How long will my new knee last?

Around 40,000 knee replacements are performed each year in Australia and New Zealand and for the vast majority of patients, joint replacement provides relief from pain and improved mobility for many years.

Many knee replacements can last 10 to 20 years or more, but all joints wear with time and may require revision surgery. According to the National Joint Replacement Registry in Australia, primary total knee replacements done for osteoarthritis have a success rate of 93.9% at 11 years. 1

Your activity levels and weight are two factors that influence the rate of wear. Some of the newer materials can mean joint replacements last longer. By understanding the activities to avoid, you can also prolong the life of your new joint.

Restoring your mobility for the long term

If arthritis or knee injury is limiting your everyday activities, such as walking and bending, and you still experience pain when resting, your doctor may recommend knee replacement surgery. It can also overcome the stiffness in your knee that limits your ability to move or lift your leg.

Knee replacement surgery is considered after careful diagnosis of your joint problem. If anti-inflammatory drugs or if other treatments, such as physiotherapy, are providing little pain and mobility relief, you may wish to discuss this option with your doctor.
