After having a knee replacement, you may expect your lifestyle to be a lot like it was before surgery - but without the pain. In many ways, you are right, but returning to your everyday activities takes time. Being an active participant in the healing process can help you get there sooner and ensure a more successful outcome.

Even though you will be able to resume most activities, you may have to avoid doing things that place excessive stress on your “new” knee, such as participating in high-impact sports like jogging and sitting on floor. The suggestions here will help you enjoy your new knee while you safely resume your daily activities.


When you are discharged, Healthcare team will provide you with information to support your recovery at home.
