About this product

Division: Hip Reconstruction
Category: Acetabular Solutions

MARATHON Polyethylene was the first FDA-cleared, third generation, crosslinked polyethylene which reduces wear versus non-crosslinked polyethylene, while resisting oxidation and maintaining mechanical standards2,6. MARATHON is produced from GUR 1050 polyethylene ram extruded bar that is moderately crosslinked at 5 Mrad of gamma irradiation, then stabilised using a patented remelting process to eliminate free radicals balancing the need for wear resistance against the damaging effects of irradiation1.
