on and near anterior superior spine of ilium/medial surface of proximal end of tibia

Sartorius

aids in knee and hip flexion like sitting or climbing, adducts and laterally rotates thigh

Tibialis anterior

lateral condyle and lateral margin of proximal half of tibia/medial cuneiform and MT1

Tibialis anterior
