Basics of Osteoarthritis


Arthritis is generally defined as an inflammation of the joints. The most common type of arthritis is osteoarthritis, otherwise referred to as wear and tear arthritis. This happens when the joint cartilage breaks down, and this can happen in any body joint. Joints that bear weight, like at the knees, hips, and spine, often develop this. This condition can also impact the neck, large toe, fingers and thumb. Osteoarthritis, also known as OA, generally will not affect other joints unless they were injured or if the joints were overly stressed.

In normal bones, cartilage is the materials with a rubbery texture that encases the ends. Its primary purpose is to absorb shock and reduce friction in joints. When it is pressed together or compressed, normal cartilage changes shape and absorbs the shock.

When osteoarthritis occurs, the joint cartilage loses its elasticity and stiffens, increasing the risk of damage. As time passes, this cartilage can wear away, thus reducing its capability to absorb shock. As the deterioration of the cartilage progresses, it causes ligaments and tendons to stretch, resulting in pain. If this degeneration continues, the ends of the bones will rub against each other.
