Articular Cartilage Composition and Function
Quick fact
Articular cartilage is the thickest and most highly specialized type of connective tissue in the human body.
Why this is interesting
Ever wondered why your knees feel smooth when you walk? It’s thanks to a special tissue called articular cartilage that protects your joints.

Understanding Articular Cartilage Composition and Function
Articular cartilage is a thin, slick layer that covers the ends of bones in joints. It acts like a cushion, reducing friction and absorbing shocks during movement. Its unique makeup allows it to remain flexible yet strong, making it vital for smooth joint function.
A deeper explanation
The composition of articular cartilage includes collagen fibers, which provide structure and strength, and proteoglycans, which attract water and create a gel-like matrix. This hydrophilic property helps the tissue resist compression and distribute pressure evenly across the joint surface. The interaction with synovial fluid further enhances its ability to withstand mechanical stress, making it essential for maintaining mobility and preventing wear in joints.
