Zimmer's CSTi Porous Coating has more than 15 years of clinical experience with demonstrated success in both retrieval and long-term clinical studies.
Optimal Microstructure and Material Promote Bone Ingrowth
CSTi Porous Coating combines the excellent biocompatibility of titanium with an optimal structure for bone ingrowth. Its porous coating is manufactured through a proprietary process that sinters commercially pure titanium powder onto a titanium- or CoCr-alloy substrate. During the process, pores are created. This results in a unique porous coating that has optimally sized, interconnected pores to allow bone ingrowth and a fine micro-roughness to provide secondary fixation.
CSTi Coating is sintered onto the substrate at high temperature, resulting in a solid solution at the interface of the substrate and the CSTi Coating. This results in excellent strength and cyclic fatigue properties.
Cancellous-Structured Titanium Coating refers to the microscopic appearance of CSTi Porous Coating. CSTi Coating is structurally similar to human cancellous bone and provides interconnected pores for bone ingrowth.
We offer CSTi Porous Coating options with several of our product lines, including: the Natural-Knee® II System, Natural-HipTM and APR ® Hip Stems, and Converge® CSTi Porous Acetabular Cup System components.
The CSTi process was originally developed for application on a titanium-alloy substrate. The SinterlockTM Bonding Process was later devised to apply CSTi Coating onto CoCr-alloy femoral knee components. This bimetal combination was a major advancement that combined the biocompatible properties of CSTi Coating on the bone-contacting side of the implant with the excellent wear properties of CoCr for the articulating surface.
