During a revision hip or knee replacement procedure, an artificial hip or knee joint prosthesis is repaired. In some cases, artificial hip and knee joints become damaged as a result of general wear and tear over time. They can also be damaged as a result of an infection.

Why would a joint replacement fail?

Sometimes, when an implant is placed, the bone does not grow onto the artificial components, which means that the prosthetic joint is too loose. In this case, the implant may need to be replaced. The artificial components may also loosen over time, causing considerable pain and impaired movement.

In cases of infection, bacteria attach to the prosthetic joint, causing pain and loosening. Revision surgery is often recommended when there is an infection, as it is the most successful treatment option.

What does a revision joint replacement involve?

A revision hip or knee replacement works by repairing any damage and helps to restore proper function and movement. During the procedure, Dr Ackermann will remove the damaged artificial hip or knee joint and replace it with a new one. It is possible that more than one of these procedures be required. In cases where more than one procedure is necessary, old scar tissue is removed, and any infections are treated. Once the infection has healed properly, a second procedure is conducted during which a new artificial hip or knee joint is placed in the correct position. In some cases, the entire prosthetic joint may need to be replaced, while in other cases, only some of the artificial components may be damaged.

Dr Ackermann also makes use of a specialised soft tissue tensioning device for both modular exchanges and full revision knee replacement surgery to allow for better outcomes for patients with a stiff and painful or unstable and loose knee replacement.

A revision hip or knee replacement procedure is generally very effective, and helps significantly in relieving pain and improving movement. That said, the procedure is quite complex, and as such, requires adequate planning. Dr Ackermann is available to address any questions or concerns you may have about the surgery and will advise you whether or not it is the most appropriate form of treatment for your unique circumstances.
