Professor McKellop’s research areas include: musculoskeletal biomechanics, stabilization and healing of fractures; improving the durability of orthopaedic implants; developing and evaluating wear resistant bearing materials for prosthetic joints (hip, knee and spinal disc replacements), particularly crosslinked polyethylene and metal-metal bearings; through the analysis of retrieved implants, evaluating how the design and bearing material affect the long-term clinical performance; use of computer modeling (finite element analysis) to evaluate and improve the performance of many types of orthopaedic implants, particularly the nature of the bone-implant interface.
