cruciate ligaments (cruciatum), allowing a very large range of motion (extension and flexion) of knee
The principal movements occurring at this joint are flexion and extension of the leg, but some rotation also occurs in the flexed position.Flexion and extension of the knee joint are very free movements.
Flexibility is measured by the range of motion. The range of movement is measured by using a goniometer: hip flexion, hip extension, hip adbuction, hip adduction, shoulder adduction, shoulder fexion, shoulder extension, elbow flexion/extension, and knee flexion/extension.mile run
Several joints allow range of motion, it depends on what kind of range of motion you are talking about. Ball & socket joints (such as the shoulder) allow circumduction, abduction and adduction; hinge joints (such as knee and elbow joints) allow flexion and extention.
Extension. Extension increases an angle, as in straightening a joint. During extension, the knee or elbow are straightened.

They are hinge joints. The elbow has only one plane of motion (flexion & extension); however, the knee is considered a "modified hinge" because it has the flexion & extension as well as a rotational (pivot) component as well.
Active range of motion is when a joint is moved through its range with the person moving the joint him or herself. Passive range of motion is when something besides the muscles of the joint does the moving. So if I were to bend someone else's knee (and they didn't help) it would be passive range of motion. But if the person just moves his or her joint, then it is active.
It depends on the joint. The hip joint, for instance, has far more range of motion than the knee joint.

In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.
Both the left and right knee contain a group of muscles referred to as the flexor. When these muscles are contracted, it creates the process known as flexion of the joint.

The quads give flexion movement at hip and extension movement at knee joint. While the hamstrings give extension movement at hip and flexion movement knee jiont.
hip extension and knee flexion
pivotal hinge joint that allows flexion, extension as well as slight medial and lateral movement.
