What is the difference between robotic-assisted and computer-navigated knee replacement?

Both computer-navigated and robotic-assisted knee replacement use technology to help the surgeon plan implant position and improve surgical accuracy, but they assist the surgeon in slightly different ways.

Computer navigation generally uses sensors, tracking devices, and specialised software to provide information about the position and alignment of the knee. The surgeon views this information on a screen and uses it as a guide while making bone cuts and positioning the implant. Robotic-assisted surgery also uses computer-based planning and tracking, but depending on the system, it adds a robotic arm or controlled surgical instrument. The surgeon operates the equipment while the system helps keep bone preparation within the planned boundaries. The robot does not independently perform the surgery.

Both technologies aim to improve precision, but their exact capabilities vary between platforms. Neither replaces the surgeon’s judgement or experience. At ASIC Clinic, the choice of technology depends on the patient’s knee anatomy, type of replacement, clinical needs, and the system considered appropriate by Dr. Atul Mishra.
