How Rheumatoid Arthritis Knee Xray Can Help You Manage Your Condition and Why You Should Try Red Light Therapy Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects the joints and other parts of the body. It can cause pain, stiffness, swelling, and reduced mobility in the affected areas. RA can also affect the immune system, making it harder to fight off infections and other diseases. One of the most common joints that are affected by RA is the knee. The knee is a complex joint that consists of bones, cartilage, ligaments, tendons, and muscles. It allows us to bend, straighten, and rotate our legs. It also supports our body weight and helps us walk, run, jump, and squat.
However, when RA attacks the knee, it can cause inflammation and damage to the joint and its surrounding structures. This can lead to symptoms such as:
Knee pain, which may be constant or intermittent, and may worsen with movement or pressure Knee stiffness, which may limit the range of motion and make it difficult to bend or straighten the leg Knee swelling, which may make the joint appear larger or warmer than usual, and may cause fluid accumulation or cyst formation
