Cementless
•One year for good ingrowth
•Up to two years for 100% of
ingrowth bone (30% of the total
porous surface)
90% polymethylmethacrylate (PMMA) 10% Barium Sulfate
Particles from loose cement cause abrasive wear in the acetabular joint
Vacuum mixing decreases voids in the bone cement which decreases stress concentrations within the hardened cement
