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.
Joints that allow movement in a single plane are called trochlear joints, also known as hinge joints. Examples of such joints are the knee and the humero-ulnar joint of the elbow. Technically the knee does rotate slightly in the last few degrees of extension which is called the "screw home mechanism", but is still considered a hinge joint.hinge
Elbow does not belong because it is the only one that is not located on the leg.
The three main types of joints in the body are: ball-and-socket joints (hip and shoulder), hinge joints (knee and elbow), and pivot joints (neck).

Hindge joint
Joints at the knee and elbow are hinge joints, designed to move in one primary direction (flexion and extension). The structure and shape of these joints limit rotational movement to protect them from injury. Rotation at these joints is mainly performed by the muscles and bones of the forearm and leg rather than at the knee or elbow joints themselves.
