- Structural abnormalities, such as a short, tight IT band
- Problems related to the foot, ankle, or hip
- Opposing muscle imbalances, such as the quadriceps stronger than hamstrings
- A prominent lateral femoral epicondyle, the bony structure on the outer side of the knee
- Inward rotation of the leg
- Angle where knee flexes
- Legs of different lengths
- Certain sports with repetitive motions, such as running and cycling
- Incorrect training technique
- Increasing cycling or running mileage too quickly
- Running up and down hills
- Using damaged or worn out equipment or footwear
- Wearing improper shoes for a sport or athletic activity
- Athletic equipment that is not properly fit to the user, such as a bicycle
- Dull aching or burning sensation on the outside of the knee during or after activity
- Sharp stabbing pain on the outside of the knee during or after activity
- Pain that shows up in the hip, known as referred pain
- Progressive, worsening pain
- Snapping, creaking, or popping when the knee is bent and then straightened
- Obers test—determines the tightness of the ITB
- Rennes test—specifies the area of pain while full weight is placed on the bent leg
- Nobles test—determines the area of pain while the leg is flexed at a certain angle
- Rest—Activities may need to be restricted. Normal activities will be gradually reintroduced as the injury heals.
- Ice—Ice therapy may help relieve swelling. Heat therapy may be advised when normal activities are reintroduced.
- An orthotic device may be advised to help control rotation of the foot and stabilize the knee.
- Learning proper training techniques
- Increasing mileage run gradually
- Wearing appropriate shoes for each sport
