Is the Knee a Hinge Joint?

The common idea describes the knee as a hinge joint.
However, a hinge requires an axis around which to rotate.
In a real body we neither have a supported axis or even just a single option for knee movement.
The knee has multiple planes and directions of mobility that can be used in different yoga postures, or when walking, running or standing.
