A knee revision replaces prosthetic implants in a person who previously had a total knee replacement. In this surgery, known as a “reoperation,” an original prosthesis is removed and a new prosthesis put in place. Over time a knee replacement surgery could fail. If this occurs, the knee can be painful and swollen. It can also result in stiffness and instability of the joint, making daily tasks difficult. Therefore, if your knee replacement fails, a knee revision may be required to treat the pain, inflammation and instability.
Revision surgery is often recommended if:
- You had an infection in the replaced joint
- Instability in the replaced joint
- Wear and tear
