An implant system has an acetabular cup with an interior bearing surface with a central bearing zone that is smooth and devoid of holes or indentations. The cup also has a peripheral bearing zone that contains insertion tool engagement holes. The engagement holes are only present in the peripheral zone and have specific shapes and dimensions. The system includes an insertion tool with retractable interlocks that fit within the engagement holes to position the cup during implantation. The central bearing zone bears the main forces during articulation, while the peripheral zone withstands minor forces. The location of the engagement holes has a negligible effect on the cup's performance. The cup can be made of ceramic and may have a coated exterior surface for osseointegration.
