Question

describe how osteoarthritis develops and forms and distinguish primary osteoarthritis from secondary arthritis

Answer 1

Osteoarthritis in which the catilage between two bones resorbs thus leading to friction between the bones.

Primary osteoarthritis is in which the Cartilage which act as a soft cushion between the bones is lost which leads to rubbing of the bones between them and thus causing primary osteoarthritis.

Secondary osteoarthiritis is the condition in which the cartilage is lost due to some external factors like injury, surgery or stress on the joint especially in the weight bearing joints like knees.
