Ligament Augmentation & Reconstruction System

LARS™ ligaments are available for use in the following applications:

LARSLARS™ ligaments are intended for the intra- and extra-articular reconstruction of ruptured ligaments, various tendons, large muscle defects and can even be used as a bare prosthesis following major traumatic incidences or tumor surgery. LARS™ can be used in conjunction with suturing to the remnant of the ruptured ligament, or in conjunction with an autogenous reconstruction with both intra-articular and extra-articular reconstructions. In both cases, LARS™ allows the original ligament tissues to heal in the absence of traction.

Intra-articular ligaments must always be positioned in the most functionally isometric position possible, because unlike native structures or autologous graft material, its elasticity is limited. The diameter of the bony tunnels must correspond to the specific reference for each type of ligament and as a general rule, should be as small as possible to encourage bony tissue in-growth. The artificial ligament should be placed in the centre of the remnant of the native ligament or attached to the stump of a tendon.

Biological and mechanical testing of resistance, fatigue and creep have shown that LARS™ ligaments are highly effective ligament reconstruction and augmentation devices, and long-term clinical results are excellent. The use of the LARS™ artificial ligaments may require a specific surgical technique. Dedicated LARS™ instruments are available where this is the case.

Knee soft tissue repair/reconstructions

  • Acute and chronic ACL-repair*
  • PCL with or without postero-lateral corner repair
  • Augmentation of a biological reconstructed tendon
  • Medial and lateral collateral ligament repair
  • MPFL ligament
  • Patella tendon repair and re-alignment
  • Quadriceps tendon repair
  • Hamstring tendon repair

* LARS™ should not be used intra-articularly to repair a ruptured ACL without having a vital and well vascularised stump - if the ACL remnant tissue is degraded or the notch is empty, an autogenous graft should be used in conjunction with the LARS™.

Shoulder and arm soft tissue repair/reconstructions

  • Acromio clavicular dislocation**
  • Major rotator cuff repair
  • Biceps tendon repair
  • Triceps tendon repair
  • Wrist reconstruction

Foot and ankle soft tissue repair/reconstructions

  • Acute and chronic Achilles tendon repair
  • Repair of lateral instability of the ankle
  • Repair of medial instability of the ankle
  • Repair of the talus-calcaneum joint 
  • Various tendon repairs and augmentation

Hip soft tissue repair/reconstructions

  • Prevention of hip instability after total hip replacement
  • Abductor mechanism repair
  • Short external rotator repair (SER)
  • Hip revision surgery 

Tumour and complex soft tissue repair/reconstructions

  • Reconstruction of the quadriceps extensor mechanism
  • Reconstruction of the patella extensor mechanism

  • Augmentation of a biological reconstructed tendon

Important: LARS™ is not available or cleared for distribution in all international markets. For more details, please contact your local subsidiary or distributor by visiting the Corin worldwide section of the Corin Group corporate website.
