Welcome to my Website!
 Life is Movement – Movement is Life! While this is true for everyone, it is especially true for athletes. My aim is to provide the highest quality patient care, improve mobility, enhance the quality of life for all my patients, and to advance the science of orthopedic surgery through research and education. I specialize in sports related issues and injuries of the lower extremities. Our approach is ‘Integrative’, drawing upon multiple medical and holistic disciplines, providing you with a comprehensive solution and state of the art options for your treatment and recovery.
My practice is based in New York's Hospital for Special Surgery (www.hss.edu).
The Hospital for Special Surgery is the oldest orthopedic hospital in the United
States, presently ranked as the #1 Orthopedic Hospital in the U.S.A.
Our interactive multimedia option is highly informative and designed to help you
understand very specifically – the exact nature of your injury and situation.
Please bear in mind that the information on our website is provided to support
and reinforce the advice you receive from your own doctors. It is not intended
to replace discussions with your doctor. That being said, I hope you find my
website both informative and helpful.
Should you have any further questions, please do not hesitate to contact me ...

November 21, 2011 - Registration has begun for the 2012 International Congress on Cartilage Repair of the Ankle Joint, which will be held in Dublin, Ireland on March 9-10, 2012. The Congress is organized by the European Society for Sports Traumatology Knee Surgery and Arthroscopy (ESSKA) Ankle and Foot Associates in collaboration with Hospital for Special Surgery. The Congress is chaired by Dr. John G. Kennedy, Prof. C. Niek van Dijk and Dr. Richard D. Ferkel. This meeting represents the first of its kind for cartilage repair of the ankle and demonstrates a willingness to foster international collaboration among leaders in the field. We are pleased to have a world-renowned faculty and special guest speakers committed to attend from 12 different countries on 4 continents. Please visit the Congress website for more information.
June 30, 2011 - Dr. Kennedy's abstract titled "Autologous Osteochondral Transplantation of the Talus Partially Restores Contact Mechanics of the Ankle Joint" was presented at the 3rd Joint Meeting of the British Orthopaedic Research Society and Bone Research Society on Wednesday, June 29, 2011 in Cambridge, United Kingdom. This biomechanical study, performed at the Hospital for Special Surgery, found that the OATS procedure restored regional contact mechanics of the ankle joint. While slight alterations in local contact mechanics were observed in the study, further investigation is warranted to determine whether or not these differences are clinically significant. This study was recently accepted to the American Journal of Sports Medicine, and will be published in 2011.
