Research Description

Orthopaedic Biomechanics and Biomaterials

Dr. Wright’s research interests are in the design of orthopedic devices with an emphasis on the wear of polyethylene total joint components. He is also focusing on the performance of bone implant systems and the analysis of retrieved components and problems with fixation as well as the mechanical properties of bone tissue.

Among Dr. Wright's current projects are an integrated approach to understanding knee component wear combining observations on retrieved components, wear experiments on a knee joint simulator, and a numerical simulation of the simulator. The goal is to provide a direct link between the wear damage mechanisms and the stress and strain state of the material.

Also under investigation are a study of cortical bone response to load as function of magnitude, frequency and duration, and a study of trabecular bone remodeling under the influence of load and growth factors using an animal model.

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 is currently editor of the Journal of Orthopaedic Research. Recently, 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.
