Revision Knee Replacement Q&A

What is revision knee replacement?

Revision knee replacement surgery relieves pain and restores function to your knee by removing damaged components of your prosthesis. For the best outcome, Dr. Kavanaugh and his team only use the highest quality devices by Arthrex®, Zimmer Biomet, and LimaCorporate Orthopaedic to perform revision knee replacements.

Who needs revision knee replacement surgery?

The largest joint in the human body, your knee connects your femur (thigh bone), tibia (shin bone), and fibula (outer shin bone). During your initial surgery, Dr. Kavanaugh may replace any of these elements to restore function and improve your mobility.

Although these artificial devices are designed to last permanently, injury to your knee can irreparably damage them. This can occur due to:

Fractures

A fracture, or bone break, may damage the part of your bone that secures your implant in place. Fractures can occur from a sudden injury, repeated stress from weight or exercise, or osteoporosis. This progressive condition causes porous, brittle bones that are vulnerable to breaks.

Stiffness 

One of the most common causes of stiffness after knee replacement surgery is a buildup of scar tissue. Manipulating or removing this tissue may be necessary to restore proper motion in your knee.

Instability

Injury to the ligaments that support your knee can cause instability. If you frequently feel like your knee is about to give out while standing or walking, revision surgery may be your best option.

Loosening

When your implant isn’t secured, it can move out of place and cause additional damage. Wear-and-tear of your implant, from high-impact exercise or excess weight, can shift and loosen your prosthesis.

What happens during revision knee replacement surgery?

How Dr. Kavanaugh performs revision knee replacement surgery depends on the portions of your prosthesis that need replacement. A total knee replacement may take longer to complete than a partial procedure.

When you arrive for surgery, Dr. Kavanaugh and his team administer general anesthesia or a local anesthetic to numb your knee. Next, Dr. Kavanaugh accesses your knee through the original incision to replace the damaged components. He may also remove additional tissue or cartilage if you have an infection. 

Revision knee replacement surgery is more complex than the initial procedure, so it may take longer. You may also experience a longer recovery time. Combining revision knee replacement surgery with a comprehensive physical therapy and rehabilitation plan can help support your recovery for better knee function.
