Until you have regained full range of movement of your knee (can fully bend and straighten it) and good strength in the muscles. Even when you have achieved this, it is worth continuing with your exercises 2-3 times weekly indefinitely to keep your new knee in its best condition. See the Knee Replacement Exercise section for more information
How do I know if I’m overdoing it? A bit of discomfort when doing something doesn’t mean you need to stop. It should however settle within about half an hour. If pain continues for more than two hours after stopping the activity, that is a sign you have overdone it. Next time, reduce the intensity or time you do the activity for. If an activity causes immediate severe pain, do stop straight away
How long do partial knee replacements last? 98% last at least ten years, 92% at least twenty years
What happens if partial knee replacements fail? Sometimes they can be redone (known as a revision) or you would have a total knee replacement
Is knee surgery pain common? Yes, it is normal to experience pain after knee surgery for a few weeks as the skin, muscles and bone have been cut and take time to heal. This normally settles down within a few weeks
