Singapore orthopaedic surgeon Glen Liau’s team has developed a surgical guide tool to improve the safety and precision of robot-assisted total knee replacement procedures in Singapore.

• Guidance tool: A patented jig guides tracker pins through a single incision with accuracy to within 1mm/1° for robot-assisted knee arthroplasty.
• Clinical use: The tool has been successfully used in more than 200 patients here since 2023 and validated in a 102-patient study published in Arthroplasty in 2025.
• Complication reduction: Laboratory and clinical results show lower fracture risk versus conventional pin placement and integration with an AI algorithm aims to shorten surgery time.
