Rheumatoid arthritis (RA) is a chronic inflammatory condition that notably impacts various joints, including the knees. It’s an autoimmune disease causing the body to mistakenly attack its own cells. RA often leads to joint pain, swelling, and stiffness, with the knee being a common site of affliction.
Symptoms of RA in the knee can include warmth around the joint, stiffness or locking, especially in cold weather or during the morning, and weakness or instability when weight is put on the joint. These symptoms can hinder movement and significantly affect daily activities.
Diagnosis of RA involves a thorough medical examination, blood work, and imaging tests to assess the extent of joint damage. About 70% to 80% of people with RA have Rheumatoid factor (RF) present. Other diagnostic indicators include high levels of erythrocyte sedimentation rate (ESR), which signify inflammation, and antibodies to a chemical called CCP.
Treatment for RA in the knee encompasses a combination of medication, home remedies, and in some cases, surgery. The goal of treatment is to manage pain, reduce inflammation, and improve joint function. Medications can include anti-inflammatory drugs and disease-modifying antirheumatic drugs (DMARDs). Lifestyle changes and home remedies, like regular exercise and heat/cold therapy, can also provide relief.
In the United States, rheumatoid arthritis is a prevalent condition, affecting over 1.3 million people. It tends to initially affect smaller joints and can progressively involve larger joints like the wrists and knees. In up to 30% of RA patients, the knee joint is impacted by this inflammatory condition.
