A biomechanical comparison of techniques of flexor tendon repair

Biomechanical Comparison of Modified Kessler and Running Suture Repair in 3 Different Animal Tendons and in Human Flexor Tendons

“…22 One locking loop was found to be as strong as 2 grasping loops in ultimate load-tofailure testing and gap formation. 28,29,35 In the Kessler technique, the distance of the horizontal core suture from the repair site is of importance (ie, the suture purchase). Several studies suggest a purchase distance of not less than 7 mm and that increasing the distance beyond 10 mm is of no biomechanical advantage.…”

Evaluation of a New 4-Strand Flexor Tendon Repair in a Cadaveric Porcine Model

“…7,8 However, as the complexity of the technique increases, so too does tendon handling and surgical time, potentially leading to increased adhesion formation. 1,3,9,10 Finally, some have suggested that increased suture material may also contribute to adhesion formation. 11,12 The strength of the repair is particularly important as early active motion protocols have become more commonly used.…”

The biomechanical analysis of a tendon fixation device for flexor tendon repair

“…[27][28][29][30] Although many of the proposed suture configurations are high in tensile strength they are technically demanding, require excessive tendon manipulation, and increase the work of flexion. 12,29,31 To meet idealized repair requirements the Teno Fix (Ortheon Medical, Winter Park, FL) has been developed.…”
