Arthritis rheumatoid

Arthritis knee is a condition that describes pain, stiffness or tenderness along the joints of the knees as a result of physical activities, associated with arthritis. There are different types of arthritis affecting the knees, the most common of them being osteoarthritis. Osteoarthritis is caused by wearing away of the cartilage of the joint and it is often present with elderly people. In contrast, in rheumatoid arthritis, which can also affect the knees, the joint becomes inflamed and this may lead to the destruction of the cartilage. Rheumatoid arthritis is a condition which affects younger people and is associated with different inherited factors. It also most often affects both knees. Post-traumatic arthritis is the third type of arthritis often affecting the knees. This can develop after an injury to the knee and very much resembles osteoarthritis. Post-traumatic arthritis is difficult to identify as it may appear years after the injury of the ligament or meniscus tear.
