This study reviewed on stress shielding, which had been reported as one of the main problems that lead to bone loss and revision surgery after implanted in hip joint. It started with a brief discussion on hip joint replacement and detailed discussion on stress shielding phenomenon. It also reviewed currently used of several implant materials and its design in order to reduce the problem. The main intended of this study to set a baseline for conditions of improvement and eradications to the mentioned problem. As the review ended, a lot of studies are required in order to have an implant that may behave like a real joint. Hence, design aspects like stem-bone bonding, the stability of the implant inside the femur and bone reaction along interface, should also give the greatest consideration.
