Knee Injuries: Runner’s Knee

As a follow on from last month’s article discussing Jumper’s Knee (Patella Tendonitis) this month’s article covers another chronic injury that can blight the rugby knee.

Iliotibial Band Friction Syndrome (“ITBFS”)

As its common name suggests, this condition is found in runners (but can also affect cyclists). ITBFS is often referred to as an overuse injury causing pain to the outer part of the knee. However, there are other issues that can make an athlete more susceptible, particularly weak gluteus medius, tight or wide iliotibial band (“ITB”), trigger points in both areas and fallen arches (over pronation).

 
As you can see from the front-on illustration, the ITB is a superficial sheet of fascia with vertical fibres running along the outside of the thigh, connecting the hip and the knee. It is responsible for flexing, medially rotating and abducting the hip.

As the knee bends and straightens the distal ITB moves from in front to behind and back in front of the lateral epicondyle, the small bony prominence at the lower end of the femur (thigh bone) on the outside of the knee.

When this movement is repeated, as in running, this can cause friction, which more often than not leads to inflammation of the surrounding soft tissue.
 
 

    Symptoms:

  • Pain on the outside of the knee, which can radiate upwards or downwards;
  • Tightness along the outside of the thigh;
  • Pain becomes worse when running;
  • Pain when bending and straightening the knee, which intensifies when the area is pressed; and
  • Weakness in hip abduction.

Although ITBFS can be diagnosed with an MRI scan, it will not be evident with an x-ray.

Treatment

Rest and cold therapy will help to reduce inflammation and pain but if ITBFS is diagnosed the first port of call should be postural assessment and biomechanical analysis to eliminate issues in this area.

Sessions with a L4/5 Sport and Remedial Massage Therapist (“SRMT”) will help to eliminate trigger points whilst softening the ITB and surrounding tissues appropriately. If weakness is found in the gluteus medius, a therapist will also be able to help strengthen this area.

If the above treatment is unsuccessful, referral for a corticosteroid injection may be considered.

Prevention

My most preferred prevention method (as a prehabilitator) is to eliminate all the associated issues prior to activity. As always, make sure your posture and mechanics are good.

Spend time during your off season strengthening the areas surrounding the ITB, paying particular attention to the gluteus medius.

Stretching the ITB is a matter of contention as the ITB is not actually a muscle. There are many ‘ITB stretches’ recommended such as the one below but these only ‘appear’ to stretch the ITB. They actually stretch the Tensor Fascia Latae; the muscle you can see at the top of the ITB in the illustration above. However, these stretches can provide some relief in the first instance of discomfort.

Regular sessions with a SRMT will keep the area maintained throughout the season and keep the fascia at the correct tension with various techniques.

About Liz Ward

As a performance analyst, making good use of kinesiology, biomechanics and video analysis as well as a soft tissue therapist, my preference is prehabilitation, but I am sorry to say that the majority of my time is spent with rehabilitation. Although I can put myself to most things, as a rugby coach I specialise in kicking these days and as a cricket coach, pace bowling; putting my Advanced Biomechanics, Speed and Accuracy Training to good use. I am also a certified personal trainer but no longer have time to get in to the gym, preferring to work on the techniques of Olympic Lifts in my clinic. I will be providing you with regular blogs focussed on common rugby injuries with treatment and prevention advice. I am also here to help you with any questions that you may have about rugby injury prevention or treatment. View all posts by Liz Ward
