What are the three functions of the sartorius?
The sartorius muscle crosses both the hip and knee joints, producing movements on both of them. At the hip joint it is capable of flexion, external rotation and abduction of the leg. The contraction of sartorius can also cause flexion of the knee joint and inward, or medial, rotation of the tibia against the femur.

It can also cause an asymmetrical gait. For individuals who sit for long periods, tight hips and tight hip flexors including the sartorius are common. As a result, hip pain or an uneven gait may occur. However, the anterior hip pain caused by a tight sartorius is often mistaken for issues with the psoas and iliacus.
Can a tight sartorius cause knee pain?
If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This condition usually occurs in athletes from overuse and is a common cause of chronic knee weakness and pain.
What movement does the sartorius perform?
The function of the sartorius is unique in that it can serve as both a hip and knee flexor. The origin for the sartorius is the anterior superior iliac spine, sharing this origin with the tensor fascia lata. At the hip, it acts to both flex the hip as well as externally rotate.
What causes sartorius pain?
A sartorius muscle strain can cause pain in your hip or knee, depending on the area of injury. This muscle can be pulled or strained during high-impact activities such as sprinting, jumping and running. Activities that make you forcefully push off place a lot of strain on this muscle.

Deep to the sartorius is the quadriceps femoris muscle. As it crosses from the lateral to the medial side of the thigh, the sartorius muscle crosses the surfaces of the iliopsoas, pectineus and adductor longus muscles. The tensor fasciae latae muscle originates just lateral to the proximal attachment of the sartorius muscle.
Where does the Sartorius muscle originate?

What is the pes anserinus?
The inserting tendons of these three muscles form a wide aponeurotic sheath called the pes anserinus. Some fibers from the inferior part of the tendon blend with the medial collateral ligament of the knee joint, and the deep fascia over the medial aspect of the leg, while some superior fibers blend with the knee joint capsule. These connections contribute to the medial stability of the knee joint.
Which muscle is the medial margin of the adductor longus muscle?
The triangle is completed superiorly by the inguinal ligament and medially by the medial margin of the adductor longus muscle. The structures found within the triangle, the femoral artery, vein and nerve, therefore, lie medial to the sartorius. The femoral artery continues inferiorly, deep to the sartorius.

It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. It passes behind the medial condyle of the femur to end in a tendon. This tendon curves anteriorly to join the tendons of the gracilis and semitendinosus muscles in the pes anserinus, where it inserts into the superomedial surface of the tibia.

When you make sure that exercise is one that accentuates external rotation of the hips, such as plie squats or frog squats, you ramp up the overload on your sartorius muscles considerably.
What is the function of the Sartorius?
Combining all of these functions into one movement, the sartorius pulls the foot and ankle toward knee of the opposite leg. The action of the sartorius is used in many situations, such as crossing the legs so that the ankle rests on the knee of the opposite leg; sitting cross-legged; or looking at the sole of one’s foot.
Where does the Sartorius muscle come from?
The sartorius muscle arises from the anterior superior iliac spine on the lateral edge of the hip bone. From the lateral hip, it descends obliquely across the hip joint and thigh, running medially and inferiorly toward the medial edge of the knee. At the knee, the sartorius turns more laterally as it descends to insert on the medial side ...
Where did Sartorius get its name?
