Product Overview
 -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
Focus on rapid recovery:
-Metal sensitivity has been linked to metallic debris 
 and metal ions, namely cobalt, chromium, and nickel. 
 The Evolution® NitrX™
 medial-pivot knee has been shown in simulated clinical 
 testing to reduce the release of these metal ions1, and 
 builds upon the same medial-pivot legacy of 95% 
 patient satisfaction with 98.8% survivorship at 17 
 years.3
Additional NitrX™ Features
Additional features of the NitrX™ coating
• Increased hardness and wettability1,4
• Excellent wear properties4
• High corrosion resistance6-9
• Excellent Biocompatibility1,4
Reduce the release of specific metal ions while promoting natural kinematics:
-The Evolution® NitrX™ knee features a titanium 
 niobium nitride (TiNbN) coating, which creates a 
 barrier against the potential release of metal ions 
 common in cobalt chrome (CoCr) implants.1 Since 
 metal sensitivity in patients is linked to metallic debris 
 and metal ions, namely cobalt, chromium and nickel, 
 preventing that debris from interacting with soft 
 tissue may have a benefit of reducing the incidence of 
 tissue reactions.11,12
