Ha--I was awake too early today with achiness in my knees and happened to open my laptop to your post--I am experiencing so much of what you're describing. And when I read back over your thread I see some more similarities--years and years of hardcourt tennis which probably contributed to these knee issues! And I also have found that when I have gone out of this forum and read anything online, it sounds like we should have this all wrapped up by now! But when I think about my trusted sources--my PT, doctor, others who have had a TKR, they say what I read here--that we are about a quarter of the way through this process. But I agree with you, it's hard to trust the process. I think sometimes it's hard for me to distinguish between this pain I may have now and the pain I had from my formerly arthritic knee, so it's hard to get it into my head that it will improve further.
