The Iliotibial Band (ITB) plays a key role in knee stability, but repetitive movements like running can cause pain and inflammation on the outer knee.
Poor foot biomechanics can contribute to ITB syndrome by affecting leg alignment and movement patterns.
What causes Iliotibial Band Syndrome (ITBS)?
Iliotibial Band Syndrome (ITBS) is triggered by repetitive knee and hip movements, often from activities like running, cycling, hiking, and stair climbing. It occurs when the IT band becomes irritated due to strain at the knee attachment point.
Common contributing factors include:
- Biomechanical issues: High arches, leg length discrepancy, and overpronation can misalign the leg, increasing stress on the IT band.
- Muscle weaknesses: Weak hip abductors and glutes force the IT band to overcompensate, leading to strain.
- Improper training: Sudden increases in distance, speed, or intensity, as well as excessive downhill running, overload the IT band.
- Poor technique: Overstriding or limited hip rotation can place excessive pressure on the IT band.
- Footwear & surfaces: Worn-out shoes, improper support, and running on hard or uneven surfaces can aggravate symptoms.
Symptoms of ITBS
The primary symptom of ITBS is pain on the outside of the knee, which worsens with activity.
Common symptoms include:
- Pain on the outer knee during walking, running, squatting, or climbing stairs
- Discomfort that flares up after exercise rather than during
- Tenderness over the IT band where it crosses the knee
- Pain radiating from the hip down the outer thigh to the knee and shin
As ITBS progresses, additional signs may appear:
- Visible tightness in the IT band
- Swelling on the outside of the knee
- A grating sensation (crepitus) due to inflammation
- Stiffness and difficulty straightening the knee
- Muscle weakness or compensatory movement patterns
Addressing symptoms early is key to preventing long-term issues and further strain on surrounding muscles. Listen to your body’s warning signs.
Risk factors for ITBS
Several anatomical, biomechanical, muscle imbalance, and training factors can increase the risk of injury, including:
- High foot arches (underpronation) or excessive foot rolling in (overpronation)
- Leg length discrepancy causing uneven stress
- Weak hip abductors, glutes, or core muscles
- Tight IT band, quads, or hip flexors
- Poor running technique or inefficient biomechanics
- Frequent hill running or downhill exercises
- Sudden increases in activity, distance, or intensity
- Running or walking on hard, uneven surfaces
- Worn-out or unsupportive footwear
- Bowlegged alignment (increased Q-angle)
- Femoral anteversion (inward-angled thigh bone)
- External tibial torsion (outward-turned shin bone)
Understanding these risk factors can help prevent ITBS by addressing underlying weaknesses and movement patterns.
