Total Knee Replacement Surgery (Total Knee Arthroplasty)

Your surgeon replaces the surfaces of the thigh bone and shin bone connecting to the afflicted knee. This procedure is the most commonly performed.

Partial Knee Replacement Surgery

If arthritis affects only one side of your knee, a partial knee replacement surgery may be an option.

Kneecap Replacement Surgery

Your surgeon replaces only the under-surface of the kneecap. Some surgeons advise against this procedure, because total knee replacement surgery has a higher success rate.

Complex (or revision) Knee Replacement Surgery

You may need a complex knee replacement surgery if you have very severe arthritis, or if you have already had multiple knee replacement surgeries.
