It's pushing the joint instead of accidentally or causing direct impact. The pushing will cause more damage.
if i saw your pattern of attack. i would lift my leg. a foot against an elevated shin, or a raised and bent knee is doing no damage.
if i don't see it, i would be screwed.
i understand the dangers of it. i don't argue against that but it's not impossible to avoid the damage either.
