Yeah, the first doc I went to in HS, when I hurt it in basketball, said it was ligament. They pulled tons of liquid off it. That's about all he did. What a quack. When I rehurt it in college I went to another doc who was like "Oh yeah, meniscus cartilage." At that point it was all folded up. Couldn't put weight on it. I was great on crutches though. Over thanksgiving break he did arthroscopic surgery and removed it.
So I guess now the scar tissue that replaced it isn't holding up. I know part of it is weight and part of it is old age and the inevitable. I'm in denial about both, but not enough I won't try to fix the parts I can by myself. For now.
It is the suck. But I won't be 'that' old lady. I just won't.
