Summary Statement

We evaluated the mechanical strength of two cortical suspension devices by reproducing clinical situation for ACL reconstruction. A most important factor affecting the displacement during cyclic load was the length of the tendon rather than the length of the device.

Introduction

A definite consensus for the optimal graft fixation technique to the femur in an anterior cruciate ligament (ACL) reconstruction has not been reached, although there have been several fixation techniques such as cortical suspension devices, transfixation devices, and interference screws. The purpose of this study was to evaluate the mechanical strength of two cortical suspension devices by reproducing actual clinical situation for ACL reconstruction in order to compare the TightRopeTM as a new adjustable-length loop device and the EndoButtonTM as a well-known fixed-length loop device under the consistent conditions.
