William J. Maloney, M.D., is a professor of Orthopaedic Surgery at Stanford University School of Medicine and Lucile Packard Children's Hospital. He primary practices at the Joint Replacement Center in Redwood City, CA. His current clinical focus is in Orthopaedic Surgery, Primary and Total Hip and Knew Replacement, Revision Total Hip and Knee Replacement, Evaluation of Failed Joint Replacement, and Unicompartmental Knee Replacement. Dr. Maloney is Board Certified in Orthopaedic Surgery by the American Board of Orthopaedic Surgery. Prior to Stanford, Dr. Maloney joined the faculty of Washington University, St. Louis as Associate Professor of Orthopedic Surgery and Head of Joint Replacement Surgery at Barnes-Jewish Hospitals in 1996. In 2000, he was promoted and selected for an endowed chair as the Charles and Joanne Knight Professor of Orthopaedic Surgery. Dr. Maloney is nationally and internationally recognized for his contributions to the improved understanding of the causes of failure of surgical joint replacement. He is known for having 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. Dr. Maloney received his B.A. from Stanford University in 1979 and his M.D. from Columbia in 1983. He subsequently completed residency in Orthopedic Surgery at Stanford, followed by a fellowship in Hip Reconstructive Surgery at the Massachusetts General Hospital.
