how long do knee replacement last
Back to Knee replacement surgery. For 80â90% of people who have total knee replacement, the new joint should last about 20 years, and it may well last longer. If you've had a partial knee replacement, you're more likely to need a repeat operation â about 1 person in 10 needs further surgery after 10 years. The chances of needing another operation is greater if you're overweight and/or involved in heavy manual work.
