What is the Difference Between Rheumatoid Arthritis and Osteoarthritis?

Many people use the term arthritis interchangeably to describe the symptoms and causes of progressive joint deterioration and pain. However, there are several different forms of arthritis, which result in inflammation of the joints and results from a number of causes depending on the type. The most common form is osteoarthritis (OA), and is generally caused by aging and the resulting wear and tear on the joints, most commonly those of the knees and hips. It can also result from a traumatic impact suffered from a car accident, a fall, or from an old sports injury. Arthritis treatment offered by Los Angeles rheumatologist Dr. Susan Baker can make a major difference in everyday life and comfort.

Another common form, known as rheumatoid arthritis (RA), is actually an autoimmune disorder which occurs when the body’s own immune system targets healthy tissue. Both can lead to cartilage loss and permanent joint damage, which can cause chronic pain and affect proper function and mobility of the joint.

Osteoarthritis Causes, Symptoms, and Risk Factors

The bones in the various joints throughout the body are lined with a layer of cartilage, which prevents friction and allows the bones to glide freely to facilitate the motions that allow us to bend the knees, raise our arms above our shoulders, and sit and stand without experiencing pain and stiffness. Over time, the cartilage can wear out, leaving the ends of the bones exposed, which can result in pain and permanent damage to the joint if left untreated.

Osteoarthritis is the most common form of arthritis in Los Angeles. The most common symptoms are:

RA Causes, Symptoms, and Risk Factors

Although Beverly Hills rheumatoid arthritis affects the joints and can have some overlapping symptoms with osteoarthritis, rheumatoid arthritis is caused by a malfunction in the immune system that causes it to mistake healthy cells and tissue for foreign invaders, and setting off an immune response that attacks the healthy cells. The main symptoms of rheumatoid arthritis are:

RA tends to begin in the smaller joints of the fingers and toes, and then progress to the larger joints. Unlike OA it affects multiple joints at once on both sides of the body. LA rheumatoid arthritis can affect other organs and tissue in the body in addition to the joints and can lead to permanent joint damage and deformity over time. Like all medical conditions, rheumatoid arthritis affects everyone differently, and the range and severity of symptoms vary from patient to patient.

Causes and Risk Factors for Rheumatic Disease

A direct cause for the onset of rheumatoid arthritis is unclear, but genetics are believed to play a role in the development and progression of inflammation that triggers the adverse immune response responsible for RA-related joint degeneration.
