Total Knee Replacement with Mako

Mako can be used for Total Knee Replacement (TKR), which is a treatment option for adults living with mid- to late-stage osteoarthritis of the knee. Mako provides you with a personalized surgical plan based on your unique anatomy. 

The Mako technology provides your surgeon with a patient-specific 3-D model to pre-plan your total knee replacement. During surgery, they guide the Mako robotic-arm based on your patient-specific plan. This allows the surgeon to remove the diseased bone, preserve healthy bone and soft tissue, and position the implant based on your anatomy.

How it works


Have a plan personalized for you 

First, a CT scan of your knee joint is taken. This CT scan is uploaded into the Mako System software, where a 3-D model of your knee is created. This 3-D model is used to pre-plan and assist your surgeon in performing your total knee replacement.

In the operating room

During surgery, your surgeon follows your personalized surgical plan while preparing the bone for the Triathlon Total Knee implant. 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.1-4 

Your surgeon then guides the robotic-arm to remove diseased bone and cartilage within the pre-defined area. The Mako System helps them stay within the planned boundaries that were defined when the personalized pre-operative plan was created. In a laboratory study, Mako Technology demonstrated accurate placement of implants to a personalized surgical plan.5

After surgery 

After surgery, your surgeon, your 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 an x-ray of your new knee replacement with you.
