ITB and knee pain in runners

Running

Our NU Moves Physio team recently debated the current beliefs surround the ITB and how it can give you lateral (or outside) knee pain which is also referred to as ITB syndrome. Here is a simple take home message from a complex discussion.

* The diagnosis of ITB syndrome can be made clinically without investigations

* The lateral meniscal cartilage of the knee needs to be considered as a possible source of pain which may require MRI imaging. A clinical assessment will predict if this is likely.

* The most common cause of the problem is an increase in the amount of running or ‘load’ on the knee. Treatment of acute ITB syndrome must include initially managing the load to help reduce inflammation.  This is usually via modifying the running program.

* The hip is the key to controlling this problem. Most importantly the strength and timing of the gluteal (buttock) muscles need to be sufficient to hold your pelvis and leg stable enough during running. Secondarily having enough flexibility in the hip flexor muscles often helps get the gluteal muscles functioning better.

* Rolling the ITB is a common form of treatment utilised if tightness is perceived as part of the problem. If rolling gives you relief of pain associated with running or any other exercise then we cannot argue with that however understanding the reason behind why it may or may not help is the challenging part. Roll it if it helps you but make sure you start your rehab at the hip.

Knee pain – what is valgus collapse

One of the most common joint problems associated with exercise is pain in the front of the knee (patella). It is commonly labelled runners knee or jumper’s knee but often just walking on slopes or stairs can be the source of the pain. If we exclude degeneration of the cartilage under the patella (which is diagnosed with MRI scans), this type of knee pain can be effectively managed.

Knee pain and valgus collapseThe greatest external load on the front of the knee is due to poor movement pattern, where the knee goes inwards towards the other leg rather than straight ahead in line with the middle of the foot. This is termed valgus collapse.

Valgus collapse is a strength and movement problem which can be corrected with specific exercises targeting the right muscles. A thorough physiotherapy assessment should consider:
• Muscle length (especially the outer thigh)
• Muscle strength (particularly at the hip)
• Foot mechanics / posture
• And the way you move (muscle control or coordination)

The treatment is a series of pain free exercises that address the cause of the problem. Taping the knee is a short term option for reducing pain. Sometimes changes in footwear and / or orthotics can also assist with pain reduction, but neither replaces getting stronger and moving better. If you have persistent pain in the front of the knee, have it assessed and get a prescribed exercise plan.
