Manufactured from medical-grade PEEK (Polyether Ether Ketone), the screw offers high mechanical strength, biocompatibility, and radiolucency, allowing clear postoperative imaging without metallic artefacts. The thread design facilitates controlled insertion and optimal graft compression, supporting stable fixation under cyclic loading conditions. Available in diameters ranging from 6 mm to 11 mm and lengths from 20 mm to 35 mm, the implant accommodates varying tunnel sizes and graft configurations in ACL and related ligament reconstruction procedures.
