Complex or revision knee replacement

Back to What are the different types of knee replacement surgery?

Some people may need a more complex type of knee replacement. The usual reasons for this are:

  • major bone loss due to arthritis or fracture
  • major deformity of the knee
  • weakness of the main knee ligaments.

These knee replacements usually have a longer stem, which allows the component to be more securely fixed into the bone cavity. The components may also interlock in the centre of the knee to form a hinge to give greater stability. Extra pieces of metal and/or plastic may be used to make up for any removed or badly damaged bone.

This type of operation may be needed if you’re having a second or third joint replacement in the same knee, and could be better from the start if you have very severe arthritis..
