What is a potential repercussion of tight iliotibial band?

1. Knee instability

2. Increased hip flexibility

3. Enhanced balance

4. Improved posture

The correct answer is: Knee instability

The iliotibial (IT) band is a thick band of connective tissue that runs along the outside of the thigh from the hip to the knee. When the IT band is tight, it can become a source of friction and strain on the knee joint, particularly during activities that involve bending and straightening the knee, such as running or walking. This tension can lead to knee pain, often referred to as iliotibial band syndrome, which is characterized by lateral knee pain and can compromise stability in the knee. A tight IT band can restrict the smooth mechanics of the knee joint, reducing its ability to stabilize properly during movement. This instability can increase the risk of injury, affecting overall performance and potentially leading to issues such as patellofemoral pain or other knee-related injuries. In contrast, tightness in the IT band would not contribute to increased hip flexibility, enhanced balance, or improved posture; these options do not reflect the effects caused by a tight IT band. Therefore, knee instability stands out as the most relevant repercussion of a tight iliotibial band.
