Osteoarthritis (OA) is often referred to as ‘degenerative joint disease’ that usually develops slowly over a period of years. It is a very common disease – 6% of adults aged 30 years old and older have frequent knee pain. Over time, the cartilage on the surface of the joint becomes damaged and begins to wear away. This is a source of pain and stiffness in the joint.1
If you suffer from arthritis you will be all too familiar with the range of symptoms that it causes and their effect upon your life.
- Normal cartilage: Provides a smooth surface allowing bones to move easily across each other.
- Synovial fluid: Lubricates and provides shock absorption during activity due to a high concentration of hyaluronic acid (HA).
- Normal bone: Provides strength and support for the body’s tissues.
- Eroded cartilage: If completely worn away, bones may scrape painfully against each other.
- OA synovial fluid: The osteoarthritis disease leads to a poor quality of HA production.
- OA bone: Bony spur growths (osteophytes).
You may suffer from OA if you have any of these symptoms:
- Stiffness in the morning
- Pain when you move
- Pain even when you are not active
- A crackling sound or a grating feeling when you walk
- Red and swollen skin
