Total Knee Replacement

Total knee replacement surgery is a very effective treatment option for end-stage severe knee arthritis which is not suitable for a partial knee replacement. The main indication for total knee replacement is pain that is no longer effectively controlled by conservative measures and when less invasive surgical options are no longer deemed appropriate.

Surgery for total knee replacement involves removing small sections of bone and damaged cartilage from the end of the femur (thigh bone) and another section from the top of the tibia. The surfaces are then replaced by metal components using a special bone cement. A polyethylene bearing insert is placed between the metal components. The patella (kneecap) surface may be replaced with a plastic button.

The results of modern knee replacements are very good. In general, only a very small percentage (approximately 5%) of total knee replacements fail within 10 years. However, the younger, heavier and more active you are, the greater the risk that your knee replacement may wear and fail quicker. This has to be often factored in when recommending knee replacement surgery. Furthermore, despite an excellent outcome for the majority of patients, a small percentage of patients can experience some chronic pain after knee replacement.

Revision Total Knee Replacement

If your knee replacement fails either due to wearing out, becoming loose or sometimes due to infection, stiffness or instability, then a revision procedure may be required to replace all of the components. Revision surgery can be more complex and technically more demanding than your original knee replacement.
