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.
The elbow moves in two planes of motion: sagittal (flexion and extension) and frontal (adduction and abduction).
The movement permitted by a hinge joint is extension (opening) or flexion (closing). The elbow is a hinge joint. When you "flex your muscle", you preform a flexion movement (closing). The opposite is extension as in handing a cup to someone..
Frontal Plane about the anterioposterior axis
The knee and elbow both are uniaxial joints. This type is a synovial joint that permits movement around only one axis and in only one plane. The articulating ends of the bones form a hinge-shaped unity that allows only flexion and extension.
The elbow can rotate on one plane, allowing flexion and extension movements. The knee can also rotate on one plane, enabling flexion and extension, as well as a slight degree of internal and external rotation.

Flexion and extension movements occur in the sagittal plane. Flexion involves bending at a joint to decrease the angle between two body parts, while extension involves straightening at a joint to increase the angle between two body parts.
Frontal Plane about the anterioposterior axis
Sagital Plane Exercises are a forward to backward movement or front to back movement. Inverse Crunch Floor to waist Front Squats Knee Flexion and extension Trunk Flexion and Extension Shoulder flexion and extenstion

The knee contains a hinge joint, which allows movement in one plane, similar to a door hinge. The elbow contains a hinge joint as well, enabling flexion and extension movements.
No, an elbow is a hinge joint, which is considered a uniaxial joint as it allows movement around one axis only. It predominantly allows flexion and extension movements along one plane.
Trunk flexion occurs in the sagittal plane of body motion. This movement involves bending the torso forward, bringing the chest toward the thighs. It primarily involves the muscles of the back and abdomen.
Elbow joint consists of three joints:Joint between trochlea of Humerus and Ulna is hinge joint (ginglymus joint).Joint between capitulum of humerus and head of radius is also a hinge joint.Joint between Upper ends of radius and ulna is pivot joint.
