Total joint replacement is accepted as one of the most revolutionary procedures not just in orthopedics, but in whole medicine. With better healthcare, patients with replaced joints live longer, which causes more surgical revisions. Advances in both component design and material composition try to fulfill the increasing demand of younger and more active patient population. It should be remembered that even the most advanced component should be applied with proper biomechanical and surgical techniques. A balance between implant stiffness and flexibility must be obtained according to patient`s expectations. Newer and more advanced designs need not be the ideal choice for every patient. Proper indication and convenient material choice are the most important issues in total hip arthroplasty, especially in the selection of acetabular component. Nowadays, cementation is mainly used in patients above 65 years of age with compromised bone quality, while on the other hand uncemented prostheses are preferred for younger and more active patients with good bone quality. New component designs aim lower friction and decrease of wear. New porous materials stimulating bone ingrowth are introduced to enhance bone-implant integration. This paper focuses on ideal acetabular component designs and new advances to achieve good fixation, low wear on bearing surfaces, adequate stability and high range of motion.
