anteriorly and superiorly by iliofemoral ligament to prevent hyperextension. It attaches to the anterio inferior iliac spine, margin of the acetabulum and the intertrochanteric line

anteriorly and inferiorly by the pubofemoral ligament to pevent overabduction. It is attached medially to the iliopubic eminence and superior pubic rami and laterally to the intertrochanteric line of the femur. Laterally it blends with he fibrous membrane and with the deep surface of the iliofemoral ligament

Posteriorly by the ischiofemoral ligament. It is attached medially to the ischium and laterally to the greater trochanter deep to the iliofemoral ligament
