Clinical information

Arthritis is a general term for conditions causing inflammation and degeneration of joints, resulting in joint pain and stiffness. Here's some essential clinical information:

  • Arthritis types range from those related to wear and tear of cartilage, like osteoarthritis, to those associated with inflammation resulting from an overactive immune system, like rheumatoid arthritis.
  • Symptoms of arthritis typically include joint pain, swelling, stiffness, and decreased range of motion.
  • The severity of symptoms can vary, and they may come and go. They can be mild, moderate, or severe and may stay the same for years but progress or worsen over time.
  • Risk factors for arthritis include family history, age, sex, previous joint injury, and obesity.
  • While arthritis is more common among adults aged 65 years or older, it can affect people of all ages, including children.
  • There is no cure for arthritis, but many treatment options exist to manage symptoms. Lifestyle changes, physical therapy, medication, and in some cases, surgery can help slow the progression of the disease and improve the quality of life.

Synonyms include

  • Joint inflammation
  • Joint degeneration
  • Osteoarthrosis
  • Rheumatoid disease
  • Juvenile arthritis
