Mako Robot for Total Hip and Total Knee replacement and Partial Knee Surgery

The addition of the MAKO Robot demonstrates United Regional’s commitment to precision medicine and expands our regional leadership in robotic orthopedic surgery.

How robot-assisted joint replacement works

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 by your surgeon to create your personalized pre-operative plan.

Total Hip and Total Knee Replacement

During an operation, the surgeon guides the Mako robotic-arm, which will limit their movements, as they prepare the bone for the implant, to within the boundaries set by the pre-plan. This means only the diseased bone is removed. The robot will then help with positioning the implant based on the patient’s anatomy.

Partial Knee Replacement

Partial knee replacements are designed to relieve the pain caused by osteoarthritis (OA). By targeting the part of the knee damaged by OA, a surgeon can replace the diseased bone while helping to spare the healthy areas and ligaments surrounding it.

The stability and precision of orthopedic surgery robotics means that the task of knee resurfacing is made much easier. By limiting the unnecessary removal of healthy tissue and bone, and better positioning implants – trauma and pain is reduced.

After Surgery

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.

Orthopedic Navigation System

The Stryker Navigation System for total hip and total knee replacement surgeries offers a technology that can assist in more accurate implant alignment and proper ligament balancing, which are essential for stability, durability and sufficient range of motion.

Navigated total knee and total hip replacement is an extremely successful way to treat qualifying patients with severe joint pain. The surgical navigation technology greatly enhances the ability to restore range of motion and overall function, and allows patients to return to normal activity more quickly.


The Stryker Navigation System uses an infrared camera and instruments along with unique tracking software to continually monitor the position and alignment of the implant components in relation to the patient’s anatomy. The computer analyzes and displays data on a computer monitor which show the angles, lines and measurements needed to more accurately align the prosthetic hip or knee.

One benefit of the Navigation System is that it eliminates the need for pre-operative X-rays or CT scans. Experience shows that the system may lead to shorter hospital stays, fewer post-operative complications, and improved joint stability.
