Well, I've hit 5 months! I am feeling more and more "normal." Yesterday I did over an hour of yard work with no ill effects to "lefty."

(lawn mowing over leaves not snow blowing yet!) When I think back to before the surgery where I could only walk a few minutes at a time without the knee going out on me and the grinding etc and then where I am now, I'm very pleased and definitely believe I did not do this too soon.
Even with the fibro and RA I feel I'm able to do more than in the months and years before my tkrs. I think my bend is around 110-115, but it feels comfortable bending at that range. That's a bit of an improvement from where I started before the surgery. I will keep working on stretching and increasing my activities slowly and hopefully this will enable me to do more daily activities that require bend.
My energy is back to it's usual lousy level

rather than the post op super lousy level.
I've tried cutting down my tylenol to twice a day (total 2,000 mg) but though I find the new knee would be ok with that

, everything else needs an early evening dose too or I'm too uncomfortable to sleep.

At least the RA has settled down for the most part so acetaminophen keeps me at a 2-4 pain level most of the time. If the shoulder starts hitting 5 or more again, I'll call the rheumy and see about getting it shot up with cortisone again.
