Exactech, Inc., a developer and producer of bone and joint restoration products for hip, knee, shoulder, spine and biologic materials, announced the international launch of Optetrak Logic Porous, a new porous technology for total knee arthroplasty.
Logic Porous offers knee surgeons a new implant coating that strikes the balance between material strength, pore size and porosity. Its unique structural lattice developed through layers of irregular shaped beads results in an increased average pore size and greater porosity than traditional spherical beads.1
A University of New South Wales animal study compared the Logic Porous to traditional porous-beaded coating. 1 The animal study, which used an established ovine model, demonstrated: greater shear strength at the cortical interface after 12 weeks of implantation; higher overall bone in-growth rates at the cancellous interface after 12 weeks of implantation; 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. The study will be first presented at the European Orthopaedic Research Society 22 nd Annual Meeting July 2-4.
“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,” Exactech CEO David Petty said.
The launch coincides with the 20 th anniversary of the Exactech Knee, a clinically-recognized system of proven implants and personalized surgical techniques, which includes the Optetrak lineage of implants and ExactechGPS Guided Personalized Surgery. This is the 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 U.S.
