About Dr. Wright


Orthopaedic Biomechanics and Biomaterials

Dr. Wright’s research interests are in the design of orthopedic devices with an emphasis on the biomechanical performance of total joint replacements. Special areas of interest are the mechanics of the bone-implant system and wear and tribocorrosion of bearing surfaces and modular connections. He applies implant retrieval analysis integrated with stress analyses and laboratory experiments in these efforts. Other areas of interest include applying his expertise in joint mechanics to integrated experimental-computational approaches aimed at understanding joint stability including collaboration on a novel, noninvasive mouse model for studying the onset and progression of osteoarthritis.

Dr. Wright joined the Hospital for Special Surgery in 1976 and the Cornell University Medical College in 1978. He is a recipient of honors for excellence in research from the Hip Society and the Knee Society and earned a Kappa Delta Award from the American Academy of Orthopaedic Surgeons. A past Whitaker Fellow and a past recipient of a Research Career Development Award from NIH, Dr. Wright served as president of the Orthopaedic Research Society in 1992. He is a former consulting editor for research of the Journal of Bone and Joint Surgery and was co-editor of the Journal of Orthopaedic Research from 1996 to 2014. Dr. Wright received a Director's Special Citation from the U.S. Food and Drug Administration for his work on a forum of academic, industry and agency representatives striving to improve the regulatory process for orthopedic devices.  In 2013, he was awarded the Alfred Shands Award from the Orthopedic Research Society in recognition of a professional lifetime of outstanding contributions to orthopedic research.

Industry Relationships

Industry Relationships

One of the goals of HSS is to advance the science of orthopedic surgery, rheumatology, and related disciplines for the benefit of patients. Research staff 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 Research staff collaborations with outside companies if the Research staff member received any payment during the prior year or expects to receive any payment in the next year. The disclosures are based on information provided by the Research staff and other sources and are updated regularly. Current ownership interests and leadership positions are also listed. Further information may be available on individual company websites.

Below are the healthcare industry relationships reported by Dr. Wright as of April 27, 2020.

  • Agelity Biomechanics - Receives royalties
  • Imperial College London - Advisory board member
  • Rensselaer Polytechnic Institute - Advisory board member

By disclosing the collaborations of HSS Research staff with industry on this website, HSS and its Research staff make this information available to patients and the public, thus creating a transparent environment for those who are interested in this information. Further, the HSS Conflicts of Interest Policy does not permit payment of royalties on products developed by him/her that are used on patients at HSS.

Feel free to ask the Research staff member about their relationship(s).
