I know all about the clicking, at least in my case. I found that the more I bent in, in pt or whenever, it seemed like it swelled, and it got much worse. I cannot obviously tell you what to do, but...stop bending it for a few days more than necessary. The more you exercise it, the worse it clicks and then the worse it hurts, right? Give it some rest, the swelling goes down, the clicking lessens, and it hurts less. I also found that using like an ace wrap that went all around the knee cap but not over it kept me from bending it too much as well as I guess keeping it from moving to the side, which I think is what made it worse. I used that tape stuff that sticks to itself and made like a x with it all around my knee, not too tight, and used the pain to tell me how close I could actually get to my knee cap with the tape. A happy thing; the clicking doesn't happen anymore, but for once in a great while when I have lifted too much weight, and then it doesn't hurt and click for long. Good luck, I hope this helped you.
