The kneecap sits at the front of the knee. It protects the knee joint. It is also important for knee movements. When you bend and stretch the knee, the kneecap slides along the femur. Firm tissue connects the kneecap to the muscle at the front of the thigh and to the tibia.

If bone tissue has died off, it can be painful. You may also no longer be able to move the affected area properly. The tissue around the affected bones may be swollen.

Bone tissue can die off if does not get a good supply of blood. If bone tissue has died off, the affected bone may become misshapen. The bone may also then stop growing as well.
