Renovis MAX™ Acetabular Inserts Benefits

Hip Product Group

Renovis MAX underwent extensive laboratory evaluations, including
wear simulator testing.

Excellent wear properties

Renovis MAX demonstrated 95% less wear than conventional polyethylene. [1]

Hip Simulator Wear. 40 mm heads and liners.

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]  Renovis MAX acetabular inserts are available for use with heads up to 40 mm in diameter.
