The purpose is so that your body can bend
The hip joint (iliofemoral joint) is a ball-and-socket joint that provides a wide range of movement. Its main purpose is to provide articulation for the femur bone.

The tibia, or shin bone, is not a joint.
A dislocation happens when a bone is forced out of its joint.
The hip bone and the shoulder bone its the knee bone joint
Partial displacement of a bone from its joint is a medical subluxation. Complete displacement of a bone from its joint is a dislocation.
Ligaments are soft fibrous tissue which connect bone to bone. Their primary functions in the body are to determine a joint's range of motion and to protect joints and bones.
The knee itself is made of ligaments cartilage and bone, and the kneecap is made of bone.
a bone moves when a joint doesn't.Bones are stiff, joints are bendy.
A dislocation happens when a bone is forced out of its joint.
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.
The articular cartilage are spongy cushions that absorb compression placed on the joint and keep the bone ends from being crushed. When the 2 bones rub against each other, they'll be rubbing on the cartilage not on the bone. If the bones really rub against each other, then you will have joint problems like osteoarthritis (swollen joint, pain).
