Knee

In human anatomy, the knee is the leg joint connecting the femur and the tibia.

Non-biped anatomy

Leg joints of quadruped mammals and of insects that have functions similar to the human knee are also referred to as knees, despite important differences. In particular, the homologies in the limbs of bipeds and of quadrupeds are extensive, but often the parts serving corresponding functions are not homologous to each other, and the homologous parts have different functions, to the extent that thinking of horses as running on their tiptoes and fingertips can be a step toward abandoning misconceptions.
