摘要：
Joint resurfacing and/or replacement devices, systems and methods that include thin film ternary ceramic coatings that are effective to provide reliable articulation and bearing surfaces and protection of both articular and modular junction surfaces from the potential for corrosion, wear, and fretting, and reduce the potential for release of metal ions from the joint systems. Isoelasticity is provided according to the particular joint resurfacing/replacement devices, systems and methods based on parameters that include material of construction, porosity and coating system. The thin film ternary ceramic coatings may be functionalized to enhance hydrophilicity and may be employed in any anatomical articulating joint region. Titanium alloy composite structures are provided that include an ultra-porous structured titanium alloy bone fixation surface and an opposed solid articular surface and a thin film ternary ceramic coating applied to one or both opposed surfaces.
