Also known as knee arthroplasty, total knee replacement surgery may help restore balance, mobility, and strength to your knee when nonsurgical treatments don’t work.

During the procedure, a knee surgeon will remove damaged tissue and recreate the surface of the knee joint using artificial materials. These artificial materials include metal and plastic components that help your knee joint glide smoothly.

We believe a natural, customized fit to your anatomy is important. That’s why we offer the following options:

Robotic Knee Replacement Surgery

Makoplasty is an advanced, robot-assisted technology that is a less invasive and more accurate alternative to traditional surgery. The entire procedure, from preparation to implant, is customized to your unique anatomy for a more natural fit and better function.

Most patients return directly home after surgery, while some go to a rehabilitation hospital for more physical therapy. As with other joint surgeries, patients must do hourly exercises to strengthen the joint and regain mobility. Initial recovery takes about six to eight weeks, and then often continues for a full year.

If you have arthritis or another injury limited to one area of your knee, you may be a candidate for partial knee replacement surgery. During the surgery, a knee surgeon removes only the damaged portion of the knee, leaving the healthy parts untouched. Only one compartment is replaced, compared with three compartments in a full joint replacement.

It’s also a much less invasive procedure than traditional surgery, meaning you can expect a smaller incision, less blood loss, and faster recovery times.

The artificial parts used in knee replacements are designed to last for a long time. However, they can become damaged over time from natural wear and tear, a fracture, or infection to nearby tissues. When that happens, an orthopedic surgeon may remove the damaged artificial knee joint replace it with a new one in a procedure called knee revision surgery.

Your knee replacement should be as unique as you. That’s why we offer Makoplasty® technology—a 3D planning and guidance tool that gives our surgeons the ability to develop a pre-operative plan for each patient and optimize the fit of the joint replacement during the surgery itself.

From beginning to end, this advanced, robot-assisted technology allows us to perform a more accurate, less traumatic procedure compared to traditional surgery. And, it allows us to completely customize your new joint so that it feels natural and moves seamlessly.

How Robotic Knee Replacement Works

Before robotic surgery begins, your knee specialist uses a CT scan and special software to create a 3D model of your knee. This model is used to prepare a surgical plan and determine your implant’s size and position.

During the surgery, your surgeon guides the robotic-arm according to your personalized plan to prepare the patient’s knee joint. During this step, they will only remove only the diseased bone while keeping your healthy bone and tissue intact. It’s important to note that the surgeon is in complete control of the robotic-arm. The Mako robotic arm does not perform surgery or move in any way without their guidance. The surgeon can make real-time adjustments to fit, ligament tension, and soft-tissue balance.

Next, the surgeon implants the replacement knee joint called a prosthesis. Makoplasty helps to ensure the highest level of accuracy in placement which allows the joint to work more smoothly and with less wear and tear.
