Orthopaedic Surgery/Articular Tissues

Articular tissues

  1. Definition and Structure:
    • Articular cartilage is a specialized connective tissue found in synovial joints.
    • It consists of hyaline cartilage with a dense extracellular matrix (ECM).
    • The ECM primarily contains collagen, proteoglycans, and glycoproteins.
    • Chondrocytes, specialized cells within the cartilage, are scattered throughout.
    • Remarkably, articular cartilage lacks blood vessels, nerves, and lymphatic tissue.
  2. Function:
    • The main role of articular cartilage is to provide an optimal surface for joint movement.
    • It prevents friction between bones during articulation.
    • Additionally, it facilitates the transmission of loads to the underlying bone.
  3. Clinical Importance:
    • Articular cartilage injuries can lead to significant musculoskeletal dysfunction.
    • Unfortunately, cartilage has limited healing ability, emphasizing the need for preservation.
