Knee replacement

In knee replacement surgery (arthroplasty), a damaged, worn or diseased knee is replaced with an artificial joint.
Why knee replacement is necessary
Knee replacement surgery (arthroplasty) is usually necessary if your mobility is severely reduced and you experience pain in the knee joint even while resting.
Before the operation
Choose a specialist who performs knee replacement regularly and can discuss their results with you. Make sure to ask them any questions you have.
What happens during knee replacement surgery
You will usually be admitted to hospital on the day of your operation. The surgeon and anaesthetist will usually come and see you to discuss what will happen.
Risks of surgery
As with any operation, knee replacement surgery has risks as well as benefits. Most people who have a knee replacement do not experience serious complications.
Recovering from a knee replacement
Recovery times can vary depending on individual and the type of surgery performed. It is important to follow the advice the hospital gives you.
