Chain gang member hurt during Saints-Lions game suffered dislocated knee

I saw it on live TV, it was gruesome and the guy was screaming....ugh, hope his surgery goes well and he makes a full recovery.....
Worst pain I've ever experienced, and I've been stabbed and slashed in knife fights before. My ankle was in line with my hip. Lucked out and miraculously didn't tear anything at all. Orthopedic surgeon said he'd never seen anything like it. Knee clicks a little going up and down stairs and I can tell when rain is coming, though.
