Total knee replacement surgery is generally recommended when a patient’s quality of life is being affected by arthritis within the joint and conservative (or non-operative) treatment options (such as analgesics or anti-inflammatory medications) are no longer helping.

A total knee replacement (TKR) or total knee arthroplasty is a surgery that replaces an arthritic knee joint with artificial metal or plastic replacement parts called the prosthesis.

The typical knee replacement replaces the ends of the femur (thigh bone) and tibia (shin bone) with metal components with a plastic space between them.

Revision knee replacement surgery may be recommended because part or all of your previous knee replacement needs to be revised.  This operation varies from very minor adjustments to more significant operations replacing all of the components.
