ITB syndrome is relatively common among the runners and triathletes that I have treated. It’s described variously as a sharp pain on the lateral (outside) edge of the kneecap, so painful that its like someone is poking a hot pin in there and twisting it around. It can also be felt further up the Band, toward the hip, but for this article, Im going to concentrate on the knee problem.

As you would expect, this tends to have an effect upon running style, generally a pronounced limp, followed swiftly by a walk, and then a phone call home to get picked up.
For those who don’t know, the Illiotibial Band is a wide strip of collagen fibre stretching from the hip down to the knee. It attaches at proximally (at the top) to the fascia around the hip and (more importantly) to a muscle called the Tensor Fascia Latae (hereafter known as TFL). The TFL is kind of embedded in the fascia as opposed to being the controlling muscle of it.
Distally (at the bottom), the ITB attaches to the fascia around the kneecap on the lateral (outside) of the knee. It is here that the pain from ITB syndrome usually hits.

Why does it happen?!
I’m going to have to split this up into 2 sections, Fire and Smoke.
The actual underlying reason this happens is based in the gluteal region, (your bum). As you walk/ run, there are a series of 6 muscles called the Deep 6, (or lateral rotators), their job is to keep the leg in the optimal position with the hip. In effect they act like a guy rope to keep the leg in line.
Just for reference, these muscles in this group are the Piriformis, Obturator Externus, Obturator Internus, Quadratus Femoris, Gemellus Inferior and Gemellus Superior.
|The Deep 6 (the observant of you will notice I have only drawn 5 on there, the Obturator Externus is best drawn on from the front- and a bit more difficult to visualise from the back- so to prevent confusion, I refrained from drawing it.)|
Other muscles involved in this action are Gluteus Maximus, Gluteus Medius (both in your bum), also Psoas major, Sartorius and Iliacus, but we shall skip over the last few for the time being.
Now, if these muscles are not working as they should, ie. they aren’t strong enough, or they are inhibited (as most of the triathletes I have seen), they are not able to stabilise the leg in the correct position as you walk/run. The only thing that the body can really do at this point is use the ITB – a length of non-contractile tissue – to hold the leg – and therefore the knee – in the right place.
So instead of a group of 10 or so muscles keeping the leg in line, the body is relying on a single piece of collagen – whose original job is to keep the knee-cap in the right place – to keep the whole leg in line with the hip.
|All the muscles around your bum. Its quite packed in there, if they aren’t working properly, or are inefficient, its pretty obvious that something is going to have to give. Generally, its going to be the ITB.|
We know that the ITB is now doing the vast majority of the work because of the inefficiencies of the muscles in the bum. The ITB is made up of collagen – which is an awesome substance. It responds to stress by getting thicker and tighter. So, as you pound your way down the road (or the fell), the ITB is getting thicker and tighter all the time, if it is that tissue that you are relying upon to keep the hip, leg and knee in line, it’s going to get tighter. As it does so, it begins to pull the kneecap laterally (outwards), and can have the effect of making the kneecap track incorrectly – wearing out the inside of the kneecap – but the beginnings of pain are generally the feeling of tightness on the lateral (outside) edge of the knee- just where the ITB attaches to the fascia.
A lot of people swear by foam rollering, or “stripping” the ITB, which is as painful as it sounds. If it has gone far enough, the collagen has plasticised (my words) itself into a form that is supporting the knee and the leg. The stripping of the band is necessary to re-educate the collagen so that it loosens off and doesn’t pull on the kneecap anymore.

The problem with this is that its taken a few years to get into this state, and just rollering it a few times isn’t going to make it just go away. You have lengthened it a bit, but as stated, its like plastic. It needs a long time to go back to the way that it was. If you have ITB pain, you are going to need to be using that roller for quite some time before it gets educated to go back to the way it should be.

If you do go to someone and they start digging into the ITB in a way that makes your eyes bulge and your throat go hoarse, they should also be looking at that muscle we spoke about earlier- the TFL- its a small muscle, embedded in the ITB up toward the hip. This muscle helps create tension in the ITB, and if the collagen band itself is being treated, the muscle which assists it should definitely be looked at as well.
If you just get the ITB “stripped” thats just the start. The Lateral Rotator muscles need to be trained to work better. If they don’t do their job, the ITB will continue doing more than it should be doing, and hey presto, it will come back, and you’ll do the whole thing all over again.
If you see a physio/massage therapist who just does your ITB and sends you on your merry way, get another one. They are using you as a cash cow.
They should be looking at the musculature around the hip, the muscles may be weak/inhibited, they may be biomechanically inefficient and need stimulating massage as well – (just as a warning, this may be as uncomfortable as the ITB stripping). They should also give you ideas as to what to do to strengthen the muscles in order to help reduce the pain in your knee.

Golden Rule 1
If you have ITB syndrome, get it seen to by a professional, the quicker you get it sorted, the quicker you will be running pain free, and the less chance you have of the injury compounding.
Golden Rule 2
If you talk to a professional about knee pain, and you HAVEN’T hit your knee – but they only look at the knee, go to someone else. If there hasn’t been a contusion to the knee structure itself, the issue is far more likely to be in the hip or the foot. And if these are not looked at in some detail, well, thats a bad thing.
I hope thats been a decent intro into Illiotibial Band Syndrome, what it is and why it happens. If you have any comments, I’d be happy to hear them.
