It is a complex disease of the entire joint affecting all tissues: cartilage, synovial membranes, muscles... causing pain, stiffness, and limitations of activity.

Osteoarthritis is the most common joint disease in developed countries.
It corresponds to a destruction of the cartilage of a joint, leading to pain. Osteoarthritis is often associated with the elderly; it is true that with age, tissue degeneration is accentuated, and that there are more patients in the elderly than the young.

However, even if you are young, you are not completely safe: indeed, osteoarthritis can also affect people 30 years of age or younger, due to a malformation, a sports injury or other factors.

Finally, osteoarthritis can be associated with metabolic syndrome; it then affects patients with obesity, hypercholesterolaemia or type 2 diabetes.
