i know that soccer has a really high frequency of injuries,
That's how I blew my knee out, tis true. My leg was extended, someone else did a sliding tackle for the ball. Their outstretched lower leg slid over my foot, completely pinning it to the ground, while their rest of their weight and momentum all impacted the side of my knee, where there was no way for it to move to absorb the impact. Needless to say, the knee gave way completely.
From what I was told later, the crunch of my knee imploding was so loud, people on the sidelines could hear it over all the yelling and shouting of the spectators. I don't remember the actual impact, all I remember is seeing the guy's leg start to slide over my foot, and the next thing I knew, I was flat on my back, and my coach was kneeling over me asking if I was OK. Knee hadn't started hurting yet by then, but I could tell there was definitely something very wrong with it. Then spent 6+ months in an immobilizing brace, etc.
Still, it was in no way a life-threatening injury. Soccer there are a lot of injuries, but they're generally joint problems, broken bones at worst.
