IT Band Syndrome (Iliotibial Band Syndrome)

Iliotibial band syndrome is an overuse injury that affects the outer thigh and knee region, commonly seen in runners, cyclists, and athletes. It occurs when the IT band—a thick band of connective tissue running from the hip to the shin—becomes tight or inflamed, leading to friction and pain on the outside of the knee.

Causes include repetitive motion, poor biomechanics, muscle imbalances, or inadequate stretching. Symptoms often include tightness in the outer thigh and sharp or burning pain at the outer knee, especially during activity.
