Demand for Better Knee Replacement
Robotic-assisted Total Knee Replacement
The technology offers a new surgical option for patients with chronic knee pain due to osteoarthritis who require total knee replacement. It allows for increased accuracy of implant placement, helps implants last longer, and can reduce the patient’s recovery time.
The key to the procedure is the system’s ability to precisely replicate the surfaces of each individual patient’s damaged knee joint in the computer software without the need for preoperative CT or MRI scans. The surgeon is able to plan the size, position and orientation of the implant before making any bone cuts. Once the planning is complete, the robotic cutting guide is attached to the patient’s knee allowing the surgeon to customize each individual cut to precisely match the patient’s specific anatomy insuring the best possible placement of the implants.
The Praxim Computer Assisted Navigation System featuring Apex Robotic Technology (ART) is the only system of its kind currently available to perform total knee replacements. With ART the patient does not require expensive preoperative CT scans or MRI like other robotic systems for partial knee replacement. Although other navigation systems on the market allow surgeons to see in millimeters and single degrees, this technology allows them to adjust to single millimeters and degrees during surgery.
