For the last 15years,LARS has been used with very good results, with earlier mobilization.Depending on surgeons skill and experience, it would be preferable against hamsting.For your information I am pasting the comparisan below--
SYNTHETIC (LARS ligament)
Extreme loading capacity without elongation;
Rapid in growth of fibroblast(healthy tissue);
Absolute tissue tolerance;
Rapid recovery 6-8 weeks (no long period of immobilization required);
No muscle atrophy;
No cases of reactive synovitis(effusion of joint) or of infection;
No risk of weakening the joint (since no anatomical material is taken);
Replacing of a synthetic ligament is as easy as its initial installment.
AUTOGENOUS(
Hamstring) (from patient)
Long period of immobilization required;
Chances for Muscular atrophy;
Long period of revascularization;
Limitation of graft in case of revision;
Long phase of therapy for a good rehabilitation;
Full sports are generally authorized after 6 months.
