Soft Tissue Internal Fixation

Vetlig’s Background in human medicine


The 1980s saw a growing enthusiasm for synthetic material ligament reconstruction, by the 1990s the popularity of artificial implants had declined due to high failure rates. The ligaments of the first generation were extremely brittle, ruptured early, shed lubricants or were not resistant to abrasions causing synovitis. Although the newer synthetic ligaments of the second generation were a marked improvement over the previous ones, they also caused early failures due to a lack of tissue in-growth and low resistance to abrasion and fraying.

The Vetlig ligament represents a fourth generation synthetic ligament. It incorporates a design, which takes into account the causes of earlier synthetic ligament failures, it has been developed with a more accurate understanding of the functional anatomy of joints, muscle-tendon units and ligaments.

It is the most advanced non-biological soft tissue treatment option. It gives immediate strength, optimised function, conservative anatomical restoration and rapid recovery.

It has been designed by a human orthopaedic surgeon in collaboration with vets worldwide and the whole company has over 25 years experience in human and veterinary orthopaedics.


The ligament is made from UHMWPE ( ultra high molecular weight polyethylene ) fibre In contrast to previous generation synthetic ligaments these are extensively treated to remove residual processing aids, which were found to inhibit soft tissue in-growth, providing a more fibroblastic friendly environment. The intra-articular portion of the ligament consists of longitudinal fibres without transverse or crossing components.

Vetlig reflects a fourth generation of ligament design
The free fibres are oriented to the ligament they are intended to be used with, mimicking the normal anatomic fibres. This structure allows a high resistance to fatigue, especially in flexion, as well as providing a porosity favouring fibroblastic ingrowth, which then isolates the synthetic fibres.

Regardless of the tissue or implant used for cruciate reconstruction, all are avascular at the point of implantation, this is why preserving any native remnants and the free fibres of vetlig, encourage fibroblastic in-growth and graft remodelling, without compromised mechanical strength during the initial healing phase.


  • Providing immediate strength and stability to the repair
  • No ligament deformation even up to loads of 140 newtons at 90 degrees of torsion for 2 million cycles, per fibre. This equates to over 6000 newtons for a 48 fibre ligament.
  • No ligamentisation period
  • Fixation with titanium interference screws


  • Free-fibre designs used in a variety of indications
  • Stifle, patellar, achilles, shoulder hip and tumour applications
  • Conservative anatomical restoration
  • Refined surgical techniques and instrumentation


  • Faster rehabilitation and return to activity
  • Conservative approach, no altering of the biomechanics of the knee
  • Early mobilisation
  • Novel fibre treatment process facilitates excellent tissue in-growth
