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 bres. The intra-articular longitudinal bres
resist fatigue and allow broblastic ingrowth, the extra-articular woven bres 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.
Use of LARS ligaments allows immediate restoration of knee kinematics by re-centring the knee.
LARS ligaments are used as internal xation devices to aid the healing process.
These ligaments must always be placed in the joint in an anatomical or isometric position.
The diameter of the bony tunnels must correspond to the speci c technique for each type of ligament
and as a general rule should be as small as possible.
LARS can be used for extra-articular reconstructions in tendon repairs such as Achilles tendon,
Lateral Ligament Stabilisation, patella tendon, biceps tendon, rotator cuff etc.
Mechanical in vivo tests for resistance, fatigue and creep have shown that LARS ligaments are highly
effective ligament reconstruction and augmentation devices and mid-term clinical results are excellent.
