What are the Different Forms of Arthritis?

With over 100 different variations and related conditions, arthritis affects as many as 350 million people around the world; an estimated 40 million in the United States alone. Arthritis is the technical term for joint inflammation, but it is also used as an umbrella term for a wide range of rheumatological conditions. If you suspect that you or a loved one may be suffering from joint inflammation, do not wait to contact a Beverly Hills rheumatologist for expert arthritis treatment and management.

Most Common Forms of Arthritis

General Arthritis

Inflammation of the joints that leads to pain and stiffness. Chronic inflammation can potentially result in permanent tissue damage. General arthritis can develop as a result of an injury or strain, as well as basic wear and tear over time.


This form of arthritis is not caused by an immune system disorder, but rather by the deterioration of the cartilage that protects the joints and keeps them functioning properly. The most common symptoms include pain, swelling, and stiffness in the affected joints. Osteoarthritis can result from an injury, wear and tear, or genetic predisposition to the condition.

Rheumatoid Arthritis (RA)

RA is an autoimmune disorder that causes chronic inflammation in the joints of the hands and feet. The swelling in the lining of the joints associated with RA causes painful swelling and can lead to permanent joint damage and deterioration over time.

Psoriatic Arthritis

Psoriasis is a skin condition that results in an itchy, dry rash and silvery scales on the surface of the skin due to an overproduction of skin cells. In some people with psoriasis, the immune system begins to attack healthy tissue and cells, leading to inflammation and painful swelling and stiffness in the joints.

Inflammatory Bowel Arthritis (Chron’s Disease and Ulcerative Colitis Arthritis)

Inflammatory bowel disease (IBD) encompasses both Chron’s disease and ulcerative colitis. IBD is an autoimmune disorder where the immune system targets healthy tissue, leading to pain, inflammation, and swelling. Chron’s disease can affect any portion of the digestive tract, while ulcerative colitis typically affects the colon and small intestine. IBD-related arthritis usually affects the joints of the wrists, elbows, ankles, knees, and hips.

Reactive Arthritis

This form of arthritis develops as a secondary side effect of an infection in another part of the body, most commonly in the urinary tract, intestines, or genitals. Symptoms include pain and swelling from inflammation in the joints in the ankles and knees, as well as potential swelling of the fingers and toes.
