On a limited budget it's somewhat hard to animate someone running without it looking jerky. As recently as
The Perils of Penelope Pitstop, animators tended to draw legs moving with very little bending of the knee, sometimes at even a full run. In real life, this would be more than a little painful, as shown in
this animated insert
from
Sesame Street.
The preferred trick around this is avoid showing the legs altogether. You can position the "camera" above the runner's waist while still showing them swaying about a little, or aim the shot straight at the feet, which also doubles as looped footage.
Some artists go (stop?) an extra step if a character has a skirt. The legs might be drawn nearly
straight all the way down even while stationary, as if they don't have knees, thighs, or defined hips.
Oddly enough, knees seem to be a little too flexible in the
Twisted Knee Collapse.

Video Games
- Lampshaded in LEGO Island, which, being as all the characters are lego minifigs, displays this by default..
Mama Brickolini: Papa, you're just imagining those things!
Papa: Imagining knees? ...Maybe you're right?
- The main protagonist of Narbacular Drop, the game whose team was hired by Valve to work in the Spiritual Successor and Even Better Sequel called Portal, was called Princess No-Knees — but it's not immediately obvious if she lacks them, as it's a nickname referring to her inability to jump.
Web Animation
Comics
- Aside from having (rather notoriously) problem with feet and pouches, Rob Liefeld tends/tended to do this, with both men and women. Although the women tended to more have one knee that seemed to branch out into the rest of each leg.
Webcomics
- Pintsize from Questionable Content originally had no knees or elbows, but during the course of the comic he happily recieved upgraded limbs.
