Clin Asst Prof Moo Ing How

Clinical Assistant Professor Moo Ing How is a Consultant with the Department of Orthopaedic Surgery and Director of the Hip and Knee Service at Changi General Hospital (CGH). He specialises in minimally invasive and robotic-assisted hip and knee replacement surgery, including partial and total knee arthroplasty, as well as complex revision hip and knee reconstruction. His clinical specialty also encompasses joint preservation surgery, knee osteotomies, sports injuries, and trauma surgeries, including hip fractures and peri-prosthetic fracture fixation. He also performs knee ligament reconstruction, meniscal preservation, and cartilage restoration procedures.

In 2024, Dr Moo was awarded the AO Reconstruction Arthroplasty Fellowship and completed advanced fellowship training in Primary and Revision Hip and Knee Arthroplasty at Orthopädische Chirurgie München (OCM) Clinic in Munich, Germany. He subsequently pursued a second fellowship at the South West London Elective Orthopaedic Centre (SWLEOC) in the United Kingdom, gaining comprehensive training under internationally renowned surgeons. He has also undertaken visiting surgeon programmes at leading centres in the United States, South Korea, Japan, and China, further refining his expertise in robotic-assisted surgery and minimally invasive techniques.

Dr Moo received specialised training in the anterior-based muscle-sparing (ABMS) approach to hip replacement in the United States and utilises muscle-sparing kinematic alignment techniques in knee replacement surgery to optimise patient outcomes. He is the pioneer and lead for Enhanced Recovery After Surgery (ERAS) protocols in hip and knee arthroplasty at CGH thatimproves perioperative outcomes and accelerates patient recovery.

In addition to clinical practice, Dr Moo is actively involved in research, undergraduate and postgraduate education, and regional orthopaedic training programmes. He is regularly invited as faculty and speaker at orthopaedic meetings and courses in Singapore and internationally.
