Mako™ Robotic-Arm Assisted Surgery at Mercy

The most advanced technology for less invasive and accurate partial knee and total hip replacement surgery

Surgeon operating MakoThis advanced system is a surgeon-controlled robotic arm system that enables accurate alignment and placement of implants. And it’s available in Cedar Rapids only at Mercy.

Each patient is unique, and can experience joint pain for different reasons. It’s important to talk with your physician about the reason for your hip pain so you can understand the treatment options available to you. Pain from arthritis and joint degeneration can be constant or come and go, occur with movement or after a period of rest, or be located in one spot or many parts of the body. It is common for patients to try medication and other conservative treatments to treat their hip or knee pain. If you haven’t experienced adequate relief with those treatment options, you may be a candidate for treatment using the Mako Robotic-Arm Assisted system, which may provide you with relief from your hip pain.

Robotic-Arm Assisted

It’s important to understand that the surgery is performed by an orthopaedic surgeon, who guides the surgeon-controlled robotic-arm during the surgery to position the implant in the knee joint. The Mako Robotic-Arm does not perform surgery, make decisions on its own, or move in any way without the surgeon guiding the robotic-arm. The Mako System also allows your surgeon to make adjustments to your plan during surgery as needed.

How it Works

Also see videos in the drop down menus below for animations of the procedures.

Mako Robotic-Arm Assisted Technology provides you with a personalized surgical plan based on your unique anatomy. First, a CT scan of the knee or hip joint is taken. This CT scan is uploaded into the Mako System software, where a 3D model of your knee or hip will be created. This 3D model will be used to pre-plan and assist your surgeon in performing your partial knee or total hip replacement.

In the operating room, your surgeon follows the personalized surgical plan while preparing the bone for the implant. The Mako system guides your surgeon within the pre-defined area and helps prevent the surgeon from moving outside the planned boundaries. This helps to provide more accurate placement and alignment of your implant.

Partial Knee Replacement with Mako™

Knee planning imagesMako Partial Knee Replacement 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.

Total Hip Replacement with Mako™

Mako hip surgeryDuring Mako Total Hip Replacement surgery, the Mako system provides images of the patient’s joint and their specific “biomechanical” information 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 shape the socket, and then implant the cup at the correct depth and location. The surgeon then implants the femoral implant.  The Mako procedure offers the confidence of more accurate cup placement and accurate leg length restoration.
