To determine, through finite element simulation (FEM), the adaptation of the posterolateral (PL) fascicle fixation by means of a biocompatible screw for anterior cruciate ligament (ACL) repairs when using the bifascicular technique with a single tibial tunnel.
Material and method
It has been performed a finite element study in order to analyse the stress suffered by both material fixation (Endobutton® and Biosure HA®), and the bone component in ACL repairs using the bifascicular technique with a single tibial tunnel.
The simulation carried out shows that the forces exerted over the fixations and the bone are within the allowable limits for the bone and the manufacture material of the fixing devices, both at the anchorage area and at distal femur.
The fixation of the PL fascicle by means of a biocompatible screw Biosure HA® in ACL repairs, when using the bifascicular technique with a single tibial tunnel, allows ensuring a proper mechanical behaviour when patient's knee is going to be intensively rehabilitated.
