What is Articular Cartilage?

Biological Properties of Articular Cartilage

Articular cartilage contains neither blood vessels nor nerve endings. While this ensures painless weight-bearing, it significantly impairs intrinsic tissue regeneration following wear or trauma. It depends entirely on synovial fluid diffusion.

Cartilage Degradation and Chondromalacia

Damage typically initiates as softening and superficial fissuring. Progressive erosion exposes subchondral bone, evolving into chronic osteoarthritis.

Symptoms of Cartilage Wear

• Sharp pain behind kneecap going down stairs
• Grinding or gritty sensation when flexing the joint
• Stiffness and resistance to full extension
• Joint swelling following weight-bearing activities

Frequently Asked Questions

Can articular cartilage regenerate naturally?

Spontaneous repair is very limited due to lack of vascularity. Arthroscopic chondroplasty, mosaicplasty, and regenerative therapies help restore joint function.
