Types of Cartilage and Their Distribution in the Human Body

Fibrocartilage: Strength, Function, and Key Locations

Fibrocartilage is a specialized form of cartilage that provides strength and durability in weight-bearing and high-stress areas of the human body. Unlike hyaline and elastic cartilage, fibrocartilage is rich in collagen fibers, making it highly resilient to compression and shear forces.

Structure and Composition

Fibrocartilage contains dense networks of Type I and Type II collagen fibers, enhancing its toughness. It lacks a well-defined perichondrium, distinguishing it from other cartilage types.

Function and Role in Orthopaedics

• Shock absorption in high-load areas
• Joint stability and support
• Resistance to mechanical stress

Key Locations in the Human Body

Fibrocartilage is found in several critical regions, including:

• Intervertebral discs
• Menisci of the knee
• Pubic symphysis
• Temporomandibular joint (TMJ)

Clinical Significance

Damage to fibrocartilage structures often leads to conditions like degenerative disc disease, meniscal tears, and joint dysfunction. Proper diagnosis and management are crucial for maintaining joint function and mobility.
