On a limited budget it's somewhat hard to animate someone running without making it look jerky. As recently as ''WesternAnimation/ThePerilsOfPenelopePitstop'', 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 [[http://www.youtube.com/watch?v=XNWP2Yc7XvM this animated insert]] from ''Series/SesameStreet''.

The preferred trick around this is to avoid showing the legs altogether. You can position the "camera" above the runner's waist while still showing him 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 female character has a skirt. The legs might be drawn nearly ''straight all the way down'' even while stationary, as if she doesn't have knees, thighs, or defined hips.

Oddly enough, knees seem to be a little too flexible in the TwistedKneeCollapse.

* Aside from having a (rather notorious) problem with feet and pouches, RobLiefeld has done this, with both men and women. Although the women tended more to have ''one'' knee that seemed to branch out into the rest of each leg.

* Sekoila Zarner from ''WebAnimation/ZanyToTheMax'' has no knees. Because of this, the way she walks is very interesting. Her legs spin rapidly as if around an axis, to the point where WheelOFeet is used.

* [[LampshadeHanging Lampshaded]] in ''LegoIsland'', which, since all the characters are LEGO minifigs, displays this by default..
-->'''Papa Brickolini:''' I have a bad feeling about this, [[MySignificanceSenseIsTingling I can feel it in my knees.]]
-->'''Mama Brickolini:''' Papa, you are just imagining things!
-->'''Papa:''' Imagining knees? ...You're probably right.
** Also [[LampshadeHanging lampshaded]] at one point in the LEGO webcomic ''FabulandHousewives''.
* The main heroine of ''Narbacular Drop'', the game whose team was hired by Creator/{{Valve|Software}} to work in the SpiritualSuccessor and EvenBetterSequel called ''VideoGame/{{Portal}}'', was called Princess No-Knees--but it's not immediately obvious whether she lacks them, as it's a nickname referring to her inability to jump.
* ''VideoGame/ZakMcKrackenAndTheAlienMindbenders'' mentions and animates the aliens as having no knees. They make a two-frame movement animation with rapid footsteps. In contrast, humans are given a distinct bend in the knee, and make less frequent steps.

* In the 2009 ''WebAnimation/HomestarRunner'' [[HalloweenEpisode Halloween]] [[http://www.homestarrunner.com/ween09.html toon]], "[[DoomyDoomsOfDoom Doomy Tales of the Macabre]]", Strong Sad removes Homestar's knees--to no very great effect.
** Well, it slows him up a bit, but as a Doomy Tale of [[{{Malaproper}} Macramé]], it isn't very scary.
*** Turning Homestar ''into'' macramé, however...

* Pintsize from ''QuestionableContent'' originally had no knees or elbows, but during the course of the comic he happily received upgraded limbs.

* [[{{Cloudcuckoolander}} Pinkie Pie]] from ''WesternAnimation/MyLittlePonyFriendshipIsMagic''' has a humorous backward-running style that seems to suggest she has no knees whatsoever in ''Swarm of the Century''.
** In ''One Bad Apple'' (and other episodes), some scenes show she does have knees...only, they happen to bend in the opposite direction horse limbs are supposed to bend!
* Naturally, being another Franchise/{{LEGO}} adaptation, ''WesternAnimation/TheLEGOMovie'' features this with its characters, which is lampshaded when Emmett does "jumping jacks".
* Averted in Franchise/{{Ninjago}} and Franchise/LegendsOfChima, where characters bend their limbs despite also being LEGO minifigures.
