There are several possible advantages of knee replacement surgery. These include:

• freedom from pain
• improved mobility
• improved quality of life because everyday activities and exercise are easier.

Research has shown that four out of five people who’ve had knee replacement surgery are happy with their new knees. For those people who aren’t happy, the main cause for dissatisfaction is continuing pain which may not be due to a problem with the operation. This is more of a risk if you have relatively minor joint damage (which may still cause severe symptoms) before surgery. If your joint damage isn’t very severe it may be better to carry on with non-surgical treatments rather than risk a poor outcome from surgery.
