How to tell the difference between the two most common knee problems in runners

Credentials and qualifications
I am a writer and retired Registered Massage Therapist (unusually well-trained for a massage therapist, a 3000-hour program). I’m almost done with a Bachelor of Health Sciences degree. I am a peer reviewer for The Natural Standard, and a copyeditor for Science-Based Medicine. My most important qualification is more than a decade of workaholic post-graduate study, clinical experience, and constant conversations with readers from around the world, including many experts who have provided countless suggestions and criticisms.

This simple guide will quickly help you determine kind of runner’s knee pain you have, and then direct you to more detailed resources for the diagnosis that fits best. There are two common kinds of runner’s knee” conditions:
- pain on the side (iliotibial band syndrome, or ITBS)
- pain on the front (patellofemoral pain syndrome, or PFPS)
Of course, there are some other causes of knee pain. However, the great majority of knee pain in runners is going to be one of these two. They usually don’t occur together, although that can happen.
Knee pain in runners is usually no big deal, but it can get ugly
Both kinds of runner’s knee are usually easy to recover from — most people just need a little ice and rest.
But both conditions also have a tendency to become chronic and extremely frustrating in a few unlucky runners — several new cases in every marathon! The trouble is, when the pain is new, it’s impossible to know which way it’s going to go. Maybe it will go away quickly … and maybe it won’t.
When knee pain is new, it’s impossible to know if it’s going to turn out to be a chronic problem.
Unfortunately, there’s no way to know in advance if your case of runner’s knee will be stubborn, so it’s a great idea to be well-prepared and well-informed just in case. Because both conditions are shockingly hard to get competent treatment for. Both are misunderstood by most doctors and therapists.
Many runners with knee pain don’t prepare. They get help slowly, and then it takes weeks to realize that they aren’t getting good help. By that time, the training schedule is blown to hell.
Tell the difference at a glance
The easiest way to tell the difference between the two conditions is simply by the location of the symptoms. PFPS affects the kneecap and surrounding area. Don’t confuse it with iliotibial band syndrome (ITBS) which definitely affects primarily the side of the knee. PFPS may be felt in a wider area, but will still have an epicentre on the kneecap. ITBS will rarely spread much beyond its hot spot on the side of the knee.
ITBS has a narrow definition: it refers only to strong pain on the side of the knee at a specific anatomical location (the lateral epicondyle of the knee). Pain that is primarily in the hip or thigh is often mistakenly diagnosed ITBS. This is not possible by definition.
PFPS has a much broader definition: it is a “condition of conditions,” with many possible variations and causes.
Diagnose your runner’s knee
Just check the knee symptoms that apply to you. Whichever side gets more checks … that’s what you’ve probably got. Check all that apply. (Note: this is not a form, you do not have to “submit” it … just count checks!)
| Iliotibial Band Syndrome (ITBS) | Patellofemoral Pain Syndrome (PFPS) | ||
|---|---|---|---|
| The epicentre of the pain is on the side of the knee. Symptoms may occur nearly anywhere around the entire knee, particularly in severe cases, but the worst spot has to be on the side of the knee. | The epicentre of the pain is somewhere under or around the kneecap. As with ITBS, symptoms may occur nearly anywhere, but it will usually be mainly on the front of the knee. | ||
| There is a spot on the side of your knee, right around the most sticky-outy bump, that is sensitive to poking pressure, and your kneecap is not particularly sensitive when pushed firmly straight into the knee. | It’s not very comfortable pushing your kneecap straight onto your knee, but there is no particularly sensitive spot on the side of your knee. | ||
| Pain tends to be worse when descending stairs or hills, and is either not painful at all or noticeably less painful when ascending. | Pain tends to be worse when ascending stairs or hills, but may be painful both ascending and descending. | ||
| Started while going downhill. | Started while going uphill. | ||
| Both PFPS and ITBS can start over the course of a few hours or a day, but ITBS almost always does. If the pain started relatively quickly, check this box. | If your pain grew relatively slowly, over months or years, check this box. | ||
| Doing a deep knee bend does not especially hurt. | Doing a deep knee bend definitely hurts. | ||
| Pain is not particularly affected by sitting, although it might get worse after sitting for quite a while (longer than an hour). | Pain is clearly aggravated by sitting with knees bent. When you get up, it hurts more than it did when you sat down. | ||
| You do not have any obvious structural problems in the legs. | You are a little knock-kneed, have flat feet, or kneecaps that seem to be kind of at a funny angle. | ||
| Symptoms tend to be quite consistent and predictable, with only minimal changes in the intensity of the epicentre over time, and almost no change in the exact location of the hottest spot. | PFPS may also have consistent symptoms, in which case you can’t really check either side for this point. However, if you experience seemingly mysterious fluctuations in intensity or location — if you find that the problem is just not very predictable — this is a strong indicator that you have PFPS, not ITBS, and so you should check this side. | ||

Why buy a knee pain tutorial?
Because you get what you pay for. If you go with the free stuff, you’ll get a confusing mess of obsolete and inadequate information. If you pay a few bucks, you’ll get detailed, referenced, and current information — more and better than anything you’ll get from your doctor, physiotherapist, or the bookstore.
I know from long experience that my customers usually start out thinking, “Nah, I’ll try to find something free online.” Or “I’ll just go to my physiotherapist.” Then, two weeks later or six weeks later or six months later, they end up back here … and finally finding out how runner’s knee really works, and how to best get rid of it.
I do not offer a foolproof system for beating either ITBS or PFPS. There is simply no such thing! But I know that you will understand your knee pain better than most health care professionals by the time you are done. It’s just like coming to my office and having a nice long conversation about it, where all your questions get answered.

Shouldn’t you get looked at by a health care professional?
That would be the correct thing to say in a legal disclaimer (and I do). But the truth is that a lot of knee pain is misdiagnosed by so many health care professionals that you are just as well off — perhaps even better off — with a detailed and referenced self-help guide.
Of course, if your symptoms don’t seem to match either column very well, if your case is atypical in any way, then it probably is a good idea to consult . There are other causes of knee pain!
Lots of knee pain is misdiagnosed by “health care professionals.”
But if you fit one profile or the other fairly well, then you can trust this diagnosis as a starting place. It’s based on years of study and experience writing and teaching about runner’s injuries. This website is devoted to offering the most level-headed, evidence-based information possible.
