Arthritis is a general medical term used to describe a disorder that affects joints.[2] Symptoms generally include joint pain and stiffness.[2] Other symptoms may include redness, warmth, swelling, and decreased range of motion of the affected joints.[2][3] In certain types of arthritis, other organs such as the skin are also affected.[5] Onset can be gradual or sudden.[3]
There are several types of arthritis.[2][8][9] The most common forms are osteoarthritis (most commonly seen in weightbearing joints) and rheumatoid arthritis.[2] Osteoarthritis usually occurs as an individual ages and often affects the hips, knees, shoulders, and fingers.[5] Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet.[5] Other types of arthritis include gout, lupus, and septic arthritis.[3][5] These are inflammatory based types of rheumatic disease.[2]
Early treatment for arthritis commonly includes resting the affected joint and conservative measures such as heating or icing.[5] Weight loss and exercise may also be useful to reduce the force across a weightbearing joint.[5] Medication intervention for symptoms depends on the form of arthritis.[5] These may include anti-inflammatory medications such as ibuprofen and paracetamol (acetaminophen). With severe cases of arthritis, joint replacement surgery may be necessary.[5]
Osteoarthritis is the most common form of arthritis affecting more than 3.8% of people, while rheumatoid arthritis is the second most common affecting about 0.24% of people.[10] In Australia about 15% of people are affected by arthritis,[11] while in the United States more than 20% have a type of arthritis.[3] Overall arthritis becomes more common with age.[2] Arthritis is a common reason people are unable to carry out their work and can result in decreased ability to complete activities of daily living.[2][3] The term arthritis is derived from arthr- (meaning 'joint') and -itis (meaning 'inflammation').[12][13]
