Although the exact causes of rheumatoid arthritis are yet to be identified, autoimmunity is said to be a major contributor to the progression of the disease. It is therefore that some people consider this condition as an autoimmune disorder. Autoimmune disorder occurs when the immune system mistakenly identifies the body’s own tissue as foreign and goes ahead to attack it. Another risk factor for this disorder is genetics. There are likely genetic variations that can cause this condition. This disorder has often been reported in multiple members of the same family.
Age is another probable cause for this disorder. Although no age is immune to this condition, the onset is often in people aged between 40 and 50. Your cartilage becomes more fragile as you age and therefore you are more likely to develop this disease as you approach your 40s or 50s. You should remember that apart from the joints, this disease can also lead to the destruction of the articular cartilage as well as the ankylosis of the joints.
Since rheumatoid arthritis is a chronic and systematic disorder that affects the joints leading to an inflammatory synovistis, an injury to the joint can aggravate the condition. A joint damage can cause irregularities in the normal smooth surface of a joint.
An example of an injury that can lead to this disorder is tibial plateau fracture. This is where the broken area of the bone enters the cartilage of the knee joint. Since joint damage is partly dependent on the number of load that the joint has to support, excess weight can heighten your chances of developing this condition.
