Dr. Johnson is West Michigan’s only Mako Certified Physician for this advanced robotic-arm assisted partial and complete knee replacement.
Mako Knee Replacement
Knee replacement is a fairly common yet specialized surgical procedure in which a diseased or damaged joint is replaced with an artificial joint called an implant.

Made of metal alloys and high grade plastics (to better match the function of bone and cartilage, respectively), the knee implant is designed to move much like a healthy human joint. Knee replacement techniques and instrumentation have undergone numerous improvements, leading to the use of smaller incisions. Such improvements may result in less trauma to soft tissue.

If you know of someone who had a knee replaced even 5 years ago, the surgical procedure used today is likely to be quite different . . with better outcomes.

Dr. Johnson is the only orthopedic surgeon certified on the Mako Robotic-arm Assisted Surgery Technology. Mako is the latest advancement in compete and partial knee replacement surgery.

Your knee replacement begins with a CT scan of your knee joint used to generate a 3D virtual model of your unique anatomy. This virtual model is loaded into the Mako System software, where Dr. Johnson refines the data to better suit your specific anatomy. The result is your personalized pre-operative plan.

Robot Assist Knee Surgery

In the operating room, Dr. Johnson uses the Mako System to assist in performing your surgery, guided by the robotic-arm within the pre-defined area. The Mako System assures the knee is prepared according the planned boundaries defined in your personalized pre-operative plan. Mako Technology has demonstrated accurate placement of implants with soft tissue protection to the ligaments around the knee.

Partial Knee Replacement

If the osteoarthritis in your knee is limited to a single area, you may only need a partial knee replacement.

Your knee is divided into three compartments: the medial compartment (the inside part of the knee), the lateral compartment (the outside part), and the patellofemoral compartment (the front of the knee between the kneecap and thighbone).

With a partial knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee is left untouched.

The advantages of partial knee replacement over total knee replacement include:

  • Quicker recovery
  • Less pain after surgery
  • Less blood loss
  • May allow the knee to bend better
