Navigated Assisted Total Knee Replacement

A Total Knee Replacement is considered the Gold Standard for advanced osteoarthritis of the knee. This is considered one of the most successful procedures in orthopedic medicine. We have seen wonderful outcomes with this surgery. 90% of cases have proven successful longevity and have lasted upwards of 15 years.

Easy, precise, and accurate

Have you ever experienced your vehicle when it is out of alignment—your car movement doesn’t feel right and your tires may produce uneven wear, requiring you to need a new set? Joints in the bodywork in a very similar fashion.

When patients require a total joint replacement, proper placement and alignment of the implant are critical to the implant’s overall longevity and function.  ExactechGPS® Guided Personalized Surgery combines surgeon expertise with an advanced computer system, similar to a navigation device in your car, to perform your joint replacement surgery with a goal of advanced accuracy and precision.

When it comes to knee replacement, accurate placement and alignment of the implant components are critical to the overall longevity and function of the implant. Traditionally, surgeons have used pre-operative X-rays, instrumentation and special techniques to plan the surgery and calculate the fit and positioning of the total knee implant. While this has worked well for many years, studies have shown the risk of implant failure increases substantially when the implant is outside of three degrees of alignment. ExactechGPS was developed to assist surgeons to meet their goals of precision and accuracy in total joint replacements; it has been shown to be accurate with less than one degree of variability.*


  • ExactechGPS Guided Personalized Surgery: provides Dr. Marquez with a comprehensive view (3-D model) of your unique knee joint and bone structure, which can be difficult to view during traditional knee surgery

  • Allows your surgeon to easily make adjustments to ensure accuracy and precision based on your unique anatomy

  • Can be combined with less invasive approaches that have been shown to result in less blood loss and faster recovery times

  • Combined with the Exactech knee system that has proven design, proven materials and proven performance over time

With a few simple trackers placed on the patient's bone, the system sends data on the patient's anatomical structure and joint movement to the computer. 

The computer analyzes the information it has gathered and displays it on the screen in a graphical format with calculated key measurements

The images on the screen allow Dr. Marquez to verify where to remove bone and appropriately place the implant
