Iliotibial Band Friction Syndrome Essay

?Iliotibial Band Friction Syndrome
Iliotibial band friction syndrome(ITBFS) also known as ?runners knee? is a
very common athletic injury that effects the knee. Runners knee is especially prone
to long distance runners or athletes who participate in activities that require highly
repetitive running. In greater detail I will be discussing the causes of this injury
specifically the biomechanics, anatomy and symptoms involved, also ways of
preventing this injury by identifying common training errors and the appropriate
training modifications needed, and finally a variety of ways for treatment and
rehabilitation to help improve the injury.
Causes
Anatomy/Biomechanics:
The iliotibial band is a thick band of tissue that extends from the thigh(femur)
down over the knee and attaches to the tibia. When the knee bends (flexion) and
straightens (extension), the iliotibial band slides over the lateral femoral epicondyle,
the bony part of outer knee. Iliotibial band friction syndrome refers specifically to the
lateral knee pain related to irritation and inflammation to the point at which the band
crosses the lateral femoral epicondyle. This type of irritation occurs when the knee is
flexed at approximately an angle greater than 30 degrees, because the iliotibial band
shifts posteriorly behind the lateral femoral epicondyle. During extension, the band
shifts back anteriorly in front of the lateral femoral epicondyle and it is this motion
that causes friction between the iliotibial band and the lateral femoral epicondyle
which leads to irritation and inflammation within the iliotibial band.
Symptoms:
Iliotibial band friction syndrome is a condition not unique to runners, it and its
symptoms are now frequently seen in cyclists, weight lifters, skiers and soccer
players. The most obvious sign that you have ITBFS is the pain felt usually during
exercise. Runners will describe the pain on the outside part of the knee or lower
thigh. The degree of discomfort runs from dull aching sensation to a sharp stabbing
pain. The pain is not localized so most suffers cannot put their finger on one
particular spot. Suffers will generally use the flat of their hand to describe the
location of the pain. One easy self test to know if you might have ITBFS, is the point
of tenderness test. A patient with ITBFS will exhibit extreme point of tenderness at
about 2 cm over the outside part of the knee when flexed at thirty degrees. Another
common symptom is a ?creaking? noise during activity, this noise mostly occurs
during weight bearing exercise like weight lifting. This is because during weight
bearing activities the additional pressure and compression forces the contraction of
the knee joint. This leads to elevated friction over the lateral epicondyle and
increased pain. One important factor about ITBFS is that it is a problem not inside
the knee joint, but around it, which makes more easily distinguishable and treatable.
Prevention
Common Training Errors/Training Modifications:
Iliotibial band friction syndrome is an overuse injury caused by extensive
repetitive friction of the iliotibial band. The most frequent oversight runners and
athletes make is over doing it or over training. This can be controversial because if
you wish to compete at highly competitive levels what is over training? This should
be decided by the athletes themselves who should know when to make the rational
decision of knowing when to stop. Another predisposing factor for the development
of ITBFS is training error and abnormal biomechanics. Many runners make the
mistake of only running on one side of the road. Most roads are higher in the centre
and slope off on either sides. The foot on the outside part of the road is lower than
the other. This causes the pelvis to tilt to one side and tightens the iliotibial band
occurs, naturally increasing friction. Runners must always remember to try when
possible to run on flat terrain, this will greatly reduce the chances of acquiring
ITBFS. As running on flat terrain reduces friction, highly shock absorbing footwear
is also needed. In runners with normal feet, the force of running is dissipated by the
foot. However, if you have a minor abnormality in your foot anatomy, like high or
low arches, the shock from the force of the foot strike is primarily passed directly to
the knee. A good pair of shock absorbing shoes will decrease the pressure, inturn
allowing the muscles and tendons surrounding the knee, chiefly the iliotibial band to
be more relaxed reducing friction. Shoe mileage should also be considered for
serious runners or athletes. After about 500 miles or 800 kilometres most shoes loose
60% of their initial shock absorption capacity. As some one jogging leisurely or
training competitively, both should participate accordingly, knowing when not to
over do it, and knowing to implement good training habits like appropriate footwear
and stretching before and after performance. If these aspects of sport along with
others are followed avoiding ITBFS should be easily accomplished.
Rehabilitation
Treatment:
In establishing an appropriate treatment program, the severity of the present
inflammation must first be determined. Once the injury is properly assessed and the
diagnosis taken into consideration, the athlete may be placed into one of the three
phases of iliotibial band care.
The first phase of care is the Immediate Phase. This is the phase in which the
pain and inflammation must be controlled along with any poor training habits, which
some I already discussed are corrected. Achievement of these goals require a
reduction of activity and the proper administration of oral anti-inflammatories. If the
trainer sees fit, many alternate treatments may be implemented. Such as ice, heat,
ultrasound, and electrical stimulation. It should also be noted that stretching
exercises which are extremely important to combat any excessive iliotibial band
tightness are conducted in this phase.
The second phase, or the Short Term Phase becomes a consideration only if
the painful symptoms have not yet resolved within approximately 10 days of the
previous treatment. All the previous treatment should be continued with the possible
addition of a physician administering steroid injections, in two week intervals.

Further restriction of activity may be necessary. If deconditioning of the athlete
becomes a concern during this phase, he/she can participate in other activities like
swimming or cycling, as long as the activity remains pain free.

The third and final phase, the Long Term Phase is seen as an optimistical
stage. This phase begins only after the pain and inflammation symptoms have
resolved. This phase is typically in close association with the athletes return to sport.

During this stage, it is very important to prevent any reoccurrence of the resolved
symptoms. So a gradual return to play with extensive specific stretching exercises
both before and after workout is essential. If at this point pain and inflammation has
not significantly reduced, a return to play is not a good option yet. Your trainer or
physician should recommend further rest or surgery as a last resort.

Surgery:
Surgery is contemplated and seen only after many attempts of non operative
measures failed to relieve symptoms. Surgery is usually only required for those
individuals who are unwilling for many reasons, some very valid to modify their
sports participation. The surgery consists of making a 2cm incision in the posterior
fibres of the iliotibial band. This loosens the tendon some what but mostly allows for
space for the band to pass over the lateral femoral epicondyle without much of the
friction.
Iliotibial band friction syndrome (ITBFS) is an overuse injury that is most
common in those athletes that entertain highly repetitive running sports. It is seen in a
variety of athletes from soccer players to cyclists. It is the inflammation of iliotibial
band as a result of friction with the lateral femoral epicondyle. The injury is easily
detectable and the proper treatment and rehabilitation should be diagnosed. The
injury should be first be treated in a conservative manner by initiating the progression
of rest, stretching, and the moderate use of medications only if directed by a
physician. If all conservative attempts fail to achieve results then surgery might have
to be necessary. After doing this research paper I have learned a number of things,
but most importantly I believe I have learned what that pain on the outside of my left
knee that I have been experiencing for the last few months is.
