IT Band Syndrome: Why That Sharp Knee or Hip Pain Might Not Be What You Think

A Common Overuse Injury That Trips Up Hikers, Trail Runners, Cyclists, and Skiers in the Flathead Valley

I recently worked with a patient who had just come back from a long hiking trip in Glacier National Park. He is fit, active, and spends most of his summers out on the trails above Whitefish and Olney. On the second day of a multi-day route, a sharp, burning pain showed up on the outside of his knee. It did not feel like a fall or a twist. Nothing specific had happened. But by the time he reached camp that evening, descending had become something he was dreading.

He assumed he had done something to his knee. When he came in, I evaluated his movement patterns, hip strength, and the way load was traveling through his lower body. What we found was not a knee injury at all. It was his IT band — and understanding that distinction made all the difference in how we approached his recovery.

What Is the IT Band?

The iliotibial band — commonly called the IT band — is a long, thick band of connective tissue that runs along the outside of the thigh, from the hip all the way down to just below the knee. It is not a muscle you can strengthen or stretch in the traditional sense. It is dense, fibrous tissue whose job is to stabilize the knee and hip during movement.

At its upper end, it connects to the tensor fasciae latae and the gluteus maximus — two muscles that play an important role in hip stability. At its lower end, it crosses the outside of the knee joint, where it can become irritated when it repeatedly rubs against a bony prominence of the femur during repetitive bending and straightening of the knee.

That irritation is what we call IT band syndrome, and it is one of the most common overuse injuries we see in active people throughout the Kalispell, Whitefish, and Flathead Valley area.

Why IT Band Pain Can Be So Confusing

IT band pain has a way of catching people off guard. It often appears during activity rather than before it begins, and it tends to feel sharp or burning rather than the dull ache people associate with muscle soreness. Many patients describe it as a stabbing sensation on the outside of the knee, or sometimes higher up at the hip, that comes on suddenly and seems to worsen with continued movement.

Because the pain shows up at the knee, most people assume the knee is injured. But the knee is often just where the symptoms are felt, not where the problem originates. The real drivers of IT band syndrome usually live higher up — in the hips, glutes, and the way the entire lower body is moving together.

One of the most telling signs is how the pain behaves on a descent. Hiking downhill, running downhill, or skiing steeper terrain tends to load the IT band significantly more than flat or uphill movement. If your outside knee pain reliably gets worse going down, that is a meaningful clue.

Who Gets IT Band Syndrome — And Why It Happens Here

IT band syndrome is what we call an overuse injury. It develops when the tissue is loaded more than it can recover from, often due to a combination of training volume, movement mechanics, and underlying muscle weakness.

In the Flathead Valley, we see it frequently in:

Hikers and trail runners tackling the long descents in and around Glacier National Park and the Whitefish Range

Cyclists who ride the area’s back roads and mountain terrain, particularly those who have recently increased mileage

Skiers at Whitefish Mountain Resort, especially later in the season when fatigue begins to affect alignment and technique

Runners who have recently added miles, changed surfaces, or returned to training after time off

Golfers who walk the course and are on their feet for several hours at a time across multiple rounds per week

What these groups have in common is sustained, repetitive lower body movement. IT band syndrome rarely develops from a single incident. It builds gradually, often signaling that the body has been working around a weakness or imbalance for longer than it was sustainable.

The Real Source of the Problem Is Usually the Hip, Not the Knee

This is one of the most important things I want people to understand about IT band syndrome: the pain may be at the knee, but the cause is almost always rooted in how the hip is functioning.
When the hip abductors — particularly the gluteus medius — are not doing their job well, the femur drops inward with each step. That shift in alignment increases the tension and friction on the IT band as it crosses the outside of the knee. Over enough repetitions, on enough miles of trail or road, the tissue becomes irritated and inflamed.

Rolling and stretching the IT band directly may provide some temporary relief, but it does not address why the band was under excessive stress in the first place. Until the hip is addressed, the problem tends to return.

Other contributing factors we commonly find during evaluation include:

• Weakness in the glutes and hip external rotators
• Poor single-leg stability, meaning the knee tends to cave inward when weight is placed on one leg
• Tightness in the tensor fasciae latae, the muscle at the top of the IT band
• Training load that has increased faster than the tissue had time to adapt
• Foot mechanics or footwear that affect how load distributes through the lower limb
• Common Signs That Your IT Band May Be the Issue

IT band syndrome tends to present in recognizable patterns. You may want to have it evaluated if you are experiencing:

• Sharp or burning pain on the outside of the knee, especially when descending hills or stairs
• Pain that begins after a certain distance into a run or hike and worsens as you continue
• Tenderness when pressing on the outer knee, roughly two inches above the joint line
• Hip pain on the outside, sometimes felt as a deep ache where the IT band connects near the pelvis
• Pain that feels better at rest but returns quickly when activity resumes
• A sense that your knee feels unstable or that you are guarding how you land on a particular leg

Some patients also notice a snapping or clicking sensation on the outside of the hip, which can indicate that the IT band is moving over the greater trochanter with certain movements. This is a separate but related presentation worth having evaluated.

How We Treat IT Band Syndrome at Physio Whitefish

Effective treatment for IT band syndrome requires understanding the full picture of how someone moves. That means a thorough evaluation of the hip, knee, and lower limb — not just the location where the pain is felt.

At Physio Whitefish, our approach typically includes:

Hands-On Manual Therapy

We use manual techniques to address tissue tension in the IT band and surrounding structures, as well as the TFL, hip rotators, and lateral quad. Dry needling is often highly effective for releasing trigger points in the TFL and glute complex that contribute to IT band tightness.

Hip Strengthening and Neuromuscular Re-Education

Because hip weakness is almost always part of the picture, targeted strengthening of the glutes and hip abductors is central to lasting recovery. We also work on movement patterns — teaching the body to recruit those muscles properly during the activities that caused the irritation in the first place.

Load Management

In many cases, symptoms can be managed without stopping activity altogether. We help patients understand how to modify training volume or intensity during recovery so they can continue doing what they love while the tissue heals. For someone preparing for a ski season or a summer trail race, this matters enormously.
Gait and Movement Analysis

For runners, hikers, and cyclists, we can evaluate how movement mechanics may be contributing to the problem and offer targeted cues or adjustments that reduce load on the IT band during activity.

What You Can Do at Home

While a proper evaluation is important for identifying the root cause, there are things you can do between sessions — or as a first step if your symptoms are mild.

1. Hip Hinge and Single-Leg Strength Work
Romanian deadlifts and single-leg deadlifts are among the most effective exercises for building the hip and glute strength that protects the IT band. Start with a light resistance and focus on keeping the standing knee tracking over the second toe, not caving inward. Two to three sets of eight to ten repetitions on each side, a few times per week, is a good starting point.

2. Clamshells with a Band
Lie on your side with hips stacked and a light resistance band just above the knees. Keeping your feet together, rotate the top knee upward like a clamshell opening. Go slowly and make sure the movement is coming from the hip, not from rocking the pelvis backward. This directly targets the gluteus medius, which is often underactive in people with IT band syndrome.

3. TFL and Hip Flexor Release
Using a foam roller or a firm ball on the outer hip — not the outer thigh or knee — can help reduce tension in the tensor fasciae latae. Position the ball just below and forward of the hip bone, where the TFL sits, and allow sustained gentle pressure rather than aggressive rolling. Spend sixty to ninety seconds on each side, breathing slowly to encourage the tissue to relax.

4. Modify Your Descent Mechanics
On trails or stairs, try taking slightly shorter steps going downhill and focus on landing with a soft, slightly bent knee rather than a straight leg. This small adjustment reduces the repetitive load at the point where the IT band crosses the knee. It takes practice, but many patients notice a significant reduction in symptoms once they make this shift.

5. Avoid Overstretching the IT Band Itself
One of the most common things people try when they have IT band pain is aggressively stretching the band by crossing one leg over the other and leaning to the side. Because the IT band is dense connective tissue rather than a traditional muscle, this kind of stretch does not meaningfully lengthen it and can sometimes increase irritation. Your time is better spent on the hip strengthening and mobility work described above.

Do Not Wait for It to Go Away on Its Own

IT band syndrome has a way of becoming a recurring problem for people who push through the early warning signs. What begins as discomfort at mile eight of a trail run can progress to pain that shows up at mile two, then at the trailhead, then on the walk to your car.

The good news is that when the underlying cause is properly identified and addressed, most people recover fully and return to the activities they love — often stronger and more resilient than before. My patient from Glacier is back on the trails, and he now does a short hip strengthening routine before every long outing. He has not had a recurrence.
