Dr Ruy da Assunção


Dr da Assunção grew up in Johannesburg, South Africa and qualified as a doctor from the University of the Witwatersrand in 1997. He moved from South Africa to the UK in 1998 where he completed his intern training and began training in surgery. Thanks to some enthusiastic mentors, he developed an early affinity for Trauma and Orthopaedics during basic surgical training. After working in Orthopaedics and Trauma, Emergency Medicine, General Surgery and Cardiothoracic surgery, he was awarded MRCS by the Royal College of Surgeons of England in 2001 and began Specialist Orthopaedic Training in 2003.


Dr da Assunção trained in the Wessex Deanery in Southern England and received comprehensive training in all aspects of Orthopaedic and Trauma Surgery in surgical units across the South of England. This culminated in the award of FRCS (Tr&Orth) in 2008. In 2008, he undertook the AO / OTA Trauma Fellowship at the world-renowned Harbourview Medical Centre in Seattle, USA to learn about complex trauma surgery. In 2009 he travelled to Sydney where he undertook the Lower Limb Reconstruction and Arthroplasty Fellowship with Professor Warwick Bruce, where he was trained in the intricacies of complex hip, knee, reconstruction and revision surgery.

In Sydney during 2009 he met his future wife, who agreed to accompany him back to England the next year. In 2010 Dr da Assunção undertook the Perth Trauma Fellowship at the Royal Perth Hospital where he gained further experience in the management of major and complex Orthopaedic trauma. For 18 months over 2010 and 2011, Dr da Assunção was a hip and knee Fellow at the Nuffield Orthopaedic Centre in Oxford, UK, an internationally recognised centre of excellence. He trained with Professor David Murray, Mr Christopher Dodd, Mr Adrian Taylor and other thought leaders in the field to become proficient in the management of all aspects of lower limb reconstruction. This included expertise in partial knee replacement and complex primary and revision surgery of the hip and knee, including the management of musculoskeletal infection.

Dr da Assunção was appointed as a Consultant in Orthopaedic and Trauma Surgery at Western Sussex Hospitals NHS Trust (now University Hospitals Sussex) at the end of 2011. He established a public practice in lower limb surgery and orthopaedic trauma at Worthing Hospital, Worthing and St Richard’s Hospital, Chichester and developed an interest in complex arthroplasty, peri-articular and orthogeriatric trauma and knee preservation surgery. His public practice was complemented with a private practice at Goring Hall Hospital in Worthing and The Nuffield Hospital in Brighton.

After the birth of his daughters in 2017 and 2019, he and his family made the difficult decision to leave the UK to re-unite the children with their extended family in Australia and they relocated in early 2020, initially to Perth and then Sydney. Dr da Assunção was awarded Fellowship of the Royal Australasian College of Surgeons in 2023 and established Revolution Orthopaedics, a practice intended to provide a modern, holistic, tailored surgical service to patients with musculoskeletal problems or trauma. He also partnered with Dr Brian Martin and Dr Manish Gupta to create The Hills Orthopaedics, a comprehensive orthopaedic surgical solution for the people of Sydney and beyond.

Dr da Assunção lives in the Hills district of Sydney with his wife and daughters. He enjoys fishing, cooking, cinema and remains a die-hard Alfa Romeo enthusiast.
