Robotic Knee Replacement

About Robotic Knee Replacement

MedStar Union Memorial Hospital is the first hospital in the entire state of Maryland to perform robotic total knee replacements. Now, we are performing more Makoplasty procedures than any other hospital in the state. When it comes to partial or total knee replacement, the right fit is everything. So, we offer a unique robotic knee replacement, Makoplasty, which is changing the lives of patients for the better.

• Better fit and function
• Personalized to each patient
• More accurate and less invasive

This advanced, robot-assisted technology is a less invasive and more accurate alternative to traditional surgery. The entire procedure, from preparation to implant, is customized to each patient’s unique anatomy for a more natural fit and better function.

Each patient is unique and can experience joint pain for different reasons. It’s important to talk to us about the reason for your knee 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. Most patients try medication and other conservative treatments before considering surgery. If you haven’t experienced adequate relief with those treatment options, and you are an adult living with osteoarthritis, you may be a candidate for Mako robotic knee replacement, which may provide you with relief from your knee pain.

How It Works

Mako Robotic Arm Assisted Technology provides you with a personalized surgical plan based on your unique anatomy. First, a CT scan of the diseased knee joint is taken. This CT scan is uploaded into the Mako System software, where a 3D model of your knee will be created. This 3D model will be used to pre-plan and assist your surgeon in performing your  knee 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. The precise alignment allows the new joint to work more smoothly, with less wear and tear.

It’s important to understand that the surgery is performed by an orthopedic 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.
