Arthritis refers to the redness and swelling of the joints. It usually develops slowly over 10 to 15 years, interfering with daily life activities. Knowing the early signs of arthritis can help you take appropriate treatment and incorporate modifications in your diet and lifestyle.

The knee joint is the largest and the most complex joint in the body. Depending on the cause, the early signs and symptoms of arthritis in the knee joint may vary amongst individuals. Typically, these include:

  • Pain while climbing stairs or walking
  • Joint stiffness after sitting for prolonged periods with bended knees
  • Difficulty in straightening the knee after getting up in the morning
  • Swelling over the knees that gets worse on walking
  • Bones in the knee joint rub against each other giving rise to the sound of creaking, clicking or snapping, or grinding
  • Many people with arthritis experience increased joint pain during rainy weather

What causes arthritis in the knee?

All kinds of arthritis are characterized by wear and tear of the cartilage followed by a reduction in the joint space.

Three types of arthritis affect the knee mainly:

  • Osteoarthritis (OA): This type of arthritis is also known as degenerative joint disease, primary OA, wear-and-tear arthritis, or age-related arthritis. It is a leading cause of disability in the United States and worldwide. Though more common in older people, it can affect young people, including children as well.
  • Rheumatoid arthritis (RA): This is an autoimmune and chronic kind of arthritis that affects multiple joints in the body. Autoimmune means the body attacks its own healthy cells. Over time, the inflammation causes degeneration of cartilage along with the softening of the bone.
  • Posttraumatic arthritis: This kind of arthritis is preceded by a traumatic event that impacts the knee joint. The injury damages the knee and arthritis develops after a few to several years in the knee joint.

Factors that increase your risk for developing osteoarthritis include:
