my knee...

Well about 10 months ago I was wrestling with a friend and had a bad injury... tore my meniscus, LCL and broke a piece of bone off my knee that is now pinned back.

My leg got skinny and weak. I gained some mass back now, but it hurts to run and squat down hard.

Has anyone ever been denied for a bad knee? My doctor says I will be 100% most likely, within a couple years. Personally I think I'll get better.. many players in the NFL have had similar injuries and they're faster than ever (of course w/ lots of training and rehab)

Is acadamy very stressfull on the knees/legs?

thanks for the input
