Right. I'm starting to understand the distinction. I thought my knees were just giving way, but now I am considering the possibility that the hyperextension is compensatory. This is very helpful.

I suppose I will consider PT. Getting to a regular appointment will take so much of my energy, that I will have to be convinced that there's a reasonable chance it will help me. But maybe he can just see me a few times to give me some tips or something.
