The iFix Interference Screw System was the first self-tapping polyetheretherketone (PEEK) interference screw developed for bone-patellar tendon-bone ACL reconstruction procedures. The interference screws are manufactured using PEEK-OPTIMA®, a non-absorbable polymer that is highly biocompatible, biomechanically strong and radiolucent with decades of proven orthopedic success. With this material and key design features for easy implementation, this technology provides a solution to surgeons and accommodates all types of pathologies and patient needs with multiple sizes.
