Background

Anterior cruciate ligament (anterior cruciate ligament) injuries are among the most frequent ligament injuries, with autograft reconstruction considered to be the gold standard treatment.

Purpose

The aim of this study was to investigate the biomechanical properties of tape-augmented all-soft-tissue quadriceps tendon construct compared with quadrupled semitendinosus construct (QST) for anterior cruciate ligament reconstruction (anterior cruciate ligament reconstruction) using an established cadaveric biomechanical test protocol.

Methods

A total of nine human cadaveric ASTQTs and 11 QSTs were obtained from the knees of body donors.

n = nine human cadaveric ASTQTs and 11

Results

quadrupled semitendinosus grafts withstood more load before failing

QST

806.1N

ASTQT

577.9N

More results

All ASTQTs exhibited suture tape cut-through (cheese wiring) at the proximal fixation site as their mode of failure.

Conversely, suture rupture was the predominant failure mode in the QST group.

Conclusion · 1 of 2

In an established cadaveric test setting, the QST construct exhibited higher load-to-failure and stiffness compared with the tape-augmented all-soft-tissue quadriceps tendon construct.

Conclusion · 2 of 2

The consistent cheese-wiring failure at the proximal fixation site of the all-soft-tissue quadriceps tendon indicates that the tape-tendon interface-not the substance itself-was the limiting structural element.
