Partial Knee Replacement with Mako

Mako equipment for Tufts Medical Center in downtown Boston, MA.

Mako can be used for partial knee replacement (PKR), which is a procedure designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA) in one or two compartments of the knee. By selectively targeting the part of your knee damaged by OA, Dr. Zarin can replace the diseased part of your knee while helping to spare the healthy bone and ligaments surrounding it.

The Mako technology provides Dr. Zarin with a patient-specific 3-D model to pre-plan your partial knee replacement. During surgery,he guides the Mako robotic-arm based on your patient-specific plan. This allows him to remove only the diseased bone, preserving healthy bone and soft tissue, and assists him in positioning the implant based on your anatomy.

How it works

1 – Have a plan personalized for youA CT scan of a knee joint for Tufts Medical Center in downtown Boston, MA.

It all begins with a CT scan of your joint that is used to generate a 3D virtual model of your unique anatomy. This virtual model is loaded into the Mako system software and is used to create your personalized pre-operative plan.

In the operating room, Dr. Zarin will use Mako to assist in performing your surgery based on your personalized pre-operative plan. The Mako system also allows him to make adjustments to your plan during surgery as needed. When he prepares the bone for the implant, the Mako system guides them within the pre-defined area and helps prevent them from moving outside the planned boundaries. This helps provide more accurate placement and alignment of your implant.

3 – After surgeryAn x-ray of a partial knee for Tufts Medical Center in downtown Boston, MA.
