Q-What is newer technology for knee replacement surgery..???????????? Ans - According to Dr LAVESH Agrawal Orthopedic Surgeon (MS ORTHOPEDIC GOLD MEDALLIST) Computer navigated TKR Computer navigated TKR is performed using an advanced system with a highly specialized software, infrared camera and trackers. During surgery, trackers are temporarily attached to the patient’s knee bones which transmit data to the infrared camera. This data is processed by the computer to provide real time 3D information about the patient’s knee joint and leg alignment. The surgeon uses this information to plan bone cuts, adjust soft tissue tension, customize implant position and insert the artificial knee joint accurately. Precise implant positioning is likely to reduce joint wear, and improve the lifespan of the artificial joint. This technology also forms an important part of robotic TKR. The reported benefits of computer navigated TKR include better alignment, improved patient satisfaction, superior clinical outcomes, lesser blood loss and lower blood transfusion rates. It also results in lesser post-operative inflammation which may reduce pain and swelling aiding early mobilization and recovery. The world’s first computer navigated TKR was performed in France two decades ago. The technology has undergone extensive upgrades since then. The current generation of systems are comprehensively validated for accuracy, have enhanced functionality and are more user-friendly. As a result, its use is growing in India and the rest of the world.
