Barbed Suture Tendon Repair ASPS

  1. 1. Knotless flexor tendon repair using a barbed suture: An ex vivo comparison. <br />W. Thomas McClellan<br />Matt Schessler<br />David Ruch<br />L. Scott Levin<br />Richard Goldner<br />Kauai HI 2010<br />
  2. 2. Disclosures<br />No disclosures<br />
  3. 3. Hypothesis<br />Knotless flexor tendon repair is as strong as a traditional knot based repair with reduced cross sectional area at the repair site.<br />
  4. 4. Methods<br />66 fresh adult pig FDP tendons<br />3 points established – cross-sectional area<br />1cm proximal, transection site, 1cm distal<br />
  5. 5. Methods<br />Divided into 3 groups, transected, repaired<br />Group A (n=22) – <br />2 strand modified Kessler 3-0 ethibond<br />Group B (n=22) – <br />4 strand modified Savage 3.0 ethibond<br />Group C (n=22) – <br />4 strand Knotless Repair 0 barbed<br />
  6. 6. Knotless Technique<br />
  7. 7. Measured the x-sectional area at all 3 sites after repair and before insitron testing<br />Results – X-Sectional Area(mm2)<br />(p<0.0001)<br />

  9. 9. Results - Strength<br />(p<0.0001)<br />
  10. 10. Summary<br />A 4 strand Knotless repair is as strong as a 4 strand Savage and stronger than a 2 strand Kessler<br />Must maximize # of barbs within the tendon<br />Must incorporate grasps of the epitenon for increased repair strength<br />
  11. 11. Summary<br />Knotless repair has significantly reduced cross sectional area, at the repair site, compared to the Savage and Kessler<br />This may reduce resistance within the pulley system.<br />
  12. 12. Summary<br />however<br />Knotless repair is technically difficult and time consuming <br />Increased handling of the tendon required<br />must place limbs upstream <br />Manipulation of larger core suture is more cumbersome<br />Difficult to remove suture if needed<br />Additional research should be performed to address shortcomings and limitations <br />
