It got its name because it acts as a hinge, only opening and closing a certain distance. Your elbow is a hinge joint. Think of your elbow as a hinge on a door in your house. The door is your forearm and the door frame is your upper arm/body.
In our joints our hinge joints are located between two bone our hinge joint is our elbow.

Hinge type of joint allowsflex-ionandextent-iontypes of movement. Tibia and Talus forming hinge joint they allow above type of movement.
Hinge joints include a cylindrical bone end that fits into a groove, called a trochlea, on the other bone. One example is your elbow.
Hinge joints
The theorem emulates the action of a hinge. As the angle of the hinge is increased the distance between the free edges increases.
A previous wiki answer from Gerry Sutton.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 wellRead more: What_type_of_joint_is_found_in_the_knee_and_elbow
The structural name is a hinge joint because it moves like a hinge. A ball and socket would be if a head of one bone fit into a fossa on another. The knee joint consists of two articulating bones, the femur and tibia. As well the patella (knee cap) lies infront of this joint.
Patella!! ---- There are three bones that make up the knee joint: the distal end of the femur, the proximal end of the tibia, and the patella, which is a sesamoid bone within the quadriceps tendon that helps provide better leverage for extension of the knee.
knee and the elbow joints are hinge joints.These joints occur where the convex surface of one bone fits into the concave surface of another bone, so making movement possible in one plane only. Hinge joints have ligaments mainly at the sides of the joints.
