This is the company’s initial launch of Logic Porous internationally, with full market availability ramping up throughout 2014 and beyond. Logic Porous is indicated for cemented use only in the US.
Exactech claims that the new porous technology offers knee surgeons a new implant coating that strikes the balance between material strength, pore size and porosity.
Structural lattice of the Logic Porous has been developed through layers of irregular shaped beads, resulting in an increased average pore size and greater porosity than traditional spherical beads.
Exactech CEO David Petty said: "The addition of Optetrak Logic Porous strengthens Exactech’s knee product offerings, demonstrating our continued commitment to providing our surgeon customers with a comprehensive knee system that fits their clinical needs."
The company has also announced that a University of New South Wales animal study comparing the Logic Porous to traditional porous-beaded coating will be first presented at the European Orthopaedic Research Society 22nd annual meeting, 2 July to 4 July 2014.
The animal study used an established ovine model. This study showed greater shear strength at the cortical interface after 12 weeks of implantation and higher overall bone in-growth rates at the cancellous interface after 12 weeks of implantation.
The study has also showed higher total bone in-growth rates at the cortical interface after four and 12 weeks of implantation and greater forgiveness to sub-optimal implantation conditions.
