GROSS ANATOMY

Detailed explanation-1: -The main function of this muscle is to produce the extension and lateral rotation of the leg on the knee joint. Additionally, it contributes to the movements of the thigh, acting as a relatively weak abductor and medial rotator on the hip joint.

Detailed explanation-2: -Though small in size, the TFL works with several muscle groups to assist in the movement and stabilization of both the hip and the knee. It works with the gluteus medius and gluteus minimus to internally rotate and abduct the hip and with the gluteus maximus via the IT band to abduct the hip.

Detailed explanation-3: -The tensor fasciae latae (TFL) is a muscle on the front of the hip that connects to the lower leg via the IT band. It is positioned above the gluteus minimus and some of the gluteus medius muscle. The functions of the TFL muscle are to help flex, abduct, and medially rotate the hip.

Detailed explanation-4: -The most effective stretch for the TFL is in the knee-down hip flexor stretch (see figure 4). If you are stretching the left TFL: Kneel on the left knee with the right leg at 90 degrees hip flexion and knee flexion. Push the left hip forward until the slack is taken up (this takes up the flexion component).

Detailed explanation-5: -The tensor fasciae latae is a tensor of the fascia lata; continuing its action, the oblique direction of its fibers enables it to stabilize the hip in extension (assists gluteus maximus during hip extension).
