Dirty to knee opponent's thighs?

[OldBones]

I noticed that knee bumps are pretty common for sweeping techniques, but I rarely see full on knee attacks to the thighs.  Is this considered a dirty move?  Or is this not utilized due to it being considered a low scoring attack (a la leg kicks).  That said, I see this as a potentially devastating and effective move.  Can someone explain?  Thanks.

From what I've seen I think knees to the legs are a good alternative for fighters who are too short to safely knee past the groin. And also like you said, it opens up many options for throws and distractions in the clinch. My last smoker my opponent kneed my legs and I had nothing against it, it helped him stay active in the clinch. One of the instructors at my gym, Neungsiam sets up some throws from rabbit knees.
