• Joint is basically a junction between two bones. These bones are held together by muscles and ligaments. Due to their proper working bones move with ease and causes no pain in junction point.
• Then the bones are covered by cartilage to protect them from rubbing to each other. This is a scientific fact that cartilages are the lubricating factor that helps bone to work smoothly without any friction.
• After that comes the synovial fluid. Synovial fluid nourishes the joint and the cartilage.
• When you have arthritis the synovial fluid and cartilage starts to wear out. Due to this wear and tear of synovial fluid the bones starts rubbing to each other.
• Along with that sometimes lack of synovial fluid, infection in the cartilage, or the combination of all can lead to arthritis.
