Thank you, LindaO, sewhat, Tykey, kneeper, and lovetocookandsew!
OK, brag time here:

Just finished today's PT session, and had great ROM improvement! Here's my ROM so far, with today's in red:
August 15: 68 degrees
August 16: 68 degrees
August 19: 69 degrees
August 21: 82 degrees
82 degrees today! Never expected that. Bear in mind that I am about as far from an athlete as you can even imagine someone to be. Also, I was able to do each of my exercises a little bit better than I could on Monday, and could even do heel slides (which I couldn't manage to do, two days ago).
Also the PT was really pleased that I could get on and off the bed unassisted. Me too.
I asked her when I would be able to progress from my Plain Jane walker to my rollator walker (which I used for three years before surgery). I was expecting her to say, "oh, six months or a year" but instead she said, "pretty soon, as soon as you get a good solid gait and yours is improving, so maybe 1-2 weeks".
OK, that's the positive news from me to you, for today. The (slightly) negative is that I was up almost all night with back-of-the-knee pain, zingers, cramps, you name it. I should have taken two pain pills at bedtime again, but thought I could cut back to one. Sure learned that lesson.
