I am actively involved in research into hip and knee surgery. I am particularly interested in the outcomes of hip and knee replacement prostheses and surgical techniques, as well as examining the results of our world-first multi-disciplinary regional revision arthroplasty network.
This research enables me to stay up to date, and also helps me to ensure that I can offer you the best possible outcomes from your surgery.
I have presented my work nationally and internationally, and published my research in leading orthopaedic journals. I have summarised these below, and a full list can be found here.
