Evolution® NitrX™ Knee System

The Evolution® NitrX™ medial-pivot knee features a titanium niobium nitride (TiNbN) coating that has been shown to reduce the release of cobalt (Co), chromium (Cr), nickel (Ni), and molybdenum (Mb) ions common in standard CoCr implants.1  The Evolution® NitrX™ knee maintains the kinematic benefits of the medial-pivot design2, resulting in optimal stability.5
