I am enjoying this thread so much, and reading these posts reminded me of something that is easy to forget: that each knee is SO individual!
STANDING: Standing for a long time is easy for me. My new knee is so much stronger than my other knee, and most of my weight is held by the new knee while I stand.
ROM: My last ROM measurements back on September 10th were 85 degrees flexion, 17 degrees extension. Not great, right? I heard somewhere that bad extension is supposed to make stairs really tough. And yet I discovered yesterday, when I tried stairs for the very first time, that I have zero problems going either up or down them, foot over foot, while holding one stair rail like I have done all my life.
SHOES: By now (11 weeks) I do best wearing my Teva Tirra sandals instead of my New Balance running shoes, that I had to wear for a number of weeks at the beginning when my foot and leg were so badly swelled up that my Tevas wouldn't fit.
But you know what? I am SO GREEN WITH ENVY when I read about how far you two are walking. I am working on it and can walk farther now than I could. I know I need to build up my leg muscles after spending years sitting in a chair. Meanwhile, a half mile sounds amazing to me and like a very distant goal, even using my rollator.
We'll get there! I think this is analogous to what moms sometimes see (and worry about) in early childhood development. Some kids learn to read early but can't use scissors. Others can climb to the top of the kitchen cabinets but can't talk. And vice versa. But they all eventually get to the point where they can read, talk, use scissors, and climb.
