What You'll Learn
The TFL is a hip flexor muscle
The tensor fasciae latae (TFL) is a muscle located in the proximal anterolateral thigh, situated between the superficial and deep fibres of the iliotibial (IT) band. The TFL is one of the five hip flexor muscles, consisting of a thick bulb and a long tendon (the IT band), connecting from the outer-upper pelvis to the outside of the knee.
The TFL is a vital muscle that helps stabilise the hip and knee. It works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in a wide variety of hip movements, including flexion, abduction, and internal rotation. It also assists in knee flexion and lateral rotation through the attachment of the IT band to the tibia. The TFL's main function is to aid in pelvis stability during standing and walking.
The TFL can be located by placing your finger on the front of your pelvic bone and slowly moving down and to the outside of the thigh until you feel a ropey muscle that is the width of a finger. When your weight is on the side of the TFL, it will feel hard. When you shift your weight to the opposite leg, the TFL will feel soft and relaxed.
The TFL can become tight and shortened, especially from prolonged sitting. This can lead to pain and tightness in the front of the hip and outer part of the knee, which is noticeable when walking or going up and down stairs or hills. Treatment for TFL tightness includes dry needling, oral NSAIDs, and physical therapy.

It is a single-leg stabiliser
The tensor fasciae latae (TFL) muscle is a single-leg stabiliser, which means it is responsible for keeping us balanced while standing on one leg. Without the TFL muscle, we would immediately fall over when standing on one leg. The TFL muscle is the outermost of the five hip flexor muscles, which contract to bring the knee closer to the chest.
The TFL muscle is located in the proximal anterolateral thigh, between the superficial and deep fibres of the iliotibial (IT) band. The IT band is a long tendon that runs along the lateral aspect of the thigh, attaching to the Gerdy tubercle of the lateral tibia. The TFL muscle works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in a wide variety of hip movements, including flexion, abduction, and internal rotation. It also assists in knee flexion and lateral rotation through the attachment of the IT band to the tibia.
The TFL muscle can become tight and aggravated due to excessive physical activity, particularly in sports such as running and soccer, which require a lot of leg swinging and standing on one leg. Sitting for too long can also cause the TFL muscle to shorten and tighten, leading to pain. To relieve TFL muscle pain, deep tissue massage can be effective in breaking up the tension, knots, and trigger points in the muscle. Additionally, stretching and strengthening exercises, such as side planks, single-leg deadlifts, and skater hops, can help to improve TFL muscle strength and flexibility.
The TFL muscle is vital for our mobility, allowing us to perform activities such as skiing, standing, walking, and horseback riding. It is important to pay attention to this muscle group and ensure it is properly stretched and strengthened to maintain optimal function and prevent injuries.

The TFL is a skeletal muscle
The Tensor Fasciae Latae (TFL) is a skeletal muscle located in the proximal anterolateral thigh, between the superficial and deep fibres of the iliotibial (IT) band. The TFL is a fusiform muscle, situated on the outside of the hip, running down to the knee. It is the outermost of the five hip flexor muscles, which contract to bring the knee closer to the chest. The TFL is a small but very important muscle, essential for walking, running, climbing, and other daily activities. It works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in a wide variety of hip movements, including flexion, abduction, and internal rotation.
The TFL has two primary functions: hip flexion and single-leg stability. The hip flexion function is used when swinging the leg forward during running, lifting the knee to the chest in a marching motion, and kicking a soccer ball. The TFL's second function of single-leg stability helps us stay upright while standing on one leg. Without the TFL muscle, we would fall over immediately when standing on one leg. The TFL also acts as an accessory knee flexor, working with the IT band to stabilise the knee when it is in full extension.
The TFL can become tight, especially in situations of prolonged shortening, such as sitting for extended periods. A shortened TFL can lead to an anterior tilt of the pelvis and/or medial rotation of the femur. TFL pain can be caused by overuse or when the muscle compensates for weaker surrounding muscles. Sitting for too long can also cause TFL pain, as the muscle shortens in this position. TFL pain relief can be achieved through deep tissue massage, breaking up the tension, knots, and trigger points in the muscle.

It is a two-joint muscle
The Tensor Fasciae Latae (TFL) is a two-joint muscle, meaning it works across two joints: the hip and the knee. It is a small muscle, yet it works with several muscle groups to assist in the movement and stabilisation of both joints.
The TFL is a hip flexor muscle, consisting of a thick bulb and a long tendon, connecting from the outer-upper pelvis to the outside of the knee. It is the outermost of the five hip flexor muscles. The TFL is also a single-leg stabiliser, helping us to balance while standing on one leg.
The TFL works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in a wide variety of hip movements, including flexion, abduction, and internal rotation. It also assists in knee flexion and lateral rotation through the attachment of the IT band to the tibia. The TFL is most important clinically for aiding in pelvis stability while standing and walking.
The TFL can become tight, especially in situations of prolonged shortening, such as in a seated position. A shortened TFL can lead to an anterior tilt of the pelvis and/or medial rotation of the femur. External snapping hip syndrome is a condition where patients describe a palpable snap on the lateral aspect of their hip that occurs with a variety of movements.
The TFL can be palpated by placing one hand at the lateral side of the thigh immediately above the knee, and the other hand at the proximal anterolateral thigh. The patient is then instructed to abduct the limb being assessed. The TFL can then be easily palpable at the end range of the motion.

The TFL is a hip abductor muscle
The tensor fasciae latae (TFL) is a muscle located in the proximal anterolateral thigh, between the superficial and deep fibres of the iliotibial (IT) band. The TFL is one of the hip abductor muscles, which are necessary for staying stable when walking or standing on one leg. The other hip abductor muscles are the gluteus medius and gluteus minimus.
The TFL is a small but mighty muscle that plays a crucial role in stabilising the knee joint and influencing pelvic tilt. It is the outermost of the five hip flexor muscles, which contract to bring the knee closer to the chest. The TFL is also a single-leg stabiliser, keeping us balanced while standing on one leg.
The TFL works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in a wide variety of hip movements, including flexion, abduction, and internal rotation. It also acts via the IT band in the lateral rotation of the tibia. This lateral rotation may be performed while the hip is in abduction and medial rotation, as is seen when kicking a soccer ball.
The TFL can become tight, especially in situations of prolonged shortening, such as sitting for long periods. A shortened TFL can lead to an anterior tilt of the pelvis and/or medial rotation of the femur. Sitting for too long without stretching can produce a weak, tight TFL that causes pain.
