Total Knee Replacement Revision
A revision total knee replacement involves replacing all or part of the components in your knee implant due to wear, complications, or other issues that develop over time. Total knee replacements resurface the joint with artificial materials designed for long-term use. However, regular wear and tear can occur, particularly in the plastic inserts, which may shift or release particles into the joint. These particles can lead to bone deterioration and joint instability. At The Joint Replacement Center of Scottsdale, our knee revision specialists are here to guide you through this complex but necessary procedure.
Diagnosis
The knee revision experts at The Joint Replacement Center of Scottsdale will use a thorough physical evaluation along with diagnostic tests such as MRI or X-ray to determine your need for revision knee surgery. These are performed to see if there is any loosening or a change in the position of the knee components and to help us understand why the knee has failed. 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.
About the 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 wound and preparing you for recovery. All of this is done utilizing MAKO robotic technology.

Frequently Asked Knee Surgery Questions.
We’re here to address your concerns and provide clarity about all aspects of hip surgery. Contact us if you have additional questions you would like answered.
Can I swim?
You can swim 2 weeks after surgery.
When can I drive?
Each patient is different and it depends on which leg was operated on but generally when:
- You are not taking narcotics during the day
- You can comfortably get in on the drivers side
- You feel you are strong enough to get from the gas to the brake quickly enough to avoid an accident
When can I golf?
Typically 6 weeks after surgery.
When can I fly?
You can fly 2 weeks after surgery, but with precautions. You are at risk for a blood clot for 3 months after surgery. If you fly during this time you should be on aspirin 81 mg twice a day or a stronger blood thinner for air travel.
Will I set off metal detectors?
Your knee will likely set off the metal detectors. Always budget extra time when visiting a location with metal detectors. If you do set off the detector, notify the TSA agent that you have a joint replacement. Airports no longer accept implant cards as proof and will still require you to undergo screening.
What activities will I be allowed to do after I am healed?
Most patients can return to all activities 3 months after surgery although full healing can take up to 1 year. However, high impact activities such as running can lead to early wear of the joint and should be avoided.
What are the extra pin holes for?
The pin sites are where Dr. Martin attaches the robotic trackers. No hardware is retained at the site.
What does the Robot do and why do I need a CT scan?
The robot provides accuracy and precision in order to improve on the results of traditional joint replacement. Dr. Martin is present at all times during the surgery and is working in conjunction with the robot. The CT scan allows Dr. Martin to create a digital 3D model of your joint to template your surgery and ensure accurate bone prep and implant position.
Returning to work after surgery?
Time off varies depending on how physically demanding your work is
- For physically demanding jobs 6 weeks
- For desk or seated jobs 2 weeks
Why are there fees for work forms?
Work forms require a significant amount of staff resources and are not reimbursed by insurance.
How many procedures has Dr. Martin performed?
Dr. Martin has successfully performed over 5000 robotic joint replacements since 2009.
Why can’t I have a handicapped placard after surgery?
Dr. Martin encourages walking as part of your recovery. You should take every opportunity to use your new joint.
What are the implants made of?
Cobalt chrome, titanium, and polyethylene plastic. Some knees have bone cement which is methyl methacrylate. If you have a nickel allergy and were provided a specialized implant it is typically made with ceramic or oxinium titanium, and polyethylene plastic.
