Trauma and Orthopaedic Surgeon (Hip and Knee)

Special Interests:

  • Primary, complex primary and revision (re-do) total hip replacements
  • Partial (unicompartmental) and total knee replacements (primary, complex primary and revision)
  • Bespoke (custom-made) and robotic assisted hip and knee replacements
  • Minimally invasive total hip and knee replacements
  • Arthroscopic (keyhole) knee surgery for cartilage, meniscal and soft tissue injuries
  • Cartilage regeneration and transplantation procedures
  • Knee ligament reconstruction (anterior cruciate ligament – ACL)
  • Lower limb trauma and fractures


Mr Hanna is a fellowship-trained Consultant Orthopaedic Surgeon with a specialist interest in hip and knee disorders, sports injuries, and lower limb fractures. He is practising at the leading, internationally renowned teaching Royal London Hospital.

He is a fellow of both the Royal College of Surgeons of England (FRCS) and the American College of Surgeons (FACS). His NHS practice is based at the Royal London Hospital, one of the busiest major trauma centres in Europe, and at the Barts Health Elective Orthopaedic Centre (BHOC). His clinical practice encompasses all aspects of hip and knee surgery, including primary and complex primary joint replacements, revision (re-do) surgery for failure or infection, arthroscopic (keyhole) knee surgery for cartilage and ligament injuries, and the surgical management of lower limb trauma and fractures.

In addition to his clinical commitments, Mr Hanna is an honorary senior clinical lecturer at Queen Mary University of London, where he is heavily involved in research, teaching and training. He is a member of the Faculty of Surgical Trainers (FST) at the Royal College of Surgeons of Edinburgh and is the orthopaedic education lead at the Royal London Hospital.


Mr Hanna’s training was on the prestigious Royal National Orthopaedic Hospital (RNOH) Stanmore training programme, during which he had excellent exposure to the full spectrum of hip and knee disorders and their reconstructive treatments including arthroscopic (keyhole) and joint replacement surgery. Following completion of his training, he undertook two advanced sub-speciality fellowships focusing exclusively on hip and knee surgery; the first was for a year at the world-renowned Rorabeck-Bourne Joint Replacement Institute at the University of Western Ontario in Canada, and the second was for a year at Barts Health in London. He was also awarded the EFORT Mark Paterson travelling fellowship in 2017, during which he visited centres of excellence for hip and knee surgery in Portugal (CUF Descobertas Hospital, Lisbon), Spain (Vall d’Hebron Hospital, Barcelona) and Italy (Rizzoli Orthopaedic Institute, Bologna).

Academically, Mr Hanna has more than 10 years’ experience conducting clinical research in the UK and Canada. His research endeavours 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 successfully completed a research doctorate – MD (Res) at University College London studying the biological effects of wear particles generated from total hip 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 arthroplasty. This vast research experience allows him to practice evidence-based medicine utilising the most advanced technologies and surgical techniques, and choosing the most appropriate implants/prostheses for his patients.

Mr Hanna believes that the best outcomes for patients can only be achieved when decisions are carefully considered and discussed within the framework of a multidisciplinary team. He works closely with fellow orthopaedic surgeons, anaesthetists, radiologists and physiotherapists to offer each patient a personalised and individual treatment plan.
