Mid-term comparison of highly porous versus hydroxyapatite-coated porous surface in the same cup system: a retrospective single-center study
Both groups demonstrated comparable mid-term clinical and radiographic outcomes. The highly porous group exhibited higher initial RLL incidences. However, RLL diminished over time without compromising the migration or clinical results. Both designs are reliable options for cementless THA.
