What is the VELYS™ Robotic-Assisted Solution?
It's not a robotic surgery itself, but rather a "surgeon's intelligent assistant."
Many people mistakenly believe that the robot will perform all the surgery itself. In fact, VELYS™ is an intelligent robotic arm controlled 100% by a skilled surgeon. The system performs:
Real-time data analysis: Evaluates tendon tightness and laxity and knee joint balance during surgery.
Precise planning: Helps surgeons position the artificial knee for personalized alignment to the millimeter.
Perimeter control: Prevents the instrument from impacting surrounding tissue, tendons, or nerves.
Why choose VELYS™ for knee surgery? The difference you can feel.
✅ No CT Scan Required (CT-Scan Free): VELYS™'s key advantage over previous robots is that it uses high-resolution cameras to capture actual bone in the operating room, reducing preparation and waiting times. Importantly, it eliminates unnecessary CT scan radiation exposure.
✅ Less Pain and Faster Recovery: With high precision, it minimizes injury to surrounding tissues, resulting in a faster recovery. Many patients are able to stand and walk weight-bearing within 24 hours after surgery (depending on individual physical condition).
✅ Natural Feel: The knee is adjusted to best fit the patient's original anatomy, ensuring post-operative comfort, freedom from discomfort, and natural movement compared to traditional surgery.
