Arthritis (from Greek arthro-, joint + -itis, inflammation; plural: arthritides) is a group of conditions involving damage to the joints of the body.

There are over 100 different forms of arthritis. The most common form, osteoarthritis (degenerative joint disease) is a result of trauma to the joint, infection of the joint, or age. Other arthritis forms are rheumatoid arthritis, psoriatic arthritis, and autoimmune diseases in which the body attacks itself. Septic arthritis is caused by joint infection.

The major complaint by individuals who have arthritis is pain. Pain is often a constant and daily feature of the disease. The pain may be localized to the back, neck, hip, knee or feet. The pain from arthritis occurs due to inflammation that occurs around the joint, damage to the joint from disease, daily wear and tear of joint, muscles strains caused by forceful movements against stiff, painful joints and fatigue. The most important factor in treatment is to understand the disorder and find ways to overcome the obstacles which prevent physical exercise.

Epidemiology

Arthritis is a disease of elderly, but children can also be affected by the disease. More than 70% of individuals in North America affected by arthritis are over the age of 65. Arthritis is more common in women than men at all ages and affects all races, ethnic groups and cultures. An estimated 46 million individuals in USA have arthritis and the numbers continue to increase each year. Close to one million individuals are admitted to hospitals each year because of their arthritis.

History and physical examination

All arthritides feature pain. Pain patterns may differ depending on the arthritides and the location. Rheumatoid arthritis is generally worse in the morning and associated with stiffness; in the early stages, patients often have no symptoms after a morning shower. In the aged and children, pain might not be the main presenting feature; the aged patient simply moves less, the infantile patient refuses to use the affected limb.

Elements of the history of the disorder guide diagnosis. Important features are speed and time of onset, pattern of joint involvement, symmetry of symptoms, early morning stiffness, tenderness, gelling or locking with inactivity, aggravating and relieving factors, and other systemic symptoms. Physical examination may confirm the diagnosis, or may indicate systemic disease. Radiographs are often used to follow progression or assess severity in a more quantitative manner.

While evidence of primary ankle (kaki) osteoarthritis has been discovered in dinosaurs, the first known traces of human arthritis date back as far as 4500 BC. In early reports, arthritis was frequently referred to as the most common ailment of prehistoric peoples. It was noted in skeletal remains of Native Americans found in Tennessee and parts of what is now Olathe, Kansas. Evidence of arthritis has been found throughout history, from Ötzi, a mummy (circa 3000 BC) found along the border of modern Italy and Austria, to the Egyptian mummies circa 2590 BC.

Disability

Arthritis is the most common cause of disability in the USA. More than 20 million individuals with arthritis have severe limitations in function on a daily basis. Absenteeism and frequent visits to the physician are common in individuals who have arthritis. Arthritis makes it very difficult for individuals to be physically active and soon become home bound.

It is estimated that the total cost of arthritis cases is close to $100 billion of which nearly 50 % accounts from lost earnings. Each year, arthritis results in nearly 1 million hospitalizations and close to 45 million outpatient visits to health care centers.

Arthritis makes it very difficult for the individual to remain physically active. Many individuals who have arthritis also suffer from obesity, high cholesterol or have heart disease. Individuals with arthritis also become depressed and have fear of worsening symptoms.
