A pivot joint is a type of synovial joint which only allows rotary movement around a single axis. One example is the proximal radio-ulnar joints.
The knee is a mobile trocho-ginglymus joint (a pivotal hinge joint).
The joint between the leg and the hip is the hip joint, which is a ball-and-socket joint. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation of the leg. The hip joint is supported by a network of muscles, ligaments, and tendons that help stabilize the joint during movement.
The hip joint is a ball and socket joint so it possible to move the leg around in a 360 degree circle. The knee joint is a pivotal hinge joint so it can only move backwards and forwards with slight rotation.
There is not a ball and socket joint at the knee. It is a complex hinge joint. The knee joint begins to wear out from walking and carrying most of our weight. As we age, the socket may need to be replaced. If we walked up and down the Empire State Building 10,000 times, that is how much walking we will do in a life time.
If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
A pivotal joint is a joint in the skeletal system that allows rotary movement, which is why it is also referred to as a rotary joint.
The space between skull and first vertebrae would have a pivotal joint.
The knee is not a fixed joint it is a pivotal hinge joint; they are completely different a fixed joint barely moves where as a pivotal hinge joint moves in four directions.
