She is an Attending Orthopedic Surgeon and Director of Orthopedic Research at Hospital for Special Surgery and has published and lectured extensively on tendon and ligament healing. She is a Professor in the Department of Orthopedic Surgery at Weill Cornell Medical College.

Dr. Hannafin was a USOC physician for the 2004 Olympic Games in Athens, Greece and the 2003 Pan American Games in the Dominican Republic. She is currently the Head Team Physician for the WNBA New York Liberty and a Team Physician for the United States Rowing Team.  She was an event physician at the 1996 Atlanta Olympic Games (rowing); and the New York City Marathon. Dr. Hannafin was a team physician for the WUSA New York Power from 2000-2003 and an Assistant Team Physician to the New York Mets from 1992-1996. She has been team physician to the U.S. Rowing Team since 1994 and is a member of the FISA Medical Commission. Dr. Hannafin was a member of the silver medalist lightweight double at the 1984 World Rowing Championships and a three-time gold medalist at the U.S. National Rowing Championships. She is currently the Vice President of the Board of Trustees of the National Rowing Foundation.

Dr. Hannafin is the Vice President of the American Orthopaedic Society for Sports Medicine and will serve as President from 2013-2014. She has served as Secretary of the AOSSM board, Chair of the Enduring Education and Research Committees and has served on numerous AOSSM committees. She has been a member of the Board of the OREF (Orthopaedic Research and Education Foundation) from 2006-2012. She has published over 70 papers in peer-reviewed journals and has written 20 book chapters. She is also the co-author of the book Say Goodbye to Knee Pain. Dr. Hannafin has been repeatedly honored as one of The Best Doctors in America.

Dr. Hannafin was the first Clinician-Scientist at the Hospital for Special Surgery and maintains an active research program in the area of ligament physiology. Her section of the Laboratory for Tissue Engineering, Regeneration and Research is focused on the study of soft tissue response to injury, stress deprivation and mechanical loading in a variety of tissues including the anterior cruciate ligament and shoulder capsule. Cell culture, and molecular techniques are used to study cellular response to physical and chemical alteration in the environment with a specific focus on mechanotransduction pathways involved in these responses. Dr. Hannafin has received NIH RO1 funding and various foundation funding in support of this research area. She has served as a full member of the SBSR NIH Study Section and as an ad hoc member of a number of other Study Sections.
