Outcome of anterior cruciate ligament reconstruction using synthetic grafts (LARS and ABC)
Abstract
Background: Graft choice for anterior cruciate ligament (ACL) reconstruction is of critical importance. Various grafts have been used so far, with autografts long considered the optimal solution for the treatment of ACL-deficient knees. Limited data are available on the long-term survivorship of synthetic grafts.Purpose: To compare the functional outcome and survivorship of ACL reconstructions performed using the LARS (Ligament Augmentation and Reconstruction System) ligament and the ABC (Active Biosynthetic Composite) purely polyester ligament.Study Design: Case series; Level of evidence, 4.Methods: The results of 72 patients who underwent primary arthroscopic ACL reconstruction with the LARS ligament and 31 cases with an ABC purely polyester ligament were reviewed. The mean follow-up for the LARS and ABC groups was 9.5 years and 5.1 years, respectively. A survivorship analysis of the 2 synthetic grafts was performed using the Kaplan-Meier method with a log-rank test (Mantel-Cox, 95% ...
