How long will my joint replacement last? – Longer than we thought

By Cris Kellett Posted 20.02.2019

A common question asked by people contemplating hip or knee replacement surgery is how long will the new joint last. A recent article by Evans and colleagues in The Lancet (volume 393, issue 10172) suggests that they last longer than we originally thought.

The researchers found the following:

  • Hip replacements: 89% lasted 15 years, 70% lasted 20 years, 58% lasted 25 years
  • Total knee replacements: 93% lasted 15 years, 90% lasted 20 years, 82% lasted 25 years
  • Partial knee replacements: 77% lasted 15 years, 72% lasted 20 years, 70% lasted 25 years

In addition to indicating that the costs to the NHS of joint replacement surgery may be reduced due to their longevity, it may also indicate that joint replacement surgery could be undertaken sooner to help younger patients with osteoarthritis.
