Early Symptoms of Osteoarthritis

Symptoms of osteoarthritis vary greatly from patient to patient and they depend on the severity of cartilage loss and the joint(s) affected. Many people with osteoarthritis have no symptoms or minimal symptoms while some suffer extreme loss of function of the joints involved.

Osteoarthritis in any area of the hand can lead to symptoms of inflammation including

  • stiffness,
  • redness,
  • warmth,
  • swelling, and
  • pain as well as loss of grip, dexterity, and flexibility.
  • This can cause great pain with handshaking and other activity.

What is osteoarthritis?

Osteoarthritis is a form of arthritis that features the breakdown and eventual loss of the cartilage of one or more joints. Cartilage is a protein substance that serves as a "cushion" between the bones of the joints. Among the over 100 different types of arthritis conditions, osteoarthritis is the most common. Osteoarthritis occurs more frequently as we age. Before age 45, osteoarthritis occurs more frequently in males. After 55 years of age, it occurs more frequently in females. In the United States, all races appear equally affected. A higher incidence of osteoarthritis exists in the Japanese population, while South-African blacks, East Indians, and Southern Chinese have lower rates. Osteoarthritis is abbreviated as OA or referred to as degenerative arthritis or degenerative joint disease (DJD).

Osteoarthritis commonly affects the hands, feet, spine, and large weight-bearing joints, such as the hips and knees. Osteoarthritis usually has no known cause and is referred to as primary osteoarthritis. When the cause of the osteoarthritis is known, the condition is referred to as secondary osteoarthritis.

What is the difference between osteoarthritis and rheumatoid arthritis?

Osteoarthritis is a disease of cartilage. It is not a systemic disease. It is not an autoimmune disease. Rheumatoid arthritis is an autoimmune disease, therefore, it features a misdirected immune system that attacks body tissues (particularly the joint lining tissue called synovium). Rheumatoid arthritis is also a systemic disease. Therefore, rheumatoid arthritis can attack tissues throughout the body beyond affected joints, including the lungs, eyes, and skin.
