Arthritis
Arthritis (from Greek arthro-, joint + -itis, inflammation; plural: arthritides) is a group of conditions where there is damage caused to the joints of the body. Arthritis is the leading cause of disability in people over the age of 65.
There are many forms of arthritis, each of which has a different cause. Rheumatoid arthritis and psoriatic arthritis are autoimmune diseases in which the body is attacking itself. Septic arthritis is caused by joint infection. Gouty arthritis is caused by deposition of uric acid crystals in the joint that results in subsequent inflammation. Additionally, there is a less common form of gout that is caused by the formation of needle shaped crystals of calcium pyrophosphate. This form of gout is known as pseudogout. The most common form of arthritis, osteoarthritis is also known as degenerative joint disease and occurs following trauma to the joint, following an infection of the joint or simply as a result of aging. There is emerging evidence that abnormal anatomy may contribute to early development of osteoarthritis.

History and physical examination
All arthritides feature pain. Patterns of pain differ among the arthritides and the location. Osteoarthritis is classically worse at night or following rest. Rheumatoid arthritis is generally worse in the morning; in the early stages, patients often do not have symptoms following their morning shower. In elderly people and children, pain may not be the main feature, and the patient simply moves less (elderly) or refuses to use the affected limb (children).
Elements of the history of the pain (onset, number of joints and which involved, duration, aggravating and relieving factors) all guide diagnosis. Physical examination typically confirms diagnosis. Radiographs are often used to follow progression or assess severity in a more quantitative manner.
Blood tests and X-rays of the affected joints often are performed to make the diagnosis.
Screening blood tests may be indicated if certain arthritides are suspected. This may include: rheumatoid factor, antinuclear factor (ANF), extractable nuclear antigen and specific antibodies.
Many people associate cracking joints with arthritis; however, these have never been associated with one another. A joint is an area where two or more bones meet. This area is surrounded by joint fluid to protect the bones from rubbing against each other. When a joint is cracking, the fluid is pushed out and the "cracking" sound is the result of a high pressure of fluid. Rheumatoid arthritis is what happens when there is a loss of fluid in the joints causing damage to the lining of the joint itself. There is no evidence to support that cracking your knuckles causes such damage.[1]

Treatment
Treatment options vary depending on the type of arthritis and include physical and occupational therapy, medications (symptomatic or targeted at the disease process causing the arthritis), and as a last resort, arthroplasty. Although prosthetic joint replacement is a treatment of last resort, it is generally very effective and more than 90% of patients are very satisfied.
History
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. 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. Around 500 BC willow bark gained popularity when it was discovered to help relieve some of the aches and pains of arthritis. It wasn't until more than 2,000 years later, in the early 1820s, that European scientists began to scientifically study the chemical compound in willow bark that alleviated the arthritis symptoms. They discovered the compound was salicin. When they isolated salicin, however, they found it was very noxious to the stomach. Almost 80 years later, in 1897, an employee of Bayer Company -- then a dye production company -- named Felix Hoffman discovered how to isolate the compound and make it less irritating to the stomach. Hoffman was attempting to make the drug in order to help his father, who was suffering from arthritis. In 1899, Bayer Company trademarked Hoffman's discovery under the name "Aspirin." Today it is believed that over a trillion tablets of aspirin have been sold worldwide.
