The focus of our metallic biomaterials research is to characterize and engineer the biological and electrochemical interactions at the surface of metallic orthopedic implants. Metals are widely utilized for orthopedic implants applications. The metals must be mechanically strong and biocompatible to perform well within the human body. This research seeks to understand the material science and electrochemical factors that influence the biological response to metallic implants. We evaluate corrosion mechanisms of traditional orthopaedic metals (titanium, stainless steel, colbalt-chromium-molybdenum) as well as new generation biodegradeable metals (magnesium alloys) within clinically relevant conditions and in turn how corrosion influences the biological response. We also study how controlling the electrochemical properties of these metals can be utilized to enhance the desired biological response (tissue integration) while mitigating deleterious biological interactions (infection or osteolysis).
The focus of our applied biomechanics research is to develop and implement novel test methods for the mechanical evaluation of orthopedic and sports medicine devices and procedures.This research seeks to answer practical questions about surgical techniques and implant performance derived from clinical experiences and challenges. The results can provide additional insight and confidence about clinical decision-making knowing which technique or implant has proven superior biomechanical performance in controlled testing in the laboratory. Additionally, the outcomes can directly inform engineers about the optimal implant design and performance criteria.
