Advanced Surface Technology
Advanced Surface is an innovative coating for knee implants to improve mechanical properties and biocompatibility of knee systems.
The zirconium nitride top coat is characterised by its exceptional surface hardness. The wear rate is reduced by up to 88% compared to standard implants. This ceramic surface layer stands for improved scratch resistance, good wettability and for better articulation between bearing surfaces.
Unlike monolayer coatings, the AS 7-layer coating has a buffer zone which compensates the changes in surface hardness and results in more resilient elastic properties. Additionally the transition layers act as an effective metal ion barrier, thus ideal for patients with metal hypersensitivity.
Beta-PE
All Aesculap knee system’s polyethylenes are sterilized under Beta radiation which uses higher concentrated, lower penetrating radiation levels for reduced oxidation yielding better wear results.
Better long term results
The AS coating in combination with Beta-PE yields superior performance. Better long term results can be expected.
