The term “revision knee replacement” is used to describe when the original or “primary” knee replacement has worn out or fails due to fracture, infection or other problems and needs to be replaced.
Revision knee replacement is much more complex than a primary knee replacement procedure as there is often scar tissue, lesser amount of bone available and dysfunctional ligaments needed for stability. Often additional bone and complex knee prosthesis are needed to perform revision knee replacement procedure.
Surgery for revision knee replacement is often done through the same incision as the primary knee replacement, will usually take longer than a primary procedure and statistics show a slightly higher complication rate. The artificial joint (prosthesis) may not last as long as the prosthesis in a primary knee replacement.
