To know, you first need to know the landmarks of anterior and posterior on the femur itself. The lia aspera is on the back of the shaft (a long raised ridge that runs down the back of the shaft). If the femur is facing you and there is no lia aspera then you see the anterior of the femur and the head of the hip will point to the opposite side. So if the hip ball is pointing to the right then that is the left hip and vice versa.
