I'm trying to have a character have a pretty bad knee injury, but I have no idea what's realistic.
My character (Male in his mid to late 30's). Long story short I have him on the ground while a much larger/heavier/stronger guy stomps (once or twice) on my guys knee.
Now I want this to be a pretty serious injury. like the guy might need a couple surgeries, not being able to walk for a bit, physio and maybe even needing a cane for the rest of his life, even if he doesn't need the cane, his mobility should not be the same.
I have no idea what type of injury could cause this (I know knees are wonky) but I need to know if my situation is realistic (the stomping is important) And what kind of damage would need to be done.
I don't mind doing the research on the prognosis, but I need to know what type of injury this could be (broken kneecap? I know there are a lot of tendons in the knee)
Much help would be appreciated!
