M09.26: Juvenile arthritis in ulcerative colitis Lower leg

You have an intestinal disorder that is causing joint inflammation in your knee.

The knee joint connects the thighbone (femur) to the lower leg. The kneecap is also part of the knee joint. There are 2 bones in the lower leg. These bones are called the tibia (shinbone) and fibula. There is also a joint immediately below the knee joint between the tibia and fibula.

An inflammation in the joints can cause various symptoms. Typical is a swollen, painful joint. The skin above the joint may also be red. It may also no longer be possible to move the joint as usual.

You have ulcerative colitis. This disease involves the immune system attacking one’s own body. This results in inflammations in the intestines. The immune system may also attack the joints. So the joints may become inflamed too.

The inflammation in your joints occurred before you were 16.
