All animals that use their limbs for locomotion have knee joints on their hind legs, just the same as humans. Creatures without legs would also have no knees.
Some of these include:
Snakes
Invertebrates
Fish
Marine Mammals
When watching 4 footed animals it often appears that they have no knees, this is because to run fast the knee has migrated up to the top of the leg so appears to be a hip (it remains in the same place on the front limbs
Whales and dolphins.
Snake
A person can lose weight to make their knees lose some extra bulge, or they can have plastic surgery done on their knees. Other than that, there is no way a person can get smaller knees.
if your knees are out of line, you will not be able to walk when you get older and they are unfixable

Joints make it possible for your knees and ankles to work.

No. Actually, the elephant is the only animal with four knees.
A camel? A camel?
The knees of the warthog are padded, callused and hairy. The warthogs knees are this way because they spend a lot of time kneeling to eat in the prairie grasses.
Having knees...
Elephants are the only animals that have four knees. Their hind legs and fore legs bend just the same. Elephants can gain top speed of 7m/sec without running.
2. A previous answer here said four, however only elephants have four knees. A rhino's legs rotate like a dog or cats, so they only have 2 knees.
Most mammals (e.g. horses and dogs) have knees that bend the way human knees do. However, when you look at a mammal's leg, the knee is not in the same place you're used to finding it. Many four-legged animals actually walk on their toes, and have elongated feet and ankle bones. Take a look at a dog or horse skeleton on the internet, and you can see that what seems to be a "backward bending knee" is actually the animal's ankle!
It means that you get down on your hands and knees, and stand like a four legged animal, 'on all fours'.
I don`t know... my Grandpa??? NO really it`s a wild bore.
Yes, giraffes do have knees.
This concept is referred to as a misconception, because animals do not have backward knees. The part you think is a backward knee is equivalent (homologous) to your ankle. Notice that your ankle bends "backward." Animals have forward bending knees, just like you, but they are often overlooked. Look higher up on the animal and you will see their homologous knee. In some animals, there is a lot of muscle and/or loose skin over the area, so it looks like a rounded hunch near their hips.Stand up. Lean over. Bend your knees a bit. Now stretch your t-shirt down over your knees. This is how you might imagine many animals having 'hidden' knees.
