Abstract:
Objective To evaluate the effects of 4 different epitendinous sutures on the tensile strength of the repaired tendons. Methods 40 plantar flexion deep tendons from pigs were divided into 4 groups randomly, with 10 in each group. After the core suture of Modifier Kessler was applied, 4 epitendinous sutures at different distances from suture sites to broken ends (4mm, 7mm, 10mm, 12mm) were used respectively in each group to repair the transected tendons. MTS Instron 4411 was used to test the repaired tendons. Tensile strengths at 2mm gap formation and at the peak were collected for statistical analyses by ANOVA. Results In this test, the tensile strength was found to increase with the distance from suture sites to broken ends. The tensile strength in the 4mm group was significantly lower than that in the others. There was little statistical difference between the other 3 groups. Conclusion Tensile strength of the repaired tendon tends to increase with the distance from suture sites to broken ends in epitendinous suture.
