I had a left TKR July 13, 2015. I had a tough time of it in the beginning because I wasn't able take pain meds. They all made me so sick. I'm still in therapy working on stamina and going down stairs. I'm starting back to work in a week and a half and I'm going have to be on my feet for 10 hours or more a day. It definitely has been 2 steps forward and 1 step back. I cried twice at PT. Once was when my frustration on how slowly I was improving pushed me to the edge. The second time was when I had developed scar tissue that my therapist had to work through. I haven't given up, but as of now I have no plans to ever have my other knee done! Just keep at it and the only schedule on recovery varies between everyone.
