I didn't know what the operation game was, so I looked it up. The guy, indeed, is clearly awake:
I only learnt about charlie horse from King's early novel The Long Walk. I am not sure I've evr encountered the wrenched ankle, which, come to think of it, is strange, so I've probably just forgotten. What's much stranger to see is the bread basket — it looks as if it doesn't even belong. The anklebone connected to the knee bone is just weird.
Google says the newer version of the game has also acquired brain freeze.
