Otherwise known as MAKOplasty, it is a surgical procedure for partial knee or total hip arthroplasty using a RIO Robotic Arm Interactive Orthopedic System developed by MAKO Surgical Corp. RIO is cleared by the FDA for use in surgical knee and hip procedures, in which the use of stereotactic surgery may be appropriate, and where reference to rigid anatomical bony structures can be identified relative to a CT-based model of anatomy.
MAKOplasty is used to enable surgeons to plan partial knee or total hip replacement procedures by using three-dimensional computer imaging based on a CT scan. This allows them to determine optimal implant size, position, and alignment for each individual patient, and to map out accurately the areas of bone they want to remove. During surgery, the robotic arm system provides visual, auditory, and tactile control to help assure that surgeons cut away only the bone planned to be resected prior to surgery. The procedure is said to take the guesswork out of surgery, resulting in accurate and reproducible results.
