History

More than 25 years ago, the orthopaedic surgeons have faith in the artificial ligaments but their enthusiasm was abruptly stopped as systematic and dramatic failures were observed using synthetic ligaments so often in mechanical, biological and conditioning aspects. At that time, the majority of surgeons has anathematized the artificial ligaments because these implants were not safe.

In parallel if the gains of the ligament surgery using autografts are unquestionable, this surgery also experienced failures complications or disadvantages.

This situation explains why the LARS Company has developed a new and novel artificial ligament by recognizing and addressing the causes of failures and complications of the former artificial ligament.

LARS ligaments are intended for the intra or extra-articular reconstruction of ruptured ligaments to mimic the normal anatomic ligaments fibers. The intra-articular longitudinal free fibers resist fatigue and allow fibroblaste ingrowth, the extra-articular woven fibers provide strength on resistance to elongation.

Indications

Artificial ligaments are non-active implants designed to compensate the loss of natural ligaments due to a trauma or to serve as reinforcement. LARS ligament is a range of synthetic ligament augmentation and reconstruction devices, suitable for a wide variety of applications from knee reconstructions to ankle, hip, hand and shoulder repairs.

For intra-articular ruptures, LARS ligaments can be used in conjunction with the remnants of the acute ruptured ligament or as reinforcement of an autologous reconstruction. In the both cases, LARS ligaments allow the original issues to heal during the immediate post-operative period when an excess of traction would otherwise elongate the tissue.

LARS ligaments can be also used for extra-articular reconstructions in tendon repairs, such as Achilles tendon, gluteal tendon, patellar tendon, quadriceps tendon, biceps tendon, rotator cuff etc…

Other repairs can be envisaged for tumors surgery.
