Revision Hip Replacement Q&A

What is revision hip replacement surgery?

Revision hip replacement surgery aims to repair damaged portions of your hip prosthesis. While most initial hip replacement surgery cases are highly successful, your prosthetic device can become dysfunctional for many reasons. 

Dr. Kavanaugh and his team perform a comprehensive evaluation to determine what that reason is. Once they identify the source of your hip dysfunction, they can determine which component to replace and choose the best revision approach for you.

Who needs revision hip replacement surgery?

Some of the most common reasons for revision hip replacement surgery include:


When the bone around your prosthesis breaks, or fractures, your implant may no longer function as it should. Car accidents and falls are the most common reasons these fractures occur. If you fracture your hip with a prosthesis, Dr. Kavanaugh first assesses the damage to determine whether your implant is loose, broken, or surrounded by bone fragments.

Repeated dislocations

As a ball-and-socket joint, your hip is vulnerable to dislocation. If your implant repeatedly dislodges from the socket, you may need a realignment or a new prosthesis altogether.

Prosthesis loosening

Just like your natural hip, your prosthesis should fit firmly into your socket. A loosening prosthesis can lead to chronic pain and instability. While direct impact to your hip can cause loosening, the most common reason this occurs is gradual wear. High-impact exercise, excess weight, and inactivity can all cause wear-and-tear.


Infection occurs when bacteria adheres to your prosthetic hip. Most infections happen shortly after surgery, but they can develop several years after your initial procedure. Infection causes inflammation that can interfere with the bond between your artificial hip and socket.

What happens during revision hip replacement surgery?

Before revision hip replacement surgery, Dr. Kavanaugh and his team administer general anesthesia, an epidural, or a different type of anesthetic to numb your body from the waist down. Next, Dr. Kavanaugh cuts into your skin through the same incision as your initial surgery. Through this incision, he removes and replaces the damaged elements with new devices.

Since a revision hip replacement is more complex than the initial procedure, you can expect a longer surgery time, hospital stay, and recovery time. To prevent complications after surgery, it’s important to follow a comprehensive physical therapy and rehabilitation plan.

Revision hip replacement surgery is a safe, effective treatment to restore hip function if your initial procedure fails. To learn more, call the Tim Kavanaugh, MD, office nearest you, or use the online booking tool today.
