    Tensor Fasciae Latae

    What is the tensor fasciae latae muscle?

    The tensor fasciae latae (TFL) is a muscle located on the front and outer side of the thigh, just above the hip joint. It works in conjunction with the gluteus maximus, gluteus medius and gluteus minimus in hip flexion, abduction, and internal rotation. The TFL also helps stabilize the hip and knee joints. (1)

    Origin, insertion and function

    Origin:

    The Tensor Fasciae Latae originates from the anterior superior iliac spine (ASIS) which is a bony protrusion located at the front and top of the hip bone.

    Insertion:

    The Tensor Fasciae Latae muscle inserts into the iliotibial tract (IT band) which is a thick band of fibrous tissue that runs down the lateral aspect of the thigh.

    Function:

    The Tensor Fasciae Latae muscle primarily functions as a hip flexor, hip abductor and also helps in internal rotation of the hip. It also works as a stabilizer of the knee and hip joints. It is involved in activities such as walking, running, climbing stairs and many other activities which require the hip and knee to move together.

    Common signs of a weak tensor fasciae latae muscle

    Signs that you may have a weak tfl muscle include:

    • Difficulty in standing on one leg
    • Knee pain or instability
    • Hip pain or weakness
    • Poor balance and coordination
    • Poor posture
    • Difficulty in performing activities such as running, jumping, or climbing stairs
    • Anterior pelvic tilt, which causes the lower back to arch and the hips to jut forward
    • Increased risk of injury to the knee or hip joint.
