ITB Syndrome: Why Foam Rolling Alone Won't Fix It
IT band syndrome (ITBS) is a frustrating overuse injury that causes sharp pain on the outer side of the knee, typically appearing during runs after a predictable distance. It's one of the most common injuries in distance runners, cyclists, and hikers — and it's one of the most commonly mistreated. The foam roller has become the default response, but while it can temporarily ease discomfort, it doesn't address what's actually driving the problem.
What actually causes IT band syndrome?
The iliotibial band is a thick fascial band running from the hip to the knee. ITBS occurs when the band repeatedly compresses a layer of soft tissue over the lateral femoral condyle at a specific knee angle (roughly 30 degrees of flexion). Commonly suggested contributors include hip abductor weakness, particularly gluteus medius, and increased hip adduction (a crossover gait) during the loading phase of running, though research on risk factors is mixed.
Training load errors are also a frequent contributor: too much mileage too soon, sudden increases in gradient or surface, or insufficient recovery between sessions. We see this pattern regularly in runners around Berwick and across Casey, particularly those returning to training after a break or building toward an event like a half or full marathon.
Why foam rolling doesn't fix IT band syndrome
The ITB itself is extremely dense connective tissue — it cannot be meaningfully lengthened by rolling. What rolling does is temporarily reduce pain sensitivity by flooding the area with sensory input. This can make the next few kilometres of running more comfortable, but it doesn't change hip mechanics or address the compressive forces that caused the irritation. Runners who rely on rolling without changing anything else often find the pain keeps coming back.
The ITB runs from the hip muscles (the TFL and gluteus maximus) down the outside of the thigh, where it is anchored to the thigh bone, and inserts just below the knee on the shin. Tension in the band is influenced by how the hip loads, which is why most treatment plans focus on the hip, pelvis and running mechanics rather than local soft tissue work at the knee.
The effective approach to treating and preventing ITB syndrome
The research on treating ITB syndrome is limited and the results are conflicting: a systematic review found the quality of studies was poor and no single approach clearly better than others (van der Worp et al., Sports Medicine, 2012). In practice, most clinicians combine hip abductor and external rotator strengthening, gait changes to reduce crossover and hip drop where relevant, and temporary changes to running load. Load modification during the recovery phase is essential, but complete rest is rarely necessary and often counterproductive for runners who need to maintain fitness.

If ITB syndrome keeps cutting your runs short, a proper biomechanical assessment will identify the specific drivers. Book at RISE Sports & Spinal in Berwick and we'll build a programme around what we find, to help you get back to training.
