What is Synovial Fluid?

Functions of Synovial Fluid

Synovial fluid allows nearly frictionless articulation, distributes hydraulic shock, and delivers essential nutrients to avascular cartilage cells.

Fluid Reduction vs Joint Effusion

Declining hyaluronic acid density leads to joint dryness and cartilage wear. Conversely, trauma or torn meniscus triggers excessive fluid secretion (joint effusion).

Signs of Synovial Imbalance

• Dryness and clicking during first morning steps
• Tension and visible swelling around the knee cap
• Fullness behind the knee (popliteal Baker's cyst)

Frequently Asked Questions

How do hyaluronic acid injections help?

They replenish degraded joint lubrication, reducing frictional stress and mitigating pain.
