Hip replacement is a common surgical procedure. According to the Canadian Institute for Health Information, there were over 40,000 hospitalizations for hip replacements in Canada in 2010-2011. Notably, about 35% of the patients were under the age of 65. With an aging population and the increasing number of younger patients diagnosed with osteoarthritis, the demand for joint replacements will continue to grow and so will the need to improve implant longevity. In her presentation, Dr. Catelas will discuss some of the current challenges with hip replacements, considering both the material and biological aspects. She will also explain some of the approaches her research group is investigating to improve hip implant longevity through the identification and modulation of molecular mechanisms involved in hip implant failures.


Dr. Catelas received her Bachelor's Degree in Biological Engineering from the Université de Technologie de Compiègne (UTC) in France in 1995, her Master's degree from the École Polytechnique de Montréal in 1997, and her Ph.D. from McGill University in 2002, the latter two in Biomedical Engineering. After a few years in the biotechnology industry in the US, Dr. Catelas joined the Department of Mechanical Engineering at the University of Ottawa in May 2008, with a cross-appointment at the Faculty of Medicine. Dr. Catelas is an Associate Professor and holds a Canada Research Chair (Tier II) in "Bioengineering in Orthopaedics". Her research interests include the study of implant wear and corrosion, the identification and modulation of molecular mechanisms involved in the biological response to implant wear particles and metal ions, as well as bone tissue engineering. The ultimate objectives of her research are to improve implant longevity and offer new treatment options for patients suffering from bone loss.
