DePuy Mitek Launches BIO-INTRAFIX(TM), the Latest Innovation in ACL Repair -- Soft Tissue Tibial Fixation

    NORWOOD, Mass., June 24 /PRNewswire/ -- DePuy Mitek, Inc., a leading
 manufacturer of surgical sports medicine devices, announced today the launch
 of the BIO-INTRAFIX Soft Tissue Tibial Fixation System.  BIO-INTRAFIX is the
 next-generation of soft tissue tibial fixation for Anterior Cruciate Ligament
 (ACL) repair; combining the proven success of the INTRAFIX system, DePuy
 Mitek's leading ACL repair product for over five years, with the bioabsorbable
 BIOCRYL(TM) material, comprised of osteoconductive TCP and bioabsorbable PLA.
     BIO-INTRAFIX was developed to address the growing trend in the use of soft
 tissue grafts in ACL repair procedures (replacing the torn ACL with a
 hamstring tendon graft harvested from the patient) as an alternative to the
 widely used bone-tendon-bone patella tendon repair.
     "In 1998, 20 - 30 percent of the ACL repair procedures I performed were
 done using soft tissue tibial fixation, today that number has increased to 80
 percent," said John C. Richmond, M.D., Chairman of Orthopedics at New England
 Baptist Hospital in Boston, MA.  "This increase is due in part to the benefits
 provided by the soft tissue procedure over the bone-tendon-bone procedure;
 including smaller incisions resulting in smaller scars, the potential for a
 shorter rehabilitation time, as well as less kneeling pain."
     The new BIO-INTRAFIX System was created based on DePuy Mitek's INTRAFIX
 System, which has a successful history of clinical use since 1999.  The BIO-
 INTRAFIX system consists of two bioabsorbable (TCP/PLA) components: the
 expansion sheath, and the tapered screw; both molded from BIOCRYL material, a
 composite of PLA and osteoconductive TCP (Tricalcium Phosphate). *  Both
 systems achieve fixation by placing the expansion sheath into the tibial
 tunnel between the soft tissue graft strands and then inserting the screw into
 the sheath.  The system compresses the graft against the tunnel and due to the
 design of the expansion screw, engages the cortical wall at the distal end of
 the tunnel creating strong, rigid fixation.  In one study, the BIO-INTRAFIX
 system produced pullout strength of 1067N (the amount of force it would take
 for a screw to pull out of bone), equivalent to/better than bone-tendon-bone
     "I have been very impressed with BIO-INTRAFIX and I will continue using it
 for my soft tissue tibial fixation procedures," said Dr. Joseph H. Sklar,
 M.D., from New England Orthopedic Surgeons in Springfield, MA.
     BIO-INTRAFIX is indicated for fixation of soft tissue grafts during
 cruciate ligament reconstruction.  The BIO-INTRAFIX screw is available in
 three sizes; 6-8 x 30mm, 7-9 x 30mm and 8-10 x 30mm.  Additional information
 on BIO-INTRAFIX and the BIOCRYL material is available at
