What is the function of articular cartilage?

Articular cartilage plays a vital role in joint health and function by reducing friction between the bones in a joint. This specialized type of cartilage covers the surface of bones at joints, allowing them to glide smoothly over one another during movement. By minimizing friction, articular cartilage helps prevent wear and tear and reduces the risk of joint damage, pain, and conditions such as osteoarthritis.

The composition of articular cartilage, which includes a gel-like matrix of proteins and water, allows it to absorb shock and distribute loads across the joint surfaces effectively. This cushioning effect is crucial during activities that involve weight-bearing and extensive movement.

Understanding the function of articular cartilage highlights the importance of maintaining joint health and can also inform approaches to injury prevention and rehabilitation strategies for conditions that affect joint mobility.
