What is the rectus femoris muscle?

Rick Olderman
Physical Therapy

One of the muscles that influences how well the pelvis and knee function is the rectus femoris, one of the thigh muscles that are also referred to as the quadriceps muscles. It crosses the hip joint, originating just below the tensor fascia lata (TFL), and inserts onto the kneecap along with all the other quadriceps muscles. When it's tight, it can cause the pelvis to tip forward (anterior pelvic tilt), which accentuates the effects of a tight TFL. In addition to knee and hip pain, these muscles are also implicated in back pain. The rectus femoris may also contribute to an abnormal resting position of the kneecap.
