Osteoarthritis And Rheumatoid Arthritis

There are several different types of arthritis. Osteoarthritis and rheumatoid arthritis are two of the most common forms. Although the symptoms of these two types of arthritis can be similar, it's very important to distinguish between them in order to determine the proper treatment.

At the University of Michigan Health System, our experienced rheumatologists will do appropriate tests to determine which type of arthritis you have. Then we will develop an effective treatment plan and will explain your options.

Rheumatoid arthritis is an autoimmune disease, which means that the immune system malfunctions and attacks the body instead of intruders. In this case, it attacks the synovial membrane that encases and protects the joints. Rheumatoid arthritis often targets several joints at one time. The symptoms of rheumatoid arthritis include:

Participants: A total of 8059 patients (>/=18 years old) with osteoarthritis (OA) or rheumatoid arthritis (RA) were enrolled in the study, and 7968 received at least 1 dose of study drug. A total of 4573 patients (57%) received treatment for 6 months.

Cartilage damage is a key feature of degenerative joint disorders-primarily osteoarthritis (OA)-and chronic inflammatory joint diseases, such as rheumatoid arthritis (RA). Substantial progress has been made towards understanding the mechanisms that lead to degradation of the cartilage matrix in either condition, which ultimately results in the progressive remodelling of affected joints. The available data have shown that the molecular steps in cartilage matrix breakdown overlap in OA and RA. However, they have also, to a great extent, changed our view of the roles of cartilage in the pathogenesis of these disorders. In OA, cartilage loss occurs as part of a complex programme that resembles aspects of embryonic bone formation through endochondral ossification. In RA, early cartilage damage is a key trigger of cellular reactions in the synovium. In a proposed model of RA as a site-specific manifestation of a systemic autoimmune disorder, early cartilage damage in the context of immune activation leads to a specific cellular response within articular joints that could explain not only the organ specificity of RA, but also the chronic nature and perpetuation of the disease.

You likely know that arthritis is a broad term that refers to inflammation of the joints. However, it may surprise you to learn that it encompasses more than 100 different conditions that affect the joints themselves and the bones and tissues around them.

Osteoarthritis is the most common type of arthritis, affecting 528 million people worldwide. It happens when cartilage, which is the rubbery connective tissue covering the ends of bones in your joints, breaks down.

Pain while using the joint, stiffness (especially after a period of rest), swelling, reduced flexibility and hearing the joint click or pop are the most common symptoms. Osteoarthritis can affect any joint but frequently strikes the hands, hips, knees, neck and lower back.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disorder that impacts 18 million people around the globe, affecting nearly three times as many women as men. It occurs when the immune system mistakes certain healthy cells in the body as invaders and goes on attack. In RA, the immune system attacks the synovium, which is the tissue surrounding a joint that produces fluids to help it move smoothly.

Like other forms of arthritis, PsA causes pain, stiffness, swelling and a decline in range of motion. But PsA can also result in silver or gray scaly spots on the scalp, elbows, knees and lower spine, as well as nail depressions or detached fingernails or toenails.

Hip arthritis is deterioration of the cartilage of the hip joint. The hip is a ball-and-socket joint with the ball at the top of the thighbone (the femoral head). The ball is separated from the socket (the acetabulum) by cartilage. The cartilage acts as a slippery coating between the ball and the socket that allows the ball to glide and rotate smoothly when the leg moves. The labrum, a strong cartilage that lines the outer rim of the socket, provides stability.

Osteoarthritis is a degenerative joint disease, which means it causes gradual damage to the joint. It is the most common form of hip arthritis and can affect other joints. Hip osteoarthritis is typically caused by wear and tear related to aging and worsens over time. The breakdown of cartilage leads to pain and inflammation.

Rheumatoid arthritis (RA) is a disease resulting from the immune system attacking healthy tissue in the joints, including the hip. It causes inflammation of the synovial membrane, the capsule surrounding the hip joint. Inflammatory cells release substances that break down hip cartilage over time. RA typically affects smaller joints such as the wrist and fingers first, and may not be noticeable in the hip until it causes symptoms.

Psoriatic arthritis is a type of arthritis that can develop in people with psoriasis, an autoimmune skin condition that can also cause inflammation in the joints, including the hip. Over time, untreated inflammation can lead to joint damage. Psoriatic arthritis of the hip is a chronic condition. It can develop before or after the telltale skin symptoms of psoriasis develop.

Injury or trauma to the hip, such as hip fracture, may lead to development of arthritis later in life. Trauma such as falls, sports injuries and car accidents can damage the cartilage. While the injury itself may heal, the cartilage damage and any changes in the hip joint alignment or anatomy can lead to arthritis years later.

Avascular necrosis happens when a bone loses its blood supply and starts to collapse. In the hip, avascular necrosis may develop in the femoral head (the ball part of the hip joint). As the bone tissue dies, the femoral collapses and loses its shape, which eventually leads to severe hip arthritis.

As cartilage continues to wear down, the bones eventually rub against each other, which can cause severe joint pain, stiffness, and swelling. Although osteoarthritis can affect any joint, it frequently affects joints in the hands, neck, knees, and hips.

Rheumatoid arthritis is caused by the immune system attacking the synovial membrane. The immune system mistakes the synovial membrane for a foreign invader, attacking it as if it were an infection or virus. The cause behind this mistaken autoimmune attack is unknown.

The difference between osteoarthritis (OA) and rheumatoid arthritis (RA) is in the way these diseases harm the body. While OA is a degenerative disease caused by a physical breakdown of the cartilage, and eventually the bones, RA is an autoimmune disease caused by a reaction in the immune system.

A person who has rheumatoid arthritis may experience fatigue, malaise, and depression, preceding other symptoms by weeks to months. These are common symptoms of systemic diseases, as critical body systems, like the respiratory and cardiovascular systems, are under attack. These systems have key responsibilities in the body, and any damage to these systems can throw neurological, physiological, and physical functions off track.

Osteoarthritis manifests differently around the body. Because this disease attacks the cartilage between joints, and not the bodily systems (like RA), symptoms are typically felt around the joints. Severe joint pain, stiffness and swelling are common, along with the following symptoms:

If our rheumatology doctor, Dr. Maria Farooq, suspects rheumatoid arthritis, she will assess the affected joints to determine whether they are swollen, red, or warm, as these signs are indicative of RA. This physical exam may be followed by any of the following tests:

Arthritis is inflammation of one or more of your joints. Pain, swelling, and stiffness are the primary symptoms of arthritis. Any joint in the body may be affected by the disease, but it is particularly common in the knee.

Osteoarthritis is the most common form of arthritis in the knee. It is a degenerative, wear-and-tear type of arthritis that occurs most often in people 50 years of age and older, although it may occur in younger people, too.

In osteoarthritis, the cartilage in the knee joint gradually wears away. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone and produce painful bone spurs.

Rheumatoid arthritis is a chronic disease that attacks multiple joints throughout the body, including the knee joint. It is symmetrical, meaning that it usually affects the same joint on both sides of the body.

Rheumatoid arthritis is an autoimmune disease. This means that the immune system attacks its own tissues. The immune system damages normal tissue (such as cartilage and ligaments) and softens the bone.

Posttraumatic arthritis is form of arthritis that develops after an injury to the knee. For example, a broken bone may damage the joint surface and lead to arthritis years after the injury. Meniscal tears and ligament injuries can cause instability and additional wear on the knee joint which, over time, can result in arthritis. e24fc04721
