Iliotibial Band Friction Syndrome (ITBS). Development of ITBS. Results from repetitive bending and straightening of the knee over a long period of time such as in: Cyclists Long distance runners
E N D
Results from repetitive bending and straightening of the knee over a long period of time such as in: • Cyclists • Long distance runners • The friction from the fascia gliding over the lateral femoral condoyle irritates and inflames the distal insertion of the IT band fascia • Can also develop in fast growing adolescents
Other factors which can lead to development: • Abnormal mechanics of the hip, knee, and/or foot • Poor hip muscle strength and/or endurance • Decreased flexibility • Worn out shoes • Uneven surface training
Diffuse pain over lateral aspect of the knee using the palm of the hand • Pain starts insidiously, worsens after a person exercises and the pain onset time gets closer to initiation of the an exercise session
The Ober’s test can indicate IT band tightness • Pain increases likelihood that the patient has ITBS • MRI can aid in diagnosis
Patient positioned in side-lying • Patient’s hip is extended, abducted and patient’s knee flexed. • Clinician allows the proximal part of the leg to drop passively onto the contralateral limb. • Considered positive when the ipsilateral legs fails to lower.
Patient education and activity modification • Initial treatment should include heat and cryotherapy to decrease inflammation • IT band massage • Stretching of affected limb • Strengthening of affected limb • Referral for corticosteroid injections can help reduce inflammation
A majority of patients will respond positively to conservative treatment • The few who do not will require surgical intervention
