What percentage of knee replacement surgeries are successful

Why is knee replacement needed?

Knee replacement, which is also known as arthroplasty, is a complicated surgical procedure to replace the damaged knee joint with artificial knee joints of metal and plastic. You may need to undergo knee replacement surgery if you have:

  • Severe, chronic knee pain that refrains you from performing daily activities and disturbs your sleep.

  1. Total knee replacement: It involves the replacement of the joint surface at the end of your thigh bone and the top of your shinbone. If required, it also includes replacing the under-surface of your knee cap.
  2. Unicompartmental partial knee replacement: If osteoarthritis has affected parts of your knee, mostly the inner side, then partial knee replacement is conducted.
  3. Kneecap replacement, also known as patellofemoral arthroplasty: Involves the replacement of the kneecap and its groove.
  4. Revision or complex knee replacement: There are many reasons responsible for revised knee replacement. It is mainly second or third time replacement when the first time surgery fails due to severe arthritis, loosened implanted device, etc.
