LINK Endo-Model EVO is a constrained knee replacement system with rotating-hinge and pure-hinge configurations. Femoral and tibial components form the joint assembly, with standard and modular versions providing different stem connections.
Standard components have fixed stems, while modular components connect to separate stems through tapers. Modular femoral designs include male- and female-taper versions, allowing different reconstruction assemblies within the range.
Listed Item
Femoral component, TiNbN coating, cemented, CoCrMo, UHMWPE, Ti6Al4V, modular, intracondylar replacement, rotating hinge (EVO)
Coating and Stem Options
Rotating-hinge femoral and tibial components are also offered with a PorEx titanium-niobium-nitride coating. Cemented fixation is standard unless a cementless modular stem is specified; the coating and stem choices are configuration-specific features.
