INTRAFIX® is a two-part polyethylene system with a screw and expandable sheath, designed and patented to provide strong and stiff intra-tunnel fixation.
The INTRAFIX fastener offers an expanded size selection and line-to-line sizing. It also features a patented screw and sheath design that enhances bone-to-graft contact and strength through:
Tested in human cadaver bone, the INTRAFIX system demonstrated excellent fixation, with >1000N pull-out strength1. Tested in an independent study (against five other tibial soft tissue fixation systems), INTRAFIX demonstrated the highest strength and stiffness with the lowest graft displacement.1
