A partial knee replacement is far more likely to require further work at some point in the future when compared to a total knee replacement.
Approximiately 10% of people who have had a partial knee replacement will require further work on the knee within a period of 10 years.
If you have had a total knee replacement, this should last at least 20 years or longer.
There are exceptions to these time frames and there are things that you can do to avoid requiring further operations in the future:
- If you are active and mobile constantly or lead a very active life, you are more likely to require future work. The advice is to take activities in moderation and to not try to do exactly what you used to do prior to the operation if you were incredibly active.
- If you are overweight, you are much more likely to need a future operation after a total knee replacement. The best course of action is to manage your weight to more healthy levels.
You can find a lot of information on Knee operations and the circumstances on which one might be offered on the NHS website.
