Intra-articular reconstruction of cranial cruciate ligament
The rupture of the cruciate ligament is the main cause of orthopedic consultations in dogs. This condition is often treated with relatively traumatic osteotomy techniques or extra-articular stabilization, which do not fully restore all the functions of the torn ligament.
NOVALIG® is a synthetic ligament that replaces the ruptured ligament thanks to its perfectly isometric implantation, restoring the biomechanics of the stifle and all mechanical functions.

F.A.Q.
What information do we have on the intra-articular use of UHMWPE synthetic fiber ?
UHMWPE fibers have been used in intra-articular human and veterinary orthopedic surgery for several decades. They are a perfectly biocompatible inert material. Significant experience is now available on its tolerability for intra-articular use in both humans and dogs. 1. E. Soreide, J.M. Denbeight et al.

What is the benefit of intra-articular reconstruction ?
The stifle joint is extremely complex and its stability is highly dependent on its numerous ligaments. Although they provide highly satisfactory clinical results, extra-articular osteotomy or stabilization techniques only partially address the mechanical problems associated with the rupture of the cranial cruciate ligament.
Intra-articular reconstruction is the technique with the closest possible outcome to a healthy knee.
It is also the only technique that can be performed arthroscopically. It offers a minimally invasive solution with reduced tissue trauma and associated pain, faster surgery, lower anesthetic risk and reduced use of painkillers.
Why use interference screws for fixation ?
Interference screws provide immediate, atraumatic fixation for the implant and are fully fixed in the bone. They reduce the risks of irritation and early laceration thanks to a large knot.
The mechanical resistance of this type of fixation has made it a gold standard in many human medicine applications.
