Providence Medford Medical Center offering hip and knee procedures performed with highly-advanced robotic arm technology

November 01, 2015

Providence Medford Medical Center is the first in southern Oregon to offer MAKOplasty® Partial Knee Resurfacing and MAKOplasty® Total Hip Replacement procedures, performed using the RIO® Robotic Arm Interactive Orthopedic System marketed by MAKO Surgical Corp. RIO is a surgeon-controlled robotic arm system that enables accurate alignment and placement of implants.

"Robotic-assisted surgery allows for better planning and tracking as the surgery takes place," said Todd Clevenger, orthopedic surgeon with Southern Oregon Orthopedics. "MAKO allows you to map out the joints, such as a knee, electronically. Using computerized tracking technology, the sensors tell you exactly where the knee is and that information goes to the robot which allows you to remove bone precisely, down to a half of a millimeter. All of the soft tissue is still prepared in the traditional way with the surgeon cutting the skin and opening the capsule of the knee joint, but the removal of the bone, which is the trickiest part of any joint replacement, is guided by the robot. The robot has no power of its own, but does keep the surgeon from straying and removing bone he didn't plan on removing."

The RIO System features a patient-specific visualization system and proprietary tactile robotic arm technology that is integrated with intelligent surgical instruments. It assists surgeons in pre-planning and in treating each patient uniquely and with consistently reproducible procedure.

MAKOplasty Partial Knee Resurfacing is a treatment option for adults living with early to mid-stage osteoarthritis that has not yet progressed to all three compartments of the knee. It is less invasive than traditional total knee surgery. A pre-surgical plan is created based on a CT scan of the patient's own knee, and the surgeon uses the robotic arm during surgery to resurface the diseased portion of the knee, sparing healthy bone and surrounding tissue for a more natural feeling knee. An implant is then secured in the joint to allow the knee to move smoothly again.

During MAKOplasty Total Hip Replacement surgery, RIO provides visualization of the joint and biomechanical data to guide the bone preparation and implant positioning to match the pre-surgical plan. After first preparing the femur or thighbone, the surgeon uses the robotic arm to accurately ream and shape the acetabulum socket in the hip, and then implant the cup at the correct depth and orientation. The surgeon then implants the femoral implant. MAKOplasty offers the confidence of more accurate cup placement and accurate leg length restoration. "We are proud to be the first to use this innovative technology in southern Oregon," said Cindy Mayo, chief executive of Providence's Southern Oregon Service Area. "It is part of our commitment to provide our community with the best possible healthcare."
