Sorry for the delay JMall, it's been a crazy month and a half.  Coach Kiser and I just acquired a new facility for our gym today and shuffling paperwork and finances around plus teaching, keeping the family happy, etc. etc. has kept me on the run.

But I have been thinking about how to answer this question.

I've never seen or experienced it myself, the inside leg kick paralyzing the leg yet.  But I do know that you will experience gradual muscle function.  And it is painful enough that you will eventually have to do something about it, which usuallys sets up other techniques.  Khuen Khru Will Bernales, my instructor is notorious for going to the inner thigh/thighs  (sometimes he'll go left kick to left inner thigh, right kick to right inner thigh), just to get you to give up the outside angle.

I've also experienecd excruciating pain when Coach Billy Robinson put his elbow into the femeral artery there on me (see the shin lock clips).  So I know it can be extremely painful.  But to answer your question, I've never seen anybody KO'd from there.

That doesn't mean it isn't an important tool for your arsenal though.  I've seen very few people KOed with the Jab, but it's one of the most important punches in the game.  IMHO.

Ah, I think I may have found one.

Check it out at the 1:00 minute mark.  That inside leg kick really seems to have done some damage.  TBA Thai Tests are No Joke!
