The iliotibial tendon, or band, is a thick, fibrous tissue that runs from the lateral side of the pelvis to the lateral part of the knee. The iliotibial band is important in stabilizing the knee during walking or running. However, overuse can cause this fibrous tissue to become inflamed. You should be aware of these symptoms associated with iliotibial band tendonitis.
Pain
The most common symptom of iliotibial band tendonitis is a diffuse pain over the lateral part of the knee, according to the American Academy of Family Physicians (AAFP). This initial pain is described as dull and achy. However, over time this pain may localize to the bony areas of the outer knee and become more painful and sharp. Pain is made worse during physical activities such as running or during prolonged sitting. Do not hesitate to see your doctor if you are experiencing this symptoms. Iliotibial band tendonitis is easier to treat when diagnosed early.
Swelling
According to the Mayo Clinic, swelling is an associated symptom of iliotibial band tendonitis. This can occur along any point of the band; however, swelling is more profound at the lateral part of the knee. Look for an area that is red, painful and warm to the touch if you suspect you have a swollen knee. Swelling is usually exacerbated with physical activity, or if you are sitting or standing for prolonged periods of time. This occurs because gravity causes blood and other fluid to collect in the area of swelling. You should elevate your knee above the level of your heart when possible to reduce swelling. In more severe cases, you can try taking over-the-counter anti-inflammatory medications as directed.
Tenderness
Tenderness at the lateral part of the knee joint is a common symptom of iliotibial band tendonitis. The outer area of your knee may be painful when touched, especially after a bout of physical activity. Your doctor will likely apply firm pressure to your lateral knee to check for this symptom of iliotibial band syndrome.
