MeeWee, your post reminded me of how "not fun" the first few weeks are, but it'll change quickly
Pretty soon the crutches will not be as much for support as they will be for reassurance when you're frightened that you can't walk without assistance. Not yet, but soon
I'm now at +15 after BTKR, and winding down outpatient rehab,which was very valuable. Friday was a big day, they taught me how to get down, and off, the floor without using anything for support. No chair to lean on, just by myself in the middle of the floor. I was certain that wasn't possible, but it's just one more thing that I can do now that I couldn't be before surgery
If you're down in the dumps, so was I at +11 days. But you'll turn the corner soon, walk without assistance, even walk the dreaded steps, get in/out of the car without pain, even drive. And after about 4 weeks (for me) every week had huge improvements
And I know the PT concentration on numbers is not enjoyable, but the 'science' of walking was explained to me in terms of flexion percents. And while I don't remember the exact numbers, they know that at a certain percent you can walk somewhat smoothly, and a different percent you can walk down steps, at another you can bend your knee enough to comfortably pick something off the floor. My rehab folks also stresses numbers, but until it was explained to me that numbers translated into the ability to perform, it didn't make sense.
Good luck, joe
