The fatigue resistance of our implants is the most advanced to date, thanks to the use of free fibers, particularly on the Z-lig, which still retains 90% of its initial strength after 12 million cycles.
In fact, loose fibers are designed to resist bending, tension and, above all, torsion.
But that’s not all: the highly porous architecture of free fibers offers another advantage: they are colonized by fibroblasts, enabling the creation and development of neo-collagen within them.
The images below are cross-sections from a histological study carried out 1 year after surgery on a dog (transverse and longitudinal sections).
It can be clearly seen that the free fibers provide an environment conducive to fibroblast invasion, initiating regeneration of the native ligament (when a residue exists and is preserved).
The same applies to L-ten, whose free fibers must be placed at the level of the rupture zone to enable regeneration of the ruptured tendon.
