MAKOplasty® partial knee resurfacing

MAKOplasty® Partial Knee Resurfacing

MAKOplasty® partial knee resurfacing is a minimally invasive procedure for those suffering with painful early to mid-stage osteoarthritis of the knee. It is performed using the surgeon-controlled RIO® robotic arm system and offers more accurate resurfacing of the diseased portion of the knee, saving as much of the original knee as possible.

As a partial knee surgery, MAKOplasty can be performed on either the medial (inside) compartment, patellofemoral (top) compartment, or the lateral (outside) portion of the knee. It can also be performed as a bicompartmental procedure on both the medial and patellofemoral portions of the knee.

In many cases, patients are permitted to walk soon after surgery, drive a car within two weeks and return to normal daily activities shortly thereafter.

The use of this highly advanced robotic arm technology can:

Enable surgeons to accurately resurface the arthritic portion of the knee and preserve healthy tissue and bone

Facilitate optimal implant positioning to result in a more natural feeling knee following surgery

Result in a more rapid recovery and shorter hospital stay when compared to traditional total knee replacement surgery

Promote a rapid relief from pain and return to daily activities

How does MAKOplasty® Work?

Before surgery, a CT scan is taken of the patient's knee, and a 3D model created using the RIO system's software. From this model, a pre-surgical plan is developed for the positioning of implants based on that patient's unique anatomy.

To ensure implants are optimally positioned and that the soft tissues of the knee are balanced for a good surgical outcome, surgeons can test and fine tune the plan before surgery by moving the leg through different ranges of motion. The RIO provides measurements and visualization, and the surgeon adjusts the plan as needed.












Once the surgical plan is finalized, it is programmed into the RIO, which creates a safety zone for bone removal. While the surgeon guides the robotic arm and is in control of it at all times, the RIO ensures that bone removal stays with the safety zone of the surgical plan, providing auditory, visual and tactile feedback, stopping the robotic arm if necessary before bone can be removed outside the planned area. Once the bone preparation is complete, the implants are placed in the knee.

As a knee arthroplasty procedure, MAKOplasty® is typically covered by Medicare- approved and private health insurers.
