MAKO Surgical Corp. announced that it will launch the next generation of its robotic arm system and implants used for MAKOplasty partial knee resurfacing, at the American Academy of Orthopaedic Surgeons (AAOS) 2009 Annual Meeting in Las Vegas. The RIO Robotic Arm Interactive Orthopedic System and the RESTORIS MCK MultiCompartmental Knee System make bone and tissue sparing MAKOplasty partial knee resurfacing available to a larger population of patients. Previously, it was only possible to perform this precision resurfacing surgery on the medial (inner) portion of the knee. Now it can be performed on the medial, patellofemoral (top) or both components of the knee, offering a large and growing population of patients with early to mid-stage osteoarthritis (OA) of the knee a less invasive treatment option than total knee replacement. “The field of medical robotics is coming of age, and MAKO is committed to leading the way in orthopedic surgery,” said Dr. Maurice R. Ferré, President, Chief Executive Officer and Chairman of the MAKO Board of Directors. “The advancement of our technology with RIO and RESTORIS MCK allows a greater number of patients with osteoarthritis to benefit from the precision and improved outcomes of MAKOplasty.” MAKO’s robotic arm system is the first FDA-cleared robotic arm system for orthopedic surgery. It provides patient-specific, three-dimensional modeling for pre-surgical planning. As surgeons use the robotic arm to resurface the knee for placement of the implants, RIO provides realtime inter-operative visual, tactile and auditory feedback, enabling a high level of precision and optimal positioning of the implants. MAKOplasty provides the potential for improved surgical outcomes, with a less invasive partial knee resurfacing procedure that spares healthy bone and tissue, preserves ligaments and allows for a more rapid recovery and a more natural feeling knee.
