Scientific Focus
Current Research Interests
Dr. Maloney is nationally and internationally recognized for his contributions to the improved understanding of the causes of failure of surgical joint replacement. For example, he established a critical link between polyethylene wear debris and bony erosion, with resulting significant changes in the materials and design strategies of joint replacement surgery. More recently, he has shown that wear debris particles are coated in vivo with human proteins, such as albumin; this observation has notably improved the validity of in vitro investigation in this area. His research in the area of joint replacement has twice won awards from the Hip Society. Dr. Maloney is a member of the Central Program Committee of the American Academy of Orthopedic Surgeons, and he chairs multiple additional national committees, including the National Hip and Knee Registry Work Group of the American Academy of Orthopedic Surgeons, the Awards Committee of the Association of Bone and Joint Surgeons, the Awards and Publications Committee of the Hip Society, and the ABC Exchange Fellowship Subcommittee of the American Orthopedic Association. He has been a Visiting Professor to numerous universities and institutions throughout the United States and Asia.
