Knee Revision Surgery
Total knee replacement allows patients with severe knee arthritis to lead more active lives by relieving pain and restoring function in the knee for many years.
Over time, the knee replacement implants can begin to wear or loosen, requiring a second procedure called knee revision surgery. During a knee revision procedure, the original implants are replaced with new implants.
Knee revision surgery is typically more complex than the original procedure, so it is important to choose a surgeon experienced in revision surgery. Dr. Niels Linschoten specializes in knee revision surgery, and has several years of experience with this procedure.
Total Knee Replacement
When patients have severe arthritis in the knee that limits daily activities, a total knee replacement may be recommended. During a total knee replacement, Dr. Linschoten replaces the damaged portions of the joint with metal implants. A plastic spacer is inserted between the two metal components to allow the joint to glide smoothly.
For most patients with severe knee arthritis, a total knee replacement is an effective solution, relieving pain and restoring function in the knee for many years after the procedure. However, over time the components can experience wear and tear. This may lead to instability and other complications in the knee, and the implants may need to be replaced. Knee injuries or complications after total knee replacement, such as infections, may also require another procedure.
When knee replacement implants need to be replaced with new components, the procedure is called knee revision surgery.
Candidates for Knee Revision Surgery
Implant wear and loosening is a common reason for knee revision surgery. Over time, the implants can begin to loosen from the underlying bone to which they are attached. The plastic spacer between the implants can also begin to wear down. Implant wear or loosening is common among patients who had a total knee replacement at a younger age--they “outlive” their implants.
Knee revision surgery may also be necessary for patients who injure the ligaments or fracture the bones surrounding the knee replacement. These injuries may lead to instability, requiring an additional procedure to stabilize the knee and allow it to function properly.
Complications from the initial knee replacement can also necessitate knee revision surgery. A small percentage of patients develop infections after the initial knee replacement procedure. In some cases, the implant may need to be removed and replaced so that the infection can be properly treated. Excessive scar tissue from the initial procedure can also limit range of motion, which may require a revision procedure.
Knee Revision Procedure
Knee revision surgery is generally more complex than the initial total knee replacement. It is important to choose a surgeon that is experienced in knee revision surgery to ensure the best possible results.
A knee revision procedure can differ from patient to patient, depending on the extent of damage in the knee. In some cases, Dr. Linschoten may only need to replace the plastic spacer. In other cases, all three components need to be replaced. Sometimes, only one of the metal components needs to be replaced.
Knee revision implants can also differ from the original knee replacement implants. Knee revision implants may have long, thick stems that are fitted inside the bone for additional support. If there is bone loss in the area surrounding the knee, Dr. Linschoten may also use metal augments to make up for the bone loss so that the knee is in proper alignment.
Most patients who have had knee revision surgery experience long-term pain relief and improved function. Full recovery from knee revision surgery may take several months. During that time, it is important to follow all postoperative instructions for the best possible results. Dr. Linschoten and his team are committed to helping patients through the recovery process and are happy to answer any questions you may have before or after surgery.
