An update for you...at 5 weeks, LTKR was Monday, 2/23...
I'm improving every day. I still get pretty tired if I don't take a nap but not much pain now and I'm sleeping through the nights. I took a little outing by myself to the grocery store on Tuesday. Got a few things, did pretty good, then laid down for a nap

My knee is doing very well but I've been having lots of trouble with my left foot-ankle. My knee surgeon didn't seem to think too much about it so I went to our podiatrist yesterday.
I have a stress reaction (sprain not a fracture) on my 4th metatarsal bone (top of foot in the instep of 4th toe). As some of you know - because I've been telling everyone - it started weeks ago with my initial foot exercises. (I think the office PT sessions made it worst even though I kept telling them about it.) The podiatrist gave me a foot wrap and said to continue to rest my foot for another 4 weeks and it should heal without complications. My OS released me from PT last week but I'll still do home exercises that strengthen the knee but will avoid the ankle-foot ones.
I've been doing a little google research and this stress reaction is common to ballet or athletes who do repetitive motion, but it does not seem to be normally related to TKRs. At least that I can't find any studies linking them. Nevertheless, if others are having foot problems I suggest they see a podiatrist also.
So now I using the small brace from CVS on my left foot but my knee continues to heal beautifully. I'm still planning to do my right knee June 8. I see both doctors in early May to get all checked out. Again thank you for all your prayers and best wishes. Great site!!!
Hope
