Is this the cause of pain on the outside of the knee? Let's learn about Iliotibial Band Syndrome!

Are you someone who exercises regularly, runs, or jumps? Or do you play sports like cycling, cricket, or football? When you do that, do you sometimes feel pain coming from the outside of your knee or hip bone? While many people think this is normal, something that happens when you overexert yourself, this could be a symptom of a condition called 'Iliotibial Band Syndrome' . Although the name may sound a bit strange, this is a very common condition among people who play sports and exercise. So today, let's talk about it in a simple way that you can understand.

Simply put, what is iliotibial band syndrome (ITBS)?

Imagine that you have a thick, strong band running from the hip bone to the knee on the outside of your leg. In medical terms, we call this the iliotibial band , or IT band . This is actually a special type of tissue. To be precise, it's a strong, stretchy band-like 'tendon' that connects our muscles to our bones. This IT band is what helps keep your leg stable when you bend, straighten, run, or walk.

Now, what happens if this IT band becomes too tight for some reason? Then, every time you bend or straighten your leg, this tight band starts rubbing against the bone near the knee or the bone near the hip. It's like a rope rubbing against a rock. When it keeps rubbing like this, that area becomes inflamed , red, swollen, and painful. That's what we call ITBS.

Who is most likely to develop this condition?

Although anyone can develop this condition, some people are at higher risk. It is especially common among young people, those who exercise regularly, and those who lead active lives.

• Long-distance runners: The IT band is constantly rubbing against the bones because the knee bends and extends with every step.
• Cyclists: This risk exists because the knee continues to function in the same way while cycling.
• Soccer, basketball, and hockey players: These sports put a lot of pressure on the IT band because they run, stop, and change direction all at once.
• People who ski.

In addition to those who play these sports, this condition can also easily develop in people who have certain changes in body position.

• Bowed legs.
• One leg being slightly longer than the other.
• Having knee arthritis.
• Having an inward turning of the ankle, leg, or foot while walking or running.
• Weakness of the muscles in the hips, buttocks, or abdomen. When these muscles are weak, the stability of the leg is reduced and more stress is placed on the IT band.

Why is this IT band so tight and painful?

The causes of IT band tightness and pain can be divided into two categories. One is the causes that are inherent in our body, and the other is the causes that are related to the activities we do.

Do you have these symptoms too? How do you know for sure?

The main symptom of ITBS is pain, but there are slight variations in the way and location of this pain.

• Knee pain: This is the most common and prominent symptom. The pain comes from the outside of the knee. Specifically, it is located at the bony prominence on the lower part of the thigh bone (femur), near the kneecap (lateral epicondyle). This pain is most felt when bending or straightening the leg, especially when going down stairs or downhill.
• Hip pain: Some people may experience pain on the outside of their hip without knee pain. This is because the IT band rubs against the hip bone (the `greater trochanter`).
• A clicking sound or sensation: When bending or extending the knee, there may be a "clicking" sound coming from the outside, or a sensation as if something is jumping inside.
• Warmth and redness: If you touch the painful area, you may notice that it is slightly warmer than other areas and sometimes redder.

The pain may initially feel like a burning sensation, aching, or aching, but as the condition worsens, it can develop into a sharp pain, like a knife stabbing.

How do you find this, Doctor?

When you go to see a doctor with these symptoms, the first thing he or she will do is ask you about your medical history. He or she will ask you a lot of questions, such as what sports you play, how you exercise, when the pain started, where it hurts, and how it hurts.

Then you will have a physical examination. The doctor will examine your leg, knee, and hip. In particular,

• I press my hand on the painful area.
• They bend and straighten your leg at different angles to see if the pain increases.
• Special testing methods called Noble and Ober are used to confirm whether the IT band is tight.

Most of the time, ITBS can be diagnosed based on these details and a physical exam. However, sometimes your doctor may refer you for further testing if they suspect another cause of your pain (such as damage to the cartilage in your knee).

• Ultrasound Scan: This can check for things like the thickness and swelling of the IT band.
• MRI Scan (Magnetic Resonance Imaging): This helps to 100% confirm that there is no other injury, as it can clearly see all the other parts of the knee and hip (bones, cartilage, ligaments).

Okay, now what are the treatments for this?

ITBS is a condition that can often be treated with simple treatments that do not require surgery. Treatment has two main goals: one is to reduce existing pain and inflammation, and the other is to prevent the condition from recurring.

How long does it take for this condition to heal? How can I prevent it from recurring?

If you rest properly and do the right treatment (especially physical therapy exercises), most people will recover within 4 to 8 weeks . However, if you continue to exercise despite the pain, the condition can worsen and take longer to heal. It can also sometimes lead to other knee problems, such as Patellofemoral Pain Syndrome (PFPS) .

The most important thing is to prevent this from happening again after you've healed. To do that, make these things a habit in your life.

• Warm up well before exercising. Walk for 5-10 minutes and do some light stretching exercises.
• After exercising, be sure to cool down. Walk around for about 5 minutes and do some good stretching exercises.
• Don't suddenly increase your exercise distance or speed. Increase it gradually, about 10% per week.
• Wear good quality shoes that fit your body. If you run, wear a pair of running shoes.
• Don't run on the same road or in the same direction every day. Running on the side of the road puts more weight on one leg. If possible, run on flat ground or on a track.
• Continue to do the stretching and strengthening exercises your physical therapist has prescribed. Strengthening your hip muscles is especially important.

When should I see a doctor? What questions should I ask?

If you have knee or hip pain and it doesn't go away after a few days of rest, or if the pain gets worse, definitely see your doctor . Don't put up with the pain.

When you go to see the doctor, don't forget to ask these questions.

• "Doctor, what is the real reason for my condition?"
• "Will I need to have an ultrasound or MRI?"
• "Can you recommend a good physical therapist?"
• "Will I have to have surgery?"
• "When will I be able to resume my usual sports activities?"
