1. Yes I can. Except for my right knee hurts when I do it, though I can make the pain go away if I manipulate how the foot steps up.
This was a rhetorical question too, so I'm pretty sceptical, (or you're a civil servant in the ministry of silly walks.) At any rate, I was trying to make a clever point about the particular range of motion and loading that you've been advised against is necessary to function in day to day life — outside of a wheelchair. Sorry if that wasn't clear, I was on my iPad between clients, and somebody once told me brevity was the soul of wit. At any rate, if you keep your shins perpendicular or artificially restrict the range of motion on the knee, that force doesn't just dissipate into the ether, it goes someplace else in your body. There was a study that mechanically restricted anterior patella displacement, and that small amount of force reduction in the knee joint translated to a massive amount of torque in the hips. The human body evolved to move a certain way, and the goal should always be to move towards that freedom of movement and not away from it.
I'm schedule to see her again on Monday again, I figure I should at least give it a second time.
By all means, go and see her for an injury. That's what they're for. Just keep in mind that unless she's a sports physiotherapist she's not going to give good sport or exercise related advice. Your GP isn't likely to perform dentistry on you, after all.
She did diagnose me with PFS after all, which seems to be in line with the responses here.
I urge you to be careful about that too. None of us are physiotherapists (that I'm aware of) and none of us have any kind of imaging of any kind of any part of your body, let alone your knee. I'd say chances are the brilliant minds here are doling out some juicy tidbits of knowledge sweet as icing with zero carbs, but we're really only going off of a tiny sliver of the picture here.
