral injuries, Achilles tendon injuries, ankle instability, and ligament reconstruction and has a primary interest in lower limb surgery, particularly sports-related injuries.

Dr. Kennedy is currently the clinical director of the running clinic at Hospital for Special Surgery. His interest in sports medicine of the lower limb is generated by a long personal history in sports, where he competed at National and International levels in track, rugby, fencing, and water skiing. As part of his Fellowship year, Dr. Kennedy was involved as an assistant team physician to Boston College Football in 1994-95. Since then, he has been involved in the treatment of both recreational athletes as well as elite athletes from the New York Giants, New York Metro Stars, Manhattan Rugby, the National Basketball Players Association, the National Basketball Referees Association, and the National Hockey League Players Association.

Dr. Kennedy's involvement in all aspects of lower limb sports injuries has led him to publish articles on soccer injuries, running injuries, cycling injuries, ballet injuries, and ankle instability following sports injuries. He has published more than 100 peer-reviewed articles. Read more about Dr. Kennedy on his personal websites, www.sportsmedicinenewyork.com; www.osteochondraldefects.com.
