The RM Pressfit coated with titanium particles is an uncemented elastic monoblock cup made of UHMWPE, representing the advancement of the proven RM Classic Cup system1. With a mean survival rate of 94.4% for aseptic loosening after 20 years2, the RM Classic is one of the most successful uncemented acetabular cups worldwide.
The RM Pressfit cup achieves its primary stability through an equatorial press-fit. Aided by the flattening of the polar region, compressive forces are guided towards the periphery of the acetabular cup.3
The coating comprises a thin layer of non-correlating, individually anchored titanium particles that have no structural stiffness between them.4 This and the elasticity of the UHMWPE material, which is very similar to human cancellous bone5, ensure that the load transfer and the biomechanical behaviour of the cup remain physiological after the implantation, with the aim of preventing stress shielding.6
A high polyethylene thickness of the cup, with a low contact stress, resulting in low wear.7, 8, 9
