Abstract:
Acetabular pressfit fixation depends on rigid initial fixation, subchondral bone preservation, and close apposition to allow biologic interface incorporation. A hemispherical cup with a 1 to 2 mm pressfit offers optimal fixation and adjunct fixation with screws or pegs appears to be limited. Pressfit continues to be the ideal fixation choice for most patients.
