US-based orthopaedic implant device provider Exactech has launched its Optetrak Logic Porous for total knee arthroplasty.

US-based orthopaedic implant device provider Exactech has launched its Optetrak Logic Porous for total knee arthroplasty.

Internationally, this is the company's initial launch of Logic Porous, with full market availability ramping up throughout 2014 and beyond.

The company said that the Logic Porous is indicated for cemented use only in the US.

Logic Porous provides knee surgeons with a new implant coating that strikes the balance between material strength, pore size and porosity.

"The animal trial used an established ovine model and 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 structural lattice of Logic Porous is developed through layers of irregular shaped beads, which results 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."

According to the company, a University of New South Wales animal trial compared the Logic Porous with traditional porous-beaded coating.

The animal trial used an established ovine model and 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.

In addition, the trial 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.

The study was first presented at the European Orthopaedic Research Society 22nd annual meeting, 2-4 July.
