Knee Replacement Surgery

Knee replacement surgery is usually necessary when the joint is worn or damaged, making it difficult to carry out normal daily activities and causing severe pain even when resting.

You may need a replacement if:

  • you are in regular pain which makes it difficult to carry out every day activities, or is having a disabling effect on your ability to move normally,
  • you cannot walk very far or find stairs difficult and require the use of a stick, and
  • your knee is becoming stiff and cannot bend easily or without causing pain.

If you are suffering from these symptoms, we would advise you to contact your GP in the first instance, who may refer you to an Orthopaedic Surgeon to discuss possible treatment options.
 
In knee replacement surgery, the damaged knee joint is removed and replaced with an artificial joint (also known as a prosthesis) made of a metal alloy or ceramic. The full surgery usually takes between 45 and 90 minutes to complete.
