I guess this question is "what is your patella?" In which case, the answer is that the patella is the knee cap, the bone that covers the ball-and-socket joint of the tibia and fibula with the femur bone in the knee.
No, The patella or kneecap is a thick, triangular bone which articulates with the femur and covers and protects the knee joint.
Actually it's cartilages and the synovial fluid which makes the joint movements smooth.....
Hyaline cartilage covers the ends of bones in many joints. It provides a slippery surface to reduce friction during bone movement.
then the joint has no cartilage. Cartilage is a tough low friction coating that covers the bone where they form joints it has no nerves that can sense pain. However once it is gone the bone begins to rub directly against bone. Bones do feel pain when damaged. as the bone wears away at its opposing bone in the joint it begins to try and repair itself and that creates ridges or lipping that cause more pain and stiffness in the joint this process can be accompanied by inflammation leading to deformity surrounding the joint.

The Articular Capsule is a tought, flexible and fibrous capsule that covers the joint cavity. It is there to support and protect the joint.
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
