* Muscle fatigue: Katniss is utterly worn out from the fight and her previous days of survival. She has "spent every ounce of her energy" and her muscles are "aching."
* Bruises and cuts: While not explicitly described, it's implied Katniss has bruises and cuts from her close calls with Cato. She was "thrown across the arena," "impaled on a branch," and "forced to dodge" his attacks.
* Possible broken bones: The text mentions Katniss' "twisted ankle" and a "wrenched knee." This suggests she might have suffered bone injuries, but it's not explicitly stated.
Overall, Katniss is in a very weakened state, both physically and mentally. Her injuries are significant, but not life-threatening at this point. The chapter ends with her finding a small cave and collapsing inside, hoping to rest and recover.
