Orthopaedic Surgery/Articular Tissues
Articular tissues
- 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.
- 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.
- Clinical Importance:
- Articular cartilage injuries can lead to significant musculoskeletal dysfunction.
- Unfortunately, cartilage has limited healing ability, emphasizing the need for preservation.
