Precision in Total Knee Replacement: A Technical Note on the VELYS Robotic-Assisted Tibial-Femoral Approach

The VELYS robotic-assisted system (DePuy Synthes, Warsaw, IN, USA) in total knee replacement (TKR) enables precise bone registration and resection, reducing manual errors and minimizing soft tissue injury compared to conventional methods. This method will provide a more accurate implant position with a better postoperative range of motion (ROM). This technical note describes the steps in performing robotic-assisted TKR using the VELYS with a tibial-femoral approach. In more detail, this article will discuss surgical exposure and creating bone checkpoints and landmark acquisitions, tibial-femoral resection, and implant placement. Despite the existing benefits, the long-term advantages still need further investigation.
