Revision knee replacement is a surgery for patients who already have an artificial joint.
For most patients, knee replacement surgery resolves chronic pain and restores function to the knee, enabling them to live active, rewarding lives. But, unfortunately, in a few cases, something might go wrong with the new knee.
If you're experiencing knee pain and swelling, stiffness, or instability, it could be due to a failure of the replacement knee that requires further surgery.
Dr. Pearson might recommend revision knee replacement if you have pain and loss of function from:
Bacteria could get into the joint during or after the initial surgery, causing a painful infection. Revision knee replacement may be necessary to treat it and make sure the joint is secure.
Over time, parts of your replacement knee can wear or loosen. These problems are more likely to affect patients who have knee replacements at a younger age since their life expectancy could be longer than that of the replacement joint.
If you fall on your artificial knee, it could result in a periprosthetic fracture – breaks in the bones surrounding your implant.
The ligaments that enable you to bend your knee and help keep it stable may suffer damage leading to joint instability, where your replacement joint weakens and may give way. Physical therapy and bracing can often resolve this issue, but where they can't, revision knee replacement may be necessary.
If you aren't regaining a reasonable range of motion after your original knee replacement, you may have a build-up of scar tissue around the joint. Dr. Pearson might be able to manipulate your knee under anesthesia to break up the scar tissue, but if this is unsuccessful, he can carry out revision knee replacement surgery.
Revision knee replacement takes longer and is more technically challenging than your original surgery. The implants used for revision knee replacement may be different from the original parts.
Dr. Pearson first needs to examine the implant, bone, and surrounding tissues. He may then remove the components if they're worn, which he does with great care to avoid the loss of natural bone.
He treats any infection present and inserts an antibiotic spacer. Some patients need additional joint support using platform blocks and metal augments where there's significant bone loss.
