MAX underwent extensive laboratory evaluations, including wear simulator testing.
Excellent wear properties
MAX demonstrated 95% less wear than conventional polyethylene. [1]
Stability with large diameter heads
Larger diameter heads have been shown to lead to improved range of motion and lower dislocation rates. [2,3,4,5] MAX acetabular inserts are available for use with heads up to 40mm in diameter.
