Osteoarthritis (OA) is the most prevalent type of arthritis. It occurs when the smooth, slippery cartilage that coats the endings of bones begins to deteriorate at a joint (where two bones meet). This wear and tear can increase friction, bone spurring, pain, and stiffness.

Though OA can develop at any joint, it is most common in the hands, spine, knees, hips, and feet.

This article will outline the most common causes, symptoms, and treatments for osteoarthritis.

When two bones meet, a joint forms. A smooth, slippery coatingcalled cartilagecoats the endings of bones and helps one glide against the other.

Several hallmark symptoms are typically seen with osteoarthritis. Some of the most common are:

In addition, several specific signs may present depending on which joint is affected. This includes:

Many people hear that a lifetime of physical activity or exercise can develop osteoarthritis in their bones and joints. However, a recent review dispelled this myth and found moderate physical activity does not cause OA to develop. Instead, it identified several other potential causes, including:

Many OA risk factors may potentially elevate your likelihood of developing osteoarthritis. These include:

The research establishing these risk factors is still in progress. Speak to a healthcare provider about your specific situation and any personal risk factors that may need modifying.

Preventing osteoarthritis from progressing or becoming symptomatic may be possible if you address some of the conditions risk factors. Some strategies that may benefit you include:

There are significant differences between osteoarthritis and rheumatoid arthritis. For example:

There are significant differences between osteoarthritis and rheumatoid arthritis.

As previously mentioned, osteoarthritis occurs after wear and tear cause a bones cartilage to deteriorate at a joint. This increases friction, excessive bony buildup, and pain or soreness. OA commonly affects weight-bearing joints (like the hips or knees) and frequently occurs on only one side of the body.

Rheumatoid arthritis (RA), on the other hand, is an autoimmune disease that causes your bodys immune system to attack its joint tissue. This tissue damage frequently leads to pain, swelling, and inflammation. RA most commonly impacts smaller joints, like those in the hands or feet, and is usually seen simultaneously on both sides of the body.

To accurately diagnose osteoarthritis, a healthcare provider usually performs a comprehensive evaluation. During this process, they will examine the affected joint(s) and take a personal history of your symptoms.

They may also obtain an X-ray to provide a clear image of the joint in question. This test can show damage to your bone, bone spurring, and any loss of space within the affected joint.

Finally, they can order magnetic resonance imaging (MRI) if they suspect concurrent damage to the muscles, ligaments, tendons, or other soft tissue structures.

Depending on the severity of your arthritis symptoms, they may suggest several different treatment strategies. The most common are outlined below.

Pain relievers or non-steroidal anti-inflammatory drug (NSAID) medications are frequently recommended to help treat OA pain and inflammation. Pain-relieving creams, rubs, or sprays may also help. Occasionally, a stronger corticosteroid may need to be taken orally or injected into the joint to alleviate a severe OA aggravation.

One of the biggest lifestyle changes you can make to impact your OA symptoms is maintaining a healthy body weight. Losing excess weight can:

Staying active with an exercise program focusing on strength, flexibility, and cardiovascular fitness is another cornerstone of OA self-care. A healthcare provider can guide safe ways to begin a new fitness regimen. They may also refer you to physical therapy for more structured guidance on appropriate osteoarthritis exercise techniques.

In severe cases of OA, surgery may be necessary. This is especially true if more conservative treatments fail to relieve your symptoms.

Depending on the affected area, this may involve a joint replacement (arthroplasty) or a joint fusion (arthrodesis) procedure. Occasionally, osteotomy surgery may also be recommended. This operation involves removing a piece of bone to alleviate pressure on the arthritic portion of the joint.

In some situations, a brace can reduce some of your osteoarthritis pain.

Most commonly utilized for knee arthritis, braces can:

Similar devices may also be recommended for osteoarthritis in your fingers, wrists, ankles, or elbows. Though bracing an arthritic area will not prevent OA from advancing, it may provide short-term enhancements to your day-to-day function and diminish some of your pain.

Several other treatments may help you manage your osteoarthritis pain.

Because platelets play a role in regenerating tissue and controlling inflammation, some have recommended platelet-rich plasma (PRP) injections for OA. Unfortunately, the research on this intervention is still mixed. Currently, there is low-level evidence showing that PRP injections may provide short- and medium-term pain relief for osteoarthritis.

Stem cell therapy has also been proposed as a potential management strategy. Stem cells are thought to help regenerate cartilage and reduce inflammation levels. Unfortunately, the evidence supporting this treatment is also still mixed. Several low-quality studies found reduced evidence of osteoarthritis and diminished pain levels after receiving this treatment. More research in this area is still necessary, however.

There is currently no evidence-based treatment that reverses osteoarthritis. That said, the presence of OA on an X-ray does not necessarily mean that you will have symptoms. It is possible to have osteoarthritis and minimal to no pain.

By staying active, maintaining a healthy body weight, taking medications as prescribed, and wearing braces if recommended, you may be able to keep pain levels low while continuing with the activities you love.

Osteoarthritis usually progresses slowly and gets worse as time goes on. As the cartilage in a joint thins, friction increases with movement and triggers bone spurs. This bone adds to the irregularity of the joint surface and begins to cause inflammation, swelling, and pain.

Though these symptoms may be mild and infrequent at first, over time, the pain from severe osteoarthritis may become more intense and constant. Other factors like heavy loading of the affected joint and excessive body weight can also accelerate this process.

To remain active and maintain a healthy body weight in spite of osteoarthritis, try following these steps:

OA can cause severe pain and significantly limit overall mobility if inadequately treated. This shift to a more sedentary lifestyle may also lead to the development of other health conditions like obesity, metabolic syndrome, and diabetes.

Fortunately, many cases of osteoarthritis are effectively managed with the conservative treatments listed above. Working closely with a healthcare provider can help avoid these potential side effects and ensure a better long-term outlook.
