The Biomechanical Properties of a High-Tensile Strength Tape for Tendon Graft Fixation Using the Krackow Configuration.

ABSTRACT:

Purpose

To compare the biomechanical properties of a high-tensile strength suture with the high-tensile strength tape for tendon graft fixation.

Methods

A total of 24 porcine tendons were used and were randomly divided into 2 groups. Two kinds of suture materials, a braided nonabsorbable high-strength suture (group S) and a high-tensile strength tape (group T), were used to complete 3 pairs of Krackow stitches on the tendons. Each specimen was pretensioned to 100 N for 3 cycles, cyclically loaded from 50 to 200 N for 200 cycles, and finally loaded to failure. Elongation after cyclic loading, ultimate failure load, and the mode of failure were recorded.

Results

The elongation after cyclic loading between group S (26% ± 5%) and group T (24% ± 5%) were not significantly
