Mr Hanna is a fellowship-trained consultant orthopaedic surgeon with a specialist interest in hip and knee disorders. His NHS practice is based at the Royal London Hospital, one of the busiest major trauma centres in Europe, where he treats severely injured patients and those with complex hip and knee problems in a tertiary environment. His clinical interests include primary and complex primary joint replacements for degenerative conditions (arthritis), revision (re-do) joint replacement surgery for failure or infection, arthroscopic (keyhole) knee surgery for cartilage and ligament sports injuries, and the surgical management of lower limb trauma and fractures.

Mr Hanna’s orthopaedic training was on the Royal National Orthopaedic Hospital (RNOH) training programme during which he had excellent exposure to the full spectrum of hip and knee disorders and their reconstructive treatments including joint preservation techniques, arthroscopic (keyhole) surgery and joint replacement surgery. Following completion of registrar training, he undertook two advanced sub-speciality fellowships focusing exclusively on hip and knee surgery; the first was for a year at the University of Western Ontario in Canada, and the second was for a year at the Royal London Hospital, Barts Health NHS Trust. He also has fellowship experience from visiting a number of centres of excellence for hip and knee surgery and sports injuries in Europe including CUF Descobertas Hospital (Lisbon, Portugal), Vall d’Hebron Hospital (Barcelona, Spain) and the Rizzoli Orthopaedic Institute (Bologna, Italy).

In addition to his busy clinical commitments, Mr Hanna is an honorary senior clinical lecturer at Queen Mary University of London, where he is actively involved in research, teaching, and training. His research endeavours to date have centred primarily around hip and knee reconstruction. His main interests include the assessment of outcomes following hip and knee surgery, and evaluating the behaviour of different bearing surfaces and materials used in total hip and knee replacements. He has presented and published widely on key aspects of hip and knee surgery, and continues to conduct research looking at implant design, performance, wear patterns and outcomes of total hip and knee replacements.
