Clinical interests

Mr Kosuge developed his passion for Trauma & Orthopaedics as a junior doctor and pursued this by enrolling onto the North-East Thames Percival Pott Orthopaedic Training Programme. His training took him to prestigious centres including The Royal London Hospital, The Royal National Orthopaedic Hospital and Norfolk & Norwich University Hospital. He was inspired by a number of his excellent trainers to focus on the subspecialty of hip and knee joint replacements.

Following completion of specialist training in the United Kingdom, he enrolled onto and successfully completed a one-year fellowship at the Royal Adelaide Hospital in Australia under the auspices of Professor Donald Howie. This fellowship allowed Mr Kosuge to refine his skills in hip and knee joint replacements, as well as revision hip replacements. During his orthopaedic training, he was the recipient of the British Orthopaedic Association (BOA) Zimmer Adult Reconstruction Hips and Knees Fellowship in 2014, the AOTrauma Fellowship in 2013 and the Tohoku University Orthopaedic Visiting Fellowship in 2010 – and utilised his time visiting, learning and exchanging ideas with centres of excellence in Japan.
