A chronic disorder characterized by softening and disintegration of articular cartilage, with reactive phenomena such as vascular congestion and osteoblastic activity in the subarticular bone, new growth of cartilage and bone (osteophytes) at the joint margins, and capsular fibrosis.

Birefringence, or double refraction, is the splitting of a ray of light into two rays when it passes through certain types of material, such as calcitecrystals. The two rays, called the ordinary ray and the extraordinary ray, travel at different speeds. Thus the material has two distinct indices of refraction, as measured from different directions.
If split ray of light is rotated clockwise is classified as positive birefringent.
If counterclockwise rotation is classifed as negatively birefringent
