Is a knee revision total replacement?

No, a knee revision is not a total replacement. A knee revision is a surgical procedure that involves replacing part or all of a previously implanted knee prosthesis. It is usually performed when the original prosthesis has become damaged or worn out, or when the patient is experiencing pain or stiffness in the knee. A total knee replacement, on the other hand, is a surgical procedure that involves replacing the entire knee joint with an artificial implant. It is typically performed when the knee joint is severely damaged or arthritic, and when other treatments have failed to provide relief.
