Step 1

This is incorrect because the knee joint is formed by the articulation of the tibia with the femur, not the fibula. The fibula does not form a joint with the patella, nor does it form a knee joint. Show more…

Key Concepts

Cartilage

Cartilage is a specialized connective tissue that is avascular, meaning it does not have its own blood supply. This absence of blood vessels requires the tissue to rely on the diffusion of nutrients and oxygen from the surrounding fluids and tissues to sustain the chondrocytes embedded within it.

Oxygen Diffusion in Avascular Tissues

In tissues lacking direct vascularization, such as cartilage, the transport of oxygen and other essential nutrients occurs through diffusion. This process is less efficient compared to direct blood supply, influencing the metabolic activity and repair capacity of the tissue.
