MAKO Surgical has announced the release of its RIO Robotic Arm Interactive Orthopedic System. On display at this week’s American Academy of Orthopaedic Surgeons annual meeting in Las Vegas, the device is designed to assist surgeons during knee resurfacing operation, a minimally invasive type of surgery thought to be useful for younger, active patients with early osteoarthritis. Since the knee resurfacing is a notoriously difficult operation to perform, the hope is that such a robot will introduce stability and precision.
From MAKO’s press release:
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 real-time 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.
