Abstract

PurposeThe choice of graft type in the anterior cruciate ligament (ACL) reconstruction remains a subject of controversy. The aim of this study was to assess the outcomes in ACL reconstructions performed using a four-strand hamstring tendon graft (4SHG) or a LARS ligament comparing the effectiveness of the two grafts at a medium follow-up of 8 years.MethodsThis retrospective, single-centre, single surgeon study evaluated the clinical, functional and radiographic outcomes in 50 patients who underwent ACL reconstruction (25 4SHG and 25 LARS). Patients who underwent surgery after more than 6 months from injury and showed radiographically visible degenerative changes at time of surgery were excluded from the study.ResultsNone of the patients underwent re-surgery in the same knee. The range of motion of the operated knee, compared to the contralateral, was good for both groups. The anterior drawer test resulted negative in 21 patients (84%) in the LARS group and eight patients (32%) in the 4SHG group (P=0.039). The Lachman test was negative in 19 patients (76%) in the LARS group and in 11 patients (44%) in the 4SHG group (P=0.045). Although other results of ACL reconstruction measured by Lysholm scores, IKDC evaluation, Tegner scores and radiographic images showed using a LARS graft tended to be superior to using a 4SHG, there were no statistically significant differences calculated.ConclusionOur results suggest that 4 years after ACL reconstruction using a LARS ligament or 4SHG dramatically improves the function outcome, while the patients in the LARS group displayed a higher knee stability than those in the 4SHG group.
