I am assuming advanced osteoarthritis? Wear and tear that requires replacement?
If so, please look into the options for pain relief before surgery. Hopefully your doctor has told you it is best to put off surgery as long as possible because the artificial joint cannot repair itself and will wear out much more quickly than your natural knee. I have some alternative ideas on my website.
