ROSA Knee Robotic Assistant

The success of your knee replacement surgery is closely linked to the fit and function of the new knee implant⁵. The ROSA Knee system provides your surgeon with a 3D model of your knee so they can more accurately plan every step of your procedure. By knowing what to expect, your surgeon can predetermine how they’ll best fit your implant to give you the best outcome based on your unique anatomy. Your surgeon can choose between three clinically proven Knee implant systems based on your needs and their experience^{6, 7}.

During surgery, the ROSA Knee system combines precise sensors, live data and a robotic arm with your surgeon’s skill and experience, to help your surgeon precisely place your implant and assess the knee with the implant in place. This allows your surgeon to make final precise adjustments before finishing the surgery resulting in an implant position more accurately placed than by traditional methods1. It’s a bit like having a second expert in the room.

Your surgeon and nurses will guide you through a detailed recovery plan and follow up appointments. They will closely monitor you during your recovery to make sure you get back to doing the things you love as quickly as possible.

If you’ve been recommended by your doctor for knee replacement surgery and are interested in ROSA, then contact our enquiry team to find out more or book an appointment. 

When you’re considering robotic knee replacement surgery, it’s only natural you’ll have some questions. 

If you need any further information, our friendly enquiry team are on hand to help.
