Partial 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.

Partial Knee Replacement Surgery

The largest joint in the body, the knee is central to nearly every routine activity. Partial knee replacement is a treatment option for people with early to mid-stage osteoarthritis that has not yet impacted their entire knee. Only the diseased portion of the knee is replaced, sparing healthy bone and ligaments.

The joint is formed by the ends of three bones, the lower end of the thigh bone, the upper end of the shin bone, and the knee cap. Since partial knee replacement surgery replaces only the damaged area of your knee, you may have an implant inserted in any of the following areas:


Medial (inside)


Lateral (outside)

Patellofemoral (top)


Bicompartmental

What is Mako Robotic-Arm Assisted Surgery Technology?

Mako combines the highly developed technology of an interactive 3-D visualization system and the 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 part of the 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 partial knee replacement surgery.

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.


Step 1. Knee CT Scan


Step 2. Partial Knee Personalized Planning

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 partial knee with you.

Benefits of Robotic-Arm Assisted Partial Knee Replacement Surgery

  • Small incision creating less scarring
  • Minimally invasive procedure – Many preformed on an outpatient basis
  • Spares healthy bone (allowing a patient to keep up to 72-percent more bone than with a “total knee” replacement procedure) and surrounding tissue.
  • Improves mobility and pain relief, since the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) are not severed during knee resurfacing
  • 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
  • Less implant wear and loosening
  • Requires minimal hospitalization and recuperation
  • More rapid recovery means a faster return to daily activities
