Revision Total Knee Replacement

What Is A Revision Total Knee Replacement?

A revision of a total knee replacement means that all or part of your inserts needs to be revised as problems or wear over time can cause internal issues with your knee. Knee replacements swap the whole joint with man-made parts, which you’ll have for the rest of your life. As these man-made parts see regular use there is often wear that occurs to these parts.  Plastic inserts may shift or release particles into the knee joint which can decay bone over time and become unstable. Our specialists at Greater Phoenix Orthopedics in Scottsdale, AZ will help you with surgery.

Revision Knee Diagnosis

The knee experts at Greater Phoenix Orthopedics will put you through a thorough physical evaluation, along with diagnostic tests such as an MRI or X-ray to determine the need for revision knee replacement. These are performed to see if there is any loosening or a change in the position of the knee components and help us understand why the knee has failed.

Your body will let you know if you’re experiencing an implant that was poorly inserted or the wrong size. Common symptoms of a failed knee replacement include pain, swelling, stiffness and a loss of range of motion in the area, even well after the procedure. You can expect a quicker recovery versus traditional methods with most patients reporting 2-3 weeks post-op before they can get back to their normal routine.

Revision Total Knee Procedure

Following Anesthesia, we begin the procedure which typically takes between 2-3 hours. We follow the original incision and expose your knee joint to examine the soft tissue and look for signs of infection. We will assess the components of the knee to determine which parts need to be revised. Original implants will be removed and we’ll proceed with preparing the bone surfaces for the revision implant, adding metal augments or blocks if significant bone loss has occurred. Lastly, we will insert the new implant and repair any surrounding tissue that may be damaged. A final test of the joint motion is conducted before closing your knee up and preparing you for recovery. All while utilizing MAKO robotic technology.
