I've had knee problems. I have to spin on my heel, and I have to wear shoes that don't have much tread. If I wear anything with a lot of tread then my foot sticks in the grass and I can't spin on my heel, this causes tremendous knee torque.
Stand still throws aren't necessarily less torque on the knee, and I find it harder to spin on my heel if I stand still and throw.
