Interference Screws

Arthrex Interference Screws are of the highest quality standard that have become synonymous with the Arthrex name. A complete family of interference screws includes Bio-Interference Screws (primarily amorphous PLLA Full Thread), BioComposite Interference Screw (comprised of 30% biphasic calcium phosphate and 70% PLDLA), PEEK Interference Screws, (made from PEEK-OPTIMA® from Invibio®), Metal Interference Screws (made from titanium for femoral and tibial fixation of a soft tissue or bone-tendon grafts in cruciate ligament reconstruction procedures), and Sheath Cannulated Screws (translucent sheath).

FastThread™ Interference Screws
BioComposite FastThread interference screws are designed with a prominent leading and large thread pitch to facilitate screw engagement and advancement. Optimized screw threads improve pullout strength vs longer screws of the same diameter.1 Vented sidewalls and screw geometry decrease material by 22% without losing insertion or fixation strength.2,3 Arthrex’s proprietary biocomposite material has withstood the test of time with more than a decade of clinical use and millions of implantations.4 Rounded thread and head design may reduce damage to graft on insertion and cycling. Fewer screw heads reduce turns, twisting, and possible graft abrasion. The 20 mm screws are packaged with an insertion sheath.
GraftBolt® Sheath and Screw
Designed for tibial fixation of a soft-tissue graft in cruciate ligament reconstruction procedures, the all-PEEK GraftBolt implant comprises a fully cannulated sheath and mating screw. The GraftBolt instrument set includes dilators, sheath insertion and removal tools, and a hexalobe driver for screw insertion.
Metal Interference Screws
Arthrex offers the most comprehensive variety of titanium interference screws for knee ligament reconstruction. The cannulated interference screws are available with a full thread design for maximum cortical fixation, or with a rounded head for protection of the graft on the femoral side. Sheathed cannulated interference screws come packaged with a translucent sheath that facilitates passage of the screw through the portal, protects the graft during screw insertion into the tunnel and allows for simplified removal of the screw if needed. The soft screw is specially designed for use with soft tissue grafts. The smooth, blunt threads and round head of the soft screw protect the graft from laceration on insertion and with range of motion of the knee. All metal screws and screwdrivers are cannulated to accept a sturdy 2 mm Nitinol Guide Pin to reduce divergence during screw insertion. Arthrex Guide Pins are marked at 25 and 30 mm to confirm proper depth during wire and screw placement.
