What is ITB syndrome?

What is ITB syndrome?

• A. Inflammation of the medial collateral ligament.
• B. Posterior knee injuries from hamstring strains.
• C. Patellar instability at the lateral knee.
• D. Iliotibial band friction over the lateral femoral epicondyle causing lateral knee pain, often from repetitive running or cycling.

Answer: (D)

Iliotibial band syndrome is an overuse injury where the iliotibial band friction slides over the lateral femoral epicondyle, causing lateral knee pain. It commonly affects runners and cyclists because repetitive flexion and extension of the knee with a tight or tense IT band leads to irritation at the outer knee. You’ll often feel pain on the outer side of the knee that worsens with activity, along with tenderness a bit above the knee on the outside. Several factors can contribute: repetitive mileage increases, downhill running, improper footwear, leg alignment problems, and weakness in hip abductors (gluteus medius) or core that lets the IT band become too tense. Management focuses on reducing inflammation and addressing mechanics: rest or cross-training to ease the load, ice, NSAIDs if appropriate, and a physical therapy program emphasizing gradual return to running, hip-strengthening (especially abductors and stabilizers), IT band and surrounding tissue stretches, and sometimes gait or training modifications. In most cases, symptoms improve with a structured rehab plan and gradual return to activity. The other choices describe different knee issues—medial ligament inflammation, posterior knee injuries from hamstring strains, or kneecap instability—so they don’t match the mechanism or location of IT band syndrome, which is specifically friction of the IT band over the outer knee.
