Three-compartment knee prosthesis SCORE® AS

mobile-bearingcemented or non-cemented

SCORE® AS (Allergy Solution) is a primary total knee arthroplasty implant with the same mechanical features as the SCORE® TKA implant. Stability through congruency PCL-sacrificing Titanium nitride (TiN) coating The SCORE® AS (Allergy Solution) has the same mechanical features as the SCORE® TKA implant. The 4 µm thick titanium nitride (TiN) layer will prevent release of up to 90% of sensitising metal ions. TiN is four times harder than standard cobalt-chrome and has excellent biocompatibility. The 4 µm TiN coating is applied by physical vapour deposition (PVD). Electric arc material (Ti) vaporised from a target (cathode) Vaporised Ti condenses on the implant surface (anode), resulting in the formation of a thin layer Nitrogen gas introduced into chamber binds to the Ti
