Why Does the Need for Revision Knee Replacement Arise
Total knee replacement surgery involves replacing your natural knee joint with an artificial implant. While this surgery is highly successful, sometimes the implant can fail or wear out. If this happens, Dr. Ihekweazu can help you with a revision knee replacement surgery in Houston.
Some of the common reasons for revision knee replacement include:
Loose or Worn Implant
Over time, the implant may become loose or wear down, causing knee pain. A knee replacement revision surgery can help improve function.
Infection
An infection can develop after surgery or years later, causing severe knee pain or stiffness. In severe cases, revision surgery may be necessary.
Instability
Damaged ligaments can make the knee unstable and prevent the implant from working properly. If other treatments don’t work, revision knee replacement may be needed.
Fractures
If the bone around the implant breaks, you may need a revision procedure to repair or replace the damaged part.
Preparing for Revision Knee Replacement
Before your revision knee replacement surgery, Dr. Ihekweazu thoroughly evaluates your condition and assesses the damage to your existing implant. This involves a physical examination in addition to imaging tests, blood work and joint aspiration.
In a typical knee replacement, the damaged parts of the femur, tibia, and patella are replaced with artificial implants. However, if these implants wear out or become loose over time, you may need revision surgery.
As your revision knee replacement surgeon in Houston, Dr. Ihekweazu carefully examines your case and considers all factors.
Procedure of Knee Replacement Revision Surgery in Houston
Revision knee replacement surgery is more complex and time-consuming than a regulard knee replacement. As an experienced knee revision specialist in Houston, Dr. Ihekweazu utilizes state of the art techniques to achieve the best possible result.
Dr. Ihekweazu starts by making a cut along the same line as the previous incision (oftentimes, he will be able to remove the previous scar entirely to make the new scar look better). This will expose the knee joint, allowing him to examine the metal and plastic parts. Dr. Ihekweazu then carefully removes any loose or worn-out components, preserving as much of your natural bone as possible.
After removing the old parts, he prepares the bone surfaces for the new prosthesis. He also repairs the surrounding soft tissues and closes the incision with stitches.
Post-Surgery Care for Revision Knee Replacement
After your surgery, you’ll need to follow a revision specific recovery and rehabilitation program. This includes taking pain medication, attending physical therapy sessions, and using blood thinners to prevent blood clots. Initially, you’ll need to use an assistive device like a walker.
As your revision knee replacement surgeon in Houston, Dr. Ihekweazu and our team will provide detailed instructions for your at-home care. The recovery time varies depending on individual factors, such as the complexity of your surgery, your healing ability, activity level, and overall health. Dr. Ihekweazu and our team will be there to support you throughout the recovery process, helping you get back to your normal activities more easily.

Frequently Asked Questions
How long do most knee replacements last before revision is needed?
About seventy seven percent of total knee replacements last beyond twenty five years. Revision becomes necessary mainly when implants loosen or wear, when infection develops, or when fracture or ligament instability occurs.
What tests are required before revision knee surgery?
Evaluation includes a physical examination, X rays, blood work, and joint aspiration to rule out infection. These results tell Dr. Ihekweazu which components are failing and how to plan your Houston revision.
Will my scar look worse after revision knee surgery?
Usually not. Dr. Ihekweazu reopens along the previous incision line and can often remove the old scar entirely, which frequently leaves a cleaner appearance than after your original knee replacement.
Why do I need blood thinners after knee revision?
Longer and more complex surgery raises clot risk, so blood thinners form part of your recovery protocol alongside physical therapy, pain medication, and early walking with a walker or other assistive device.
What if my knee feels unstable but the X rays look normal?
Ligament damage or a worn plastic liner can cause instability even when images appear acceptable. Dr. Ihekweazu tests knee balance under stress and may recommend revision when bracing and therapy fail.
