SYNOVIAL FLUID

Rheumatology

SYNOVIAL FLUID

1. Type A cells of the synovial membrane are phagocytic, whereas type B cells probably synthesize hyaluronic acid.

2. Chondrocytes make the cartilage.

3. Cartilage is avascular and depends on the synovial fluid for nutrients.

4. The chondrocytes can produce only a limited amount of collagen, so only slight damage is repairable.

5. Joint fluid is categorized based on the inflammatory response (WBC/mm3).

6. Frank blood (hemorrhagic joint) can be caused by trauma, bleeding diathesis, tumor, and pigmented villonodular synovitis (PVNS).
