Ischial tuberosity to head of fibula and lateral condyle of tibia.
Common tendon with semitendinosus from superior medial quadrant of the posterior portion of the ischial tuberosity.
The main attachment is to the styloid process of the fibula, forming a semicircle around the lateral collateral ligament. The remainder splits into three laminae: the intermediate lamina fuses with the lateral fibular collateral ligament, the others pass superficial and deep to the ligament to attach to the lateral condyle of the tibia.
