"Knee replacement"

I had a half knee done in dec 2013 after lots of smaller op and I could not be happier I now only take four pain killers a day which is so much better than before as I was on at least 18 .i walk really well and am back to work with a job that I stand up all day it does swell by the end of the day but that is the least of my worries I can only say if you do as the dr ask don't over do things , keep the wound clean ice it often and do the exercises you should be ok.
