Artificial ligaments are non-active surgical implants designed to compensate the Ioss of natural ligaments (must often due to a trauma) or to serve as reinforcement.
LARS is a range of synthetic ligament augmentation and reconstruction devices, suitable for a wide variety of applications from ACL and PCL reconstruction to ankle and shoulder repairs.
LARS ligaments are intended for the intra or extra-articular reconstruction of ruptured ligaments, designed to mimic the normal anatomic ligament fibers. The intra-articular longitudinal fibres resist fatigue and allow fibroblastic ingrowth, the extra-articular woven fibres provide strength and resistance to elongation.
LARS ligaments can be used in conjunction with the remnants of the ruptured ligament, or as reinforcement of an autologous reconstruction. In both cases, LARS ligaments allow the original ligament tissues to heal during the immediate post-operative period, when an excess of traction would otherwise elongate the tissue.
LARS ligaments can be used for extra-articular reconstructions intendon repairs such as Achilles tendon, patella tendon, biceps tendon, rotator cuff etc… Other repairs can be envisaged as tumours surgery.
History and clinical performance
Twelve or fifteen years ago, the surgeons have faith in the LARS ligaments but the enthusiasm for artificial ligaments was abruptly stopped as the long term behavior and safety of the artificial ligaments were assessed.
It is clear that systematic and dramatic failures were observed using synthetic ligaments so often in mechanical, biological and conditioning aspects.
At that time, the majority of surgeons have anathematized against the artificial ligaments and seemed to forget that many new and novel surgical procedures, have also experienced several difficulties and detractors.
From a historical perspective, it has been proved many times that it is possible to get the better of inquisitive scientists.
If the gains of the ligament surgery using autografts are unquestionable, this surgery also experienced failures, complications or disadvantages but it does justify that we do make progress.
Currently, as the second generation of artificial ligaments, the LARS ligament made great progress on both biological and mechanical aspects. However, despite these progresses, the performances of the artificial ligaments cannot be compared to those of the natural ligaments.
The analysis of the failures of the artificial ligaments led to codify better surgical techniques and especially the indication which is the sole responsibility of the surgeon in agreement with the patient. The good indication, the experience of the surgeon and the patient motivation are indeed the key requirements of a successful surgery.
For nearly 20 years, about 100,000 LARS ligaments have been used around the world with results more and more satisfactory over the years. Numerous publications attest this success which is the result of your joint work. LARS Company is very grateful to the surgeons community. LARS Company is very proud that the scientific authorities recognize today the existence of LARS ligament as a part of the therapeutic arsenal of the arthroscopic surgeons for specific indications.
The quality of the published results consolidates the achievements and leads to an undeniable legitimacy.
