Introduction The iliotibial band is a common source of pain in runners.
The iliotibial band is a common source of pain in runners. IT band syndrome is characterized by lateral knee pain with activity. The Iliotibial band (ITB) is a lateral thickening of the tensor fascia latae that consists of dense connective tissue.
The IT band will have both superficial and deep fibrous insertions. The deep fibers of the ITB insert on the lateral femur and are historically called the Kaplan fibers. The superficial fibers will insert along the lateral tibia at Gerdy’s tubercle.
The Kaplan fibers have been identified to serve a role in rotatory stability of the knee. Despite these fibrous connections, there is still anteroposterior motion of the ITB at the level of the lateral femoral condyle with flexion and extension of the knee. The motion identified at the lateral femoral condyle does give support to this being a friction syndrome.
Case Vignette A 26 year old runner presents to the office with lateral femoral pain. You suspect IT band syndrome and are reviewing the anatomy of the IT band with your fellow. What are the femoral attachments of the IT band called along the lateral femur?
A) Kaplan fibers B) Cohen fibers C) Gerdy’s tubercle D) Osgood fibers The iliotibial band on ultrasound appears as a homogeneous fibrillar structure that is thin in appearance. Patient's with ITB syndrome can have thickening of the IT band at the level of the lateral femoral condyle. There may also be fluid located in the iliotibial bursa, which is located between the deepest portion of the IT band and the lateral femoral condyle.
If you are experiencing symptoms that may be related to ultrasound guided it band injection, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
