A Novel Method for Reducing Gap Formation in Tendon Repair
Background: This study investigates gap formation in tendon repair using a novel tensioning method. Hypothesis: The novel stitch will demonstrate less gap formation than the other suture configurations tested. Methods: Porcine tendons stitched with classic Krackow stitch configurations were compared to a Krackow stitch modified with a proximal Tension-Assist Loop. Each group was cyclically loaded followed by analysis of the tendon-suture construct for gap formation. Results: The Tension-Assist Loop group produced significantly less gap formation than each of the other stitch groups. Conclusion: Decreasing early gap formation may be beneficial in allowing early rehabilitation and range of motion.
