Hip adductors

The hip adductor muscles originate along the pubic ramus and ischial tuberosity. Three of them insert on the medial aspect of the femur at various points from near the pubis to near the knee. Gracilis is the only one that also crosses the knee joint, inserting near the tibial condyle. Trigger points in these muscles refer pain mostly over the anterior and medial aspects of the thigh.

Translation: The name "adductor" means "toward-puller." "Magnus" means "big," "longus" means "long," and "brevis" means "short." These muscle on the inner thigh have the job of pulling your leg toward the center, or pulling your legs together. At one end they attach all along an arch of bone that goes from your pubic bone down and back to your "sitbones." At the other end, three of them attach at various points along the inner part of your thighbone. The fourth, gracilis (which means "the slender muscle"), crosses your knee and attaches near the inner knob at the top of your lower leg. Trigger points in these muscles can cause pain along your inner thighs and the fronts of your thighs.
