Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints. However, it can also cause systemic complications, such as rheumatoid myopathy, which is a rare but serious condition that can lead to muscle weakness, wasting, and fatigue.
When rheumatoid arthritis affects the knee joint, it can cause severe pain, stiffness, and swelling. Over time, this can lead to damage to the joint and surrounding tissues, which can further exacerbate symptoms and potentially lead to rheumatoid myopathy.
One of the first signs of rheumatoid myopathy is often weakness in the muscles of the hips and thighs. This can make it difficult to stand up from a seated position, climb stairs, or even walk short distances. As the condition progresses, the weakness can spread to other areas of the body, such as the arms, shoulders, and neck.
In addition to muscle weakness, rheumatoid myopathy can also cause muscle wasting, which is a loss of muscle mass and strength. This can further exacerbate the weakness and fatigue associated with the condition.
Overall, rheumatoid myopathy is a serious complication of rheumatoid arthritis that can significantly impact quality of life. However, with prompt diagnosis and appropriate treatment, many people with this condition are able to manage their symptoms and maintain their mobility and independence.
