Total Knee Replacement

The Joint Replacement Institute uses Mako Robotic-Arm Assisted Technology and all our orthopedic surgeons are Mako-certified. They offer you deep experience and a record of superior outcomes in robotically-assisted partial knee replacement.

Mako Robotic-Arm Total Knee Joint Replacement Surgery

The largest joint in the body, the knee is central to nearly every routine activity. Knee pain from arthritis and joint degeneration can be constant or come and go, occur with movement or after a period of rest. It is common for patients to try medication and other conservative treatments to treat their knee pain. If you haven’t experienced adequate relief with those treatment options, you may be a candidate for total knee replacement, which may provide you with relief from your knee pain.

With over a decade of clinical history, Triathlon knee replacements are different than traditional knee replacements because they are designed to work with the body to promote natural-like circular motion.

This is due to the single radius design of the knee implant. Single radius means that as your knee flexes, the radius is the same, similar to a circle, potentially requiring less effort from your quadriceps muscle. Since the thigh muscle (the quadriceps) is attached to your knee, it is unavoidably involved in the surgery. Therefore, the quadriceps muscle can become a source of discomfort or pain during your recovery period. The quadriceps muscle plays an important role in your ability to move your legs so it also has a major impact on your recovery and how quickly you can get back to your activities.

What is Mako Robotic-Arm Assisted Surgery Technology?

Mako combines the highly developed technology of an interactive 3-D visualization system and the RIO robotic arm, providing your surgeon with the consistent pinpoint accuracy necessary to repair the worn out bone and position the implant at the optimal angle. The surgical precision of the Mako system enhances mobility and implant longevity.

What is the Mako Robotic-Arm Assisted Surgery Process?

First, a CT scan of the diseased knee joint is taken and uploaded into the Mako System software, where an interactive 3D model of your knee is created. The model is used to pre-plan and assist your surgeon in performing your total knee replacement. In the operating room, your surgeon follows your personalized surgical plan while preparing the bone for the implant. The surgeon guides the robotic arm to remove diseased bone and cartilage within the pre-defined area, and the Mako System helps the surgeon stay within the planned boundaries that were defined when the personalized pre-operative plan was created. The Mako System also allows your surgeon to make adjustments to your plan during surgery as needed.

It’s important to understand that the surgery is performed by an orthopedic surgeon, who guides the robotic-arm during the surgery to position the implant in the knee joint. The robotic-arm does not perform surgery, make decisions on its own, or move without the surgeon guiding the robotic-arm.

After surgery, your surgeon, nurses and physical therapists will set goals with you to get you back on the move. They will closely monitor your condition and progress. Your surgeon may review a post-operative x-ray of your new knee with you.

Benefits of Robotic-Arm Assisted Total Knee Replacement Surgery?

  • Smaller incision
  • Minimally invasive procedure creating less scarring
  • Less implant wear and loosening
  • More rapid recovery with a short hospital day (in most cases only 2 days)
  • More natural feeling in your new knee since there is only a 1 millimeter difference between the implant location and the original location of your own bone
  • In most cases, patients can walk soon after surgery and drive a car within the first few weeks
