Stryker’s Mako system enables the surgeon to complete a patient specific pre-surgical plan, assessing bone preparation areas and customized implant positioning using a CT scan of the patient’s own knee. During the procedure, the system creates a three-dimensional, virtual view of the patient’s bone surface and correlates the image to the pre-programmed surgical plan. As the surgeon uses the robotic arm, its tactile, auditory and visual feedback limits the bone preparation to the diseased areas and provides for real time adjustments and more optimal implant positioning and placement for each individual patient.
