Research Interests

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.
