Osteoarthritis of the know?

Hi All,

Continue my Ergonomic ...

Now we are talking about Osteoarthritis of Knee..what is that...ok Osteoarthritis is a type of arthritis that is caused by the breakdown and eventual loss of the cartilage of one or
more joints. Cartilage is a protein substance that serves as a "cushion" between the bones of the joints. Osteoarthritis is also known as degenerative arthritis.

What causes osteoarthritis
Primary osteoarthritis is mostly related to aging. With aging, the water content of the cartilage increases, and the
protein makeup of cartilage degenerates. Eventually, cartilage begins to degenerate by flaking or forming tiny
crevasses. In advanced cases, there is a total loss of cartilage cushion between the bones of the joints. Repetitive
use of the worn joints over the years can irritate and inflame the cartilage, causing joint pain and swelling. Loss
of the cartilage cushion causes friction between the bones, leading to pain and limitation of joint mobility.
Inflammation of the cartilage can also stimulate new bone outgrowths (spurs, also referred to as osteophytes) to
form around the joints. Osteoarthritis occasionally can develop in multiple members of the same family,
implying a hereditary (genetic) basis for this condition.
