Dr Leon Foo graduated from the National University of Singapore in 1999 and obtained his post-graduate degrees, namely Membership of the Royal College of Surgeons of Edinburgh in 2004, Master of Medicine in Orthopaedic Surgery in 2004 and Fellowship of the Royal College of Surgeons of Edinburgh in Orthopaedic Surgery in 2008.

In 2008 Dr Foo was awarded the Singapore Government Ministry of Health Training Scholarship to pursue his fellowship training in the dual sub-specialities of Orthopaedic Oncology, Cartilage Regeneration & Joint Reconstruction at Muenster University Hospital in Germany. This was followed by a further clinical attachment at the Mayo Clinic (Rochester, Minnesota) in the United States of America.

Dr Foo is one of a handful of fellowship-trained Orthopaedic Oncologists in Singapore. As the surgical member in the multi-disciplinary oncology team looking after tumour patients, Dr Foo’s contribution lies with his expertise and experience in tumour tissue removal, as well as the subsequent reconstructive surgery. This includes limb preserving surgery for both bone and soft tissue tumours and reconstruction using autografts, allografts and/or endoprosthetic implants. His guiding philosophy with bone and soft tissue tumour treatment is not only of curative tumour removal but also of appropriate functional reconstructive procedures that allow patients to return to as full and as active a life as possible post-operatively.

Orthopaedic Oncology aside, Dr Foo is also fellowship-trained in Cartilage Regeneration and Joint Reconstruction surgeries. His clinical expertise is often called upon in the treatment of hip, knee, foot, ankle and shoulder problems arising from a variety of causes, be it degenerative (age-related), inflammatory, trauma or sports-related injuries. His surgical repertoire includes the latest technologies in cartilage resurfacing and regeneration, as well as joint replacement, including minimally invasive, arthroscopic, computer navigation, robotic and customized implants.

A three-time recipient of the “Service with a Heart Award” during his practice at the Singapore General Hospital, compassionate and holistic patient-centric care remains the most important tenet of Dr Foo’s clinical practice


Upon his return to Singapore in 2010, Dr Foo was made a Consultant with the Department of Orthopaedic Surgery at the Singapore General Hospital. He was concurrently appointed as Visiting Consultant to the National Cancer Centre Singapore, Kandang Kerbau Women & Children’s Hospital, as well as Tan Tock Seng Hospital. 

Clinical work aside, Dr Foo was appointed as Adjunct Assistant Professor to the Yong Loo Lin School of Medicine, National University of Singapore, as well as Clinical Tutor with the Duke-NUS Graduate Medical School. He is an Advanced Trauma Life Support Instructor and is actively involved as Physician Faculty for both the Orthopaedic Surgery and Family Medicine Residency Programmes. Dr Foo continues to be regularly called upon as Teaching Faculty for both local, as well as international courses and conferences. He also remains an expert Reviewer for several PubMed indexed international medical journals including the Journal of Arthroplasty.

Medical research is a cornerstone of Dr Foo’s work. He is an avid researcher, having published several papers in international, peer reviewed orthopaedic journals. In recognition of his clinical expertise and research contribution, he has been invited and continues to be an expert Reviewer for several PubMed indexed international medical journals including the Journal of Arthroplasty, Singapore Medical Journal, and Annals of the Academy of Medicine of Singapore.
