What are the different types of knee replacement surgery?

ANSWER

There are four main types:

  • Total knee replacement is the most common type. The surgeon replaces the surfaces of the thigh bone and shin bone that connects to the knee.
  • Partial knee replacement may be an option if arthritis affects only one side of your knee and you have strong knee ligaments.
  • Kneecap replacement replaces only the under-surface of the kneecap. Total knee replacement surgery has a higher success rate.
  • Complex (or revision) knee replacement is for those with very severe arthritis or who have already had more than one knee replacement surgery.
