Singapore, February 12: A team at Alexandra Hospital (AH) Orthopaedic Surgery has obtained an international Patent Cooperation Treaty (PCT), which is administered by the World Intellectual Property Organization, and that protects this algorithm for robotic total knee replacement for its uniqueness, exclusivity, novelty and proprietary rights. Filed since August 2024 in over 150 member countries to seek patent protection, to-date, there are no other similar concepts or technologies found through rigorous examination and vast data searching by independent patent authorities. Singapore's patent was filed in October 2023 earlier, and had established that as a computational algorithm designed to improve the accuracy and efficiency of robotic total knee replacements (rTKR), it is one of a kind.
