Stryker offers three options among sports medicine interference screws. The patented Universal, Bioabsorbable and Biosteon Wedge Interference Screws are for cruciate ligament reconstruction and indicated for soft tissue and BTB grafts.
The Universal is made of titanium, fully threaded and has blunt threads protecting the graft from laceration.
The Bioabsorbable is made of Poly-L Lactic Acid (PLLA).
The Biosteon, made of 25 percent Hydroxy-Apatite (HA) and 75 percent Poly-L Lactic Acid (PLLA), has the fixation strength of a titanium interference screw and the osteoconductive potential of bone (designed to promote the healing characteristic of the bone tunnel and graft).
