A hinge joint allows for unidirectional movement, primarily permitting flexion and extension. This type of joint can be found in locations like the elbow and knee, enabling the bones to move in a back-and-forth motion along a single axis. The structure of a hinge joint restricts rotational movement, making it distinct from ball-and-socket joints.

The hip joint is a ball and socket joint. The ankle joint is a hinge joint.
The knee joint is a hinge joint that allows for flexion and extension of the leg. It is formed by the articulation between the femur (thigh bone) and tibia (shin bone), as well as the patella (kneecap).
The humerus-ulna joint at the elbow is a hinge joint. This type of joint allows for flexion and extension movements, enabling the forearm to bend and straighten relative to the upper arm. The structure of the joint provides stability and allows for a wide range of motion in these two primary directions.
Anatomically: pivotal hinge jointStructurally: synovial jointFunctionally: uniaxial jointThe knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella. It is the largest and most complicated joint in the human body.The knee is a mobile trocho-ginglymus (i.e. a pivotal hinge joint), which permits flexion and extension as well as a slight medial and lateral rotation.
