Different types of crosslinked UHMWPE are commercially available and are characterised by:

• radiation levels between 50 and 100 kGy,
• stabilisation temperature between 70°C and 160°C,
• final sterilisation with gamma-rays or inert methods (ethylene oxide or gas plasma).

Not all crosslinked UHMWPE provides adequate performance, mainly due to low radiation levels, low stabilisation temperatures and final sterilisation with gamma rays.
Highcross^® by Medacta^® is characterised by:

• radiation at 100 kGy,
• stabilisation temperature of 150°C,
• controlled cooling rate in order to optimise mechanical properties,
• final sterilisation with ethylene oxide.

Such innovative production strategies yield a high quality material with enhanced properties.
Medacta^® has started long term clinical studies to confirm the excellent in vitro and first short-term results.
