Tk. Just a point about fatigue. I remember at about week 5 trying to wash car, and how exhausted I was after. The healing process takes everything you have energy wise and directs it to the body. It is a long recovery period before you get that energy level back. I am betting since you are allot younger than me, that your recovery will be much faster than mine was, but don’t let it discourage you , cause it does recover. I am guessing 6 months from now you will be quite pleased you had the knee done.
