You will do just fine - try not to dwell on it , it will only make you more nervous. Just think of how much relief you will be getting without being in pain or having limited movement. There is no getting around the fact that the first two weeks are rough , everyone I have talked to says the same thing . BUT , rough does not mean you will be in excruciating pain 24/7 - they will give you meds to make you comfortable - I am two and half weeks - almost three
and I drove to work this am - it was actually my left knee , I originally put my RIGHT knee - kind of ironic that my right knee was always my bad one - until the last year . Anyway - you will do fine just be uncomfortable for a couple of weeks. Hopefully you have a recliner - or couch - that is comfortable that you can lie back on - important to try to elevate the leg and ice ..ice...ice... -and you don't want it so low that's its tough for you to get up and down . Hopefully you have someone at home that can help you for a few days after surgery - you will need some help getting changed etc . Good luck - don't fret - you will do fine !!!
