Corin Australia surpasses 23,000 case milestone for LARS™ ligament and tendon reinforcement

• Over 23,000 LARS ligaments have been implanted in ASPAC since 2004
• Over 10,000 LARS ligaments were used in extra-articular procedures
• LARS ligaments are used in combination with native and donor tissue to provide additional tensile strength while minimising excessive stretch and laxity

SYDNEY, AUSTRALIA, March 11, 2021

Corin Australia, a global orthopaedic company, have distributed the Ligament Augmentation and Reconstruction System (LARS) in ASPAC for nearly 20 years. In that time, more than 23,000 LARS ligaments have been implanted by over 600 surgeons. Globally, more than 100,000 LARS ligaments have been implanted since their invention in the early 1990’s in Dijon, France.

The LARS range offers over twenty products, providing unique augmentation options for numerous upper and lower limb indications. Given the degree of variability in human tissue, LARS ligaments are designed to be used in combination with native or donor grafts as a biocompatible reinforcement. They aim to minimise stretch, and resultant laxity and instability, by enhancing tensile properties to create a more robust construct to resist forces acting on affected joints.

More than 120 journal articles have been published on the LARS ligament, making it one of the most researched, and published augmentation devices. Ebert et al 2020, found significantly improved clinical and functional outcomes, high levels of patient satisfaction, and a relatively low failure rate up to 24 months post-surgery in gluteal tendon repair with LARS augmentation¹.

Porter et al 2019, reported better Foot and Ankle Outcome Scores (FAOS) at five years and higher Tegner activity scores compared with the Modified Broström-Gould (MBG) procedure in physically active patients with chronic lateral ligament instability².

In the upper limb, investigating LARS use in ACJ reconstruction, UK and European authors found a failure rate of 2% at 2-year minimum follow-up³ and good-to-excellent clinical and functional outcomes at a mean of 7.4 years follow-up⁴.

In cruciate reconstruction ACL graft reinforcement, a Western Australian research group observed comparative side-to-side limb laxity measurements with a low rate of secondary ipsilateral and contralateral ACL ruptures⁵.
