Dr. Leo A. Whiteside, an internationally known orthopaedic surgeon-inventor and educator from St. Louis, Missouri, is recognized as one of the world’s foremost authorities on osteointegration technology in total knee and hip arthroplasty. In the early 1980s he pioneered one of the first successful cementless total knee systems along with the first intramedullary alignment instrumentation system for knee surgery. He has designed three total hip systems, two total knee systems, a unicondylar knee system, and several surgical instruments. In the past decade he has dedicated much of his research effort to ligament balancing techniques in knee arthroplasty. After collecting and comparing extensive cadaveric laboratory and surgical-clinical data, he has developed protocols for balancing ligaments in primary and revision knees. As director of the Missouri Bone and Joint Center and its affiliated research foundation, Dr. Whiteside has published approximately 200 peer-reviewed journal articles and book chapters. He also serves on numerous orthopaedic committees and journal review boards.

M. E. Roy, PhD, whose expertise is in biomechanics, biomaterials science, and bone and mineral research, directs the ongoing laboratory research projects for the Missouri Bone and Joint Research Foundation. By combining basic materials science research with analysis of retrieved implants, Dr. Roy’s goal is to better understand the tribology of wear couples used in joint replacement, minimizing wear and the need for revision surgery. Current projects include impact testing of ceramic femoral components for TKA; measuring the amount of metal worn from cobalt-chromium alloy femoral components in a knee wear simulator; and the examination and testing of retrieved and artificially aged zirconia oxide and zirconia-toughened alumina femoral heads, to determine how material composition helps or inhibits resistance to aging and roughening in clinical use.

Paul Meyer specializes in field videography, and has extensive experience in videotaping orthopaedic surgery for live broadcast. He coordinates the archival and retrieval system for Dr. Whiteside’s video library, and helps Dr. Whiteside prepare video segments for use in presentations to other orthopaedic surgeons at research meetings and continuing education courses.

Diane Morton, MS, a medical writer and editor, prepares and coordinates the written research materials for medical journals and textbooks, and the coursebooks for surgeon continuing education courses.
She coordinates the submission of research studies for presentation at annual research meetings, and creates the scientific exhibits and posters for display. She also prepares health and orthopaedic-related information for patients of the Missouri Bone and Joint Center, and for community publications.
