Today wasn't the best day, I ate too many Halloween treats...
Your body does also need some fat
Well, I gave it some today, LOL.
Lots of exercise today, about 4 hours between the gym and physical therapy, tired tonight. Knees a little sore, but not too bad.
Had the 4 week physical therapy evaluation today, had 0 degrees on both knees without pushing, that surprised me. And flexion was 130 degrees, both knees, good news. However the right one still hurts a lot more than the left. Therapist says I have pretty much made the extension and flexion goals and he would start shifting my therapy to more strength building, I guess that's good news.
Short answer: probably, if you're working on it actively.
Very long answer: given how long it's been since you were last able to extend your knees those last 10 or so degrees I assume your vastus medialis muscle (one of the four "heads" of the quadriceps femoris, basically only important over those last degrees and rather prone to laziness after trauma or restriction) is mostly or completely inactive. If you don't have specific exercises for it yet: the best way I've found to activate it is to put something soft (like a rolled-up towel) under your knee when lying on your back and pushing down (actively, no outside help) while mentally focusing on the vastus medialis muscle (look up its position: if it activates you can generally feel it just proximal of the knee on the frontomedial side of your upper leg). Make sure not to arch your back while doing so. You may need a relatively thick roll at first but after a few tries you should be able to unroll it a bit and still feel tension. Once you can actively push down even on a reasonably thin roll you try to raise your heel while maintaining downward pressure with the back of your knee. It often feels like nothing is happening at first and especially with both legs having been restricted for years there's no guarantee it will work but the muscles are still there so it generally just takes practice and mental focus.
Llama, you are a good friend, and a real expert. I read your post before going to PT today and quizzed him a bit about what you said. He did not disagree, but your advice was clearer and more to the point, thanks for that! I have done some research on the vastus medialis muscle, I can see you are right, and I got some exercise ideas. Also discussed it with the trainer at the gym, she seemed to understand as well and has ideas. She did know what the vastus medialis was, well ahead of me. Thanks again for taking the time to help me, I understand you cannot diagnose me without seeing me, but you have given me some very useful ideas to explore.
Well done on mowing the lawn unaided - another milestone reached!
Thanks, it was a riding lawn mower, but I wasn't sure I could get on and off, or empty the clippings bags. No problem! That felt good.
We had fish yesterday but it was canned

I do like it though, but I think I would eat fish a lot if we had heaps in our freezer.
I will be eating a lot of it. I also eat, and like canned fish. Just don't need it right now.
