If you are running, or jogging, while throwing, there should not be any twisting, especially if you follow-through by continuing your present coarse. I like to think of it as a hybrid between a cricket "pitcher", and a javelin thrower.

Subject: [RCSE] HLG knee injury - IMPORTANT
I've noticed a lot of knee bandages and braces associated with HLG, now I
know why:
I recently switched from baseball style launch to the more common javelin
style. It is less stress on the shoulder, but mainly it eliminates wing hits
to the back of the head! But on the negative, it also places more twisting
action on the forward knee.
This is due to the different method of weight transfer. Baseball style best
uses a sinking, pendulum motion that leaves the forward knee more flexed and
allows the hip to take up rotational deceleration in the follow thru after
release. Javelin style (due to reduced shoulder rotation) requires a stiff
plank sort of rocking motion that requires a straighter forward leg and
places all body weight directly on that leg in the follow thru.
So how to compensate for this? Easy: After release you need to get right up
on your toes, to facilitate ease of pivoting the foot, and imparting greater
mechanical advantage to the knee. Then, If you observe you will see that
there are muscles in your leg that prevent twisting motion of the knee. You
are going to have to consciously habituate yourself to using them.
That is really all that there is to it. I hope everyone out there who is
into HLG and a hard launcher will take this to heart.
Best Wishes and Good Health
