I tore the meniscus in my right knee very bad,...had to have a bit of surgery. It still acts up a but, but overall, it's functional.

Once, long after the surgery I stood up from a low chair and heard *POP*. I don't know what it was but it was in the crook of my leg behind the knee. It hurt for several weeks and I was figuring I needed some more surgery. But the pain gradually faded away.

I'm a lot more protective of my knees than I used to be, though. I stand up from a chair slow and push with my arms.

I don't want any more knee trouble than I already have.
