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.
One of the goals of Hospital for Special Surgery (HSS) is to advance the science of orthopedic surgery, rheumatology, and related disciplines for the benefit of patients. Physicians at HSS may collaborate with outside companies for education, research and medical advances. HSS supports this collaboration in order to foster medical breakthroughs; however HSS also believes that these collaborations must be disclosed.
As part of the disclosure process, this website lists physician collaborations with outside companies if payments were received during the prior year, or if the HSS physician currently receives payment. The disclosures are provided by information provided by the physician and other sources and are updated regularly. Further information may be available on individual company websites.
As of February 27, 2014, Dr. Hannafin reported no financial interest relationships with healthcare industry.
By disclosing the collaborations of HSS physicians with industry on this website, HSS and its physicians make this information available to their patients and the public, thus creating a transparent environment for those who are interested in this information. Further, HSS’ Conflicts of Interest Policy does not permit physicians to collect royalties on products developed by him/her that are used on patients at HSS.
