What is knee swelling?
Swelling of the knee can be caused by injuries to the joint as well as many different medical conditions. Depending upon the cause, knee swelling may be painful or may not produce any other symptoms. In some cases, you may notice tenderness, warmth, difficulties with moving your knee joint, muscle weakness, or bleeding or bruising. Injuries to your knee, including sprains (damage to the stabilizing ligaments of the joint), can lead to diffuse swelling of the knee area.
