Consultant Orthopaedic Surgeon and Aviation Medicine Specialist

Specialty Interest in Arthroscopic Joint and Ligament Reconstruction Surgery, Knee and Hip Replacement and Orthopaedic Trauma.

Dr Lai attended medical school at the National University of Singapore and thereafter completed a 6-year residency in Aviation Medicine with the Republic of Singapore Air Force (RSAF), where he became the first Singaporean to be awarded the prestigious Stewart Memorial Prize in 2002 for graduating top of his Diploma in Aviation Medicine course in London. During his time as a flight surgeon in the RSAF, he commanded a medical squadron, deployed to East Timor on a United Nations peace keeping mission and flew in various fighter jets and attack helicopters.

Upon commencing orthopaedic specialist training in 2006, Dr Lai rotated and worked in Singapore’s biggest restructured hospitals and accrued much experience learning from local orthopaedic experts. In 2012, he completed his training after obtaining his Fellowship degree from the Royal College of Surgeons of Edinburgh, and was granted full registration as an orthopaedic specialist with the Singapore Medical Council.

In 2013, he joined the National University Hospital (NUH) and spent a significant amount of time overseas attending fellowships in the region (refer below) whilst establishing his orthopaedic practice. This culminated in a full-time Orthopaedic Knee Arthroscopy, Arthroplasty and Trauma fellowship in 2014 with Drs Myles Coolican, David Parker and Brett Fritsch at the Sydney Orthopaedic Research Institute in Royal North Shore Hospital.

During Dr Lai’s time as an Orthopaedic Consultant in the Sports and Hip/Knee Divisions in NUH, his surgical interests and repertoire included computer-navigated partial/total knee and hip joint replacement, minimally invasive, arthroscopic/key-hole ligament reconstruction, including double-bundle ACLs,  as well as the latest techniques in cartilage resurfacing and regeneration.

Dr Lai has presented on the podium of various international orthopaedic meetings, given numerous talks to the public and fellow health care providers, and participated as a faculty in the Post-graduate Orthopaedic Residency Training in NUH. Dr Lai is a full member of the Singapore Orthopaedic Association and has contributed as a co-chairman of the Scientific Committee for its Annual Scientific Meeting.

Dr Lai has been an avid sportsman since young. He has donned school and university colours for swimming, athletics, volleyball, badminton, table-tennis, hockey, soccer and basketball. However, his true passion is in Rugby, a sport which he earned more than 10 caps playing for Singapore in International Test matches. Being a national rugby player has shaped Dr Lai’s ethos and approach to achieving excellence, and this experience allows his to connect with elite athletes and treat them at a level that is unparalleled.

Dr Lai strongly believes in giving back, and he currently volunteers as the Medical Director on the board of the Singapore Rugby Union. He continues to enjoy rugby every Sunday, albeit the non-contact form, and takes part regularly in overseas International Touch Rugby tournaments. His continuing participation in competitive sports provides him with the latest practical sports medicine knowledge which complements his clinical experience of treating sportsmen of different backgrounds.

Dr Lai is multilingual; he is conversant in English, Mandarin, Cantonese, Hokkien, Bahasa and is able to speak some German.
