The knee has a number of functions
1) Supports body in upright position without muscles having to work
2) Helps in lowering and raising body eg sitting, climbing and squatting
3) Allows rotation/twisting of leg to place and position foot
4) Makes walking more efficient
5) Acts with ankle joint as a strong forward propeller of the body
6) Provides stability of the leg
7) Acts as a shock absorber
The knee joint is responsible for a number of things
1) It holds the body upright
2) It helps the body to move up and down eg sitting down, climbing and squatting
3) allows and controls leg movement
4) Reduces energy expenditure when walking
5)It works with the ankle to propel the body forwards
6) It is a really important structure for providing stability, balance and proprocieption
7) It works as a shock absorber
the knee joints are made to fit so that humans can stand up straight and walk upright
diarthrosis
The Costochondral Joint is an immovable Cartilaginous - Synchodrosis (structural classification) joint that articulates the ribs with the coastal cartilage.It's functional classification is; Synarthrosis - a type of joint permitting no movement at all.
The three functional articulations are synarthrosis which is an immovable join and example would be a suture, amphiarthrosis a slightly immovable joint an example is the symphysis, and last the diarthrosis a freely movable joint such as the elbow or knee joint.
Costochondral joint ( Costo- = Rib, Chondro- = Cartilage) - these joints 'articulate' the ribs with the costal cartilage of the thoracic wall. However, there is no movement between the two.The Structural Classification for this joint is; Cartilaginous (Synchodrosis).The Functional Classification for this joint is; Synarthrosis.
The knee is a hinge joint.
It is not a separate joint it is your hip joint, the hip joint is a ball & socket joint!!!
pivotal hinge joint or synovial diarthrodial biaxial joint

Structural classification- how the bones are connected (fibrous joint, cartilaginous joint, synovial joint). Functional classfication- synarthrosis (little or no mobility); sutures of the skull amphiarthrosis (slight mobility); vertebrae diarthrosis (variety of mobility/movement); shoulder, hip, elbow, knee

The knee is a hinge joint.
The knee joint is located in the leg at the knee. It is a type of hinge joint.
knee
diarthrosis - all synovial joints are freely moveable
It is not a separate joint it is your hip joint, the hip joint is a ball & socket joint!!!
The largest hinge joint would be the knee. But the knee is considered a modified hinge joint because of its movement.
It can make the joint unstable.
