&Iliotibial band Syndrome=The ITB is a dense fibrous band of tissue that originates from the anterior superior iliac spine region and extends down the lateral portion of the thigh to the knee. The ITB has insertions on the lateral tibial condyle (ie, the Gerdy tubercle) and the distal portion of the femur. Iliotibial band syndrome (ITBS) is the result of inflammation and irritation of the distal portion of the iliotibial tendon as it rubs against the lateral femoral condyle, or less commonly, the greater tuberosity. The patient typically reports pain at the lateral aspect of the knee; however, in some cases, the presenting symptom is hip pain over the greater trochanter. The pain usually worsens with physical activity such as running or cycling. Pain is most intense at heel-strike. Some patients may also report lateral knee pain when walking up or down stairs. In most cases, point tenderness occurs with palpation of the lateral femoral condyle or lateral tibial condyle, especially when flexing or extending the knee, as the ITB slides across the lateral femoral condyle. Some patients may have tenderness over the greater trochanteric region of the hip.
