Don’t let this common cause of knee pain slow you down – ITBS (IT Band Syndrome)
ITBS is one of the most commonly seen overuse injuries among our runner clients for their knee complaints. It is often the result of an overuse injury. In some athletes, repeated knee bending causes the ITB to produce friction over the rounded end of the thighbone or compression of the tissue underneath it. This results in persistent pain on the outer side of the knee which worsens with over-activity.
ITBS = INFLAMMATION OF THE IT BAND
Pain symptoms of ITBS:
• Sharp pain at the outside of knee joint
• Maybe in one or both knees
• Is an aching, burning feeling that sometimes spreads up the thigh to the hip
• May start near the end of your activity, at first, but comes earlier as the condition worsens
ITBS can be aggravated by:
• Running in poor footwear
• Poor bike fit for cyclists
• Running on uneven or downhill terrain
• Running long distances
• Foot issues – e.g. bow legs, excessive pronation, leg length discrepancy(>1cm), etc
• Muscular imbalances at your pelvis and around the knee
The problem area may be somewhat swollen or exhibit crepitus (feel a crackling, grating, or popping sensation) or snapping when bending the knee. Your therapist will do a full evaluation of the strength and range of motion of both legs, hips, and pelvis.
A functional assessment including functional stability tests and a running assessment (should the client be a runner) will also be done.
MRI (Magnetic resonance imaging) may show thickening of the ITB and fluid accumulation under the ITB.
With a functional approach to treatment, most athletes with ITBS return to sports in roughly 6 weeks. The IT band runs along the thigh, functions to our knee, turns the knee inwards and moves the leg outwards (hip abduction).
Acute phase – when in pain and inflammation at the lateral knee
Goal: To decrease pain and inflammation
How? Rest is the first line of defense against further damage.
For a low-grade injury, this may mean a few days off from training and amending external causes. Buying new shoes, avoiding downhill runs, or running the opposite direction on a track may clear up the condition quickly.
If the inflammation is more severe than the discomfort and swelling, it should be managed with modalities and non-steroidal anti-inflammatory drugs. If obvious swelling and pain persist despite conservative management, a localized corticosteroid injection might be warranted.
Sub-acute phase – when the acute pain and inflammation subsides
Goal: To improve flexibility, joint range of motion, and strength in open-chain positions
How? The therapist will progress to recovery phase activities when the athlete can execute resisted exercises without pain.
Once the athlete, can do resisted functional stability exercises with no discomfort then a return to sport should be planned. Obviously, there will be a gradual increase in load and intensity. External factors that were highlighted earlier should also be addressed such as bike fit, footwear, running terrains, etc.
