## Indications for use
The MatryxTM Interference Screw is intended for use in interference fixation of bone - patellar tendon - bone and soft tissue grafts in anterior and posterior cruciate ligament reconstructions. The MatryxTM Interference Screw is not intended for use in and is contraindicated for 1) Insufficient quality and quantity of bone for attachment of graft, 2) Blood supply limitations and/or previous infections, which could retard healing, 3) Foreign body sensitivity to the implant material. Where the material is suspected a test should be made prior to implantation to rule out sensitivity, 4) Patients with active sepsis or infection, 5) Conditions which tend to limit the patient's ability or willingness to restrict activities or follow directions during the healing and rehabilitation period, 6) ACL repairs which would not be appropriate for fixation with metallic screws
