Current Research and Scholarly 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 currently the President of the American Academy of Orthopaedic Surgeons and has served on numerous AAOS committees, including the Council on Education. Previously, he was chair of the American Joint Replacement Registry Board of Directors (AJRR), and on the board of directors for the Knee Society, the Hip Society, the Western Orthopaedic Association, and the American Association of Hip and Knee Surgeons (AAHKS). Dr. Maloney is a past president of the Hip Society. He has been a Visiting Professor to numerous universities and institutions throughout the United States and Asia.
