RUSH FOUNDATION HOSPITAL ORTHOPAEDIC SURGERY PROGRAM IS REGION’S FIRST TO OFFER HIP AND PARTIAL KNEE PROCEDURES PERFORMED WITH NEW, HIGHLY-ADVANCED ROBOTICS EQUIPMENT

MERIDIAN, MISSISSIPPI . . . Rush Foundation Hospital is the first  in the region to offer  MAKOplasty®  Partial Knee Replacement and MAKOplasty® Total Hip Replacement procedures, performed using the RIO®  Robotic Arm Interactive Orthopedic System and the Navio® Surgical System for Partial Knee Replacement Surgery.

About the MAKOplasty RIO®

The MAKOplasty RIO® is a surgeon-controlled robotic arm system that enables accurate alignment and placement of implants.

“Accuracy is key in planning and performing both partial knee and total hip procedures,” said Dr. David Pomierski, Orthopaedic Surgeon at Rush who performed the first MAKOplasty ® hip replacement in early August.   “For a good outcome you need to align and position the implants just right.  RIO enables surgeons to personalize partial knee and total hip arthroplasties to achieve optimal results.  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.  Other benefits to the patient may include greater longevity of the implant, reduced risk for relocation, decreased post-operative pain and shorter hospital stays,” said Dr. Pomierski

“Here’s how MAKOplasty Hip works:  The RIO system provides a patient-specific 3-D image of the patient’s hip based on a pre-operative CT scan. Using the 3-D model, the surgeon can then plan the optimal size and position of hip implant components. An implant consists of a cup and liner placed in the acetabulum or the socket of the pelvis, and a femoral component with a femoral head and stem. The position of these components is critical for proper biomechanical reconstruction of the hip,” added Pomierski.

During surgery, RIO provides visualization of the joint and biomechanical data to guide the bone preparation and implant positioning to match the pre-surgical plan. First the surgeon prepares the femoral bone for the implant, and subsequently measures the femoral component’s position with the RIO. Next the surgeon uses the robotic arm to accurately ream and shape the acetabulum, and then implant the cup at the correct depth and orientation. Finally the surgeon implants the femoral implant and RIO provides summary data to confirm the hip implants are aligned according to plan and leg length.

MAKOplasty RIO 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,” said Dr. Pomierski.  “MAKOplasty RIO allows us to treat patients with knee osteoarthritis at earlier stages and with greater precision.  Because it is less invasive and preserves more of the patient’s natural knee, the goal is for patients to have relief from their pain, gain back their knee motion, and return to their daily activities,” Dr. Pomierski added.  Dr. Pomierski also noted that Makoplasty RIO total knee replacement capability is anticipated in 2016.

About the Navio ™ Surgical System

The Navio™ Surgical System features proprietary robotic-assisted technology that integrates handheld intelligent instruments.  Rush Foundation Hospital is the State’s first hospital to debut the new Navio™ technology.  The Navio™ technology for partial knee replacements utilizes an advanced CT-free intra-operative registration, planning and navigation platform to assist the surgeon in building patient-specific surgical plans. The Navio™ robotic-controlled hand piece assists the surgeon in preparing the bone with the precision of robotics in a hand-held, freehand sculpting technique.

According to Dr. Gus (Sonny) Rush, Orthopaedic Surgeon at Rush, and the first surgeon in the State to use the new Navio™ equipment, “The Navio™ unicondylar and patellofemoral knee replacement software applications guide the surgeon in creating implant plans that localize components and balance soft-tissue. The technology translates that information into a virtual surgical plan that removes the need for standard mechanical cutting guides and jigs. The handheld instrumentation uses multiple control modes to help the surgeon very precisely prepare the bone for implantation.”  Dr. Rush also stated, “Potential benefits to the patient are many.  By making partial knee replacements a more accessible option through enabling very precise and predictable results, the patients who qualify for partial knee replacement have available a surgical procedure that is generally associated with smaller incisions, less scaring, a shorter hospital stay (or an outpatient procedure in some cases), and quicker recovery when compared with the total knee replacement alternative.

“Our orthopaedic surgeons, Dr. Irvin Martin, Dr. David Pomierski, Dr. Sonny Rush and Dr. Jimmy Watson are skilled and dedicated surgeons who are outstanding advocates for embracing technology and practices that improve patient care. It is exciting for everyone in our organization to have the opportunity to bring this advanced robotic technology to our State and our region in the hospital’s centennial year. 

The best news of all is for our patients - our orthopaedic surgeons are providing patients in our region who qualify as candidates for partial knee replacement with the latest technology, equipment and training so that they can have the robotic surgery here in Meridian rather than having to travel out of town for this procedure.  These new surgical tools in the hands of our skilled orthopaedic surgeons are helping keep the Rush traditions of excellence and innovation a part of this generation’s legacy,” said Larkin Kennedy, Vice President of Rush Health Systems and Administrator of Rush Foundation Hospital.
