Comparison Of Early Clinical Outcome Of ACL Reconstruction Of LARS Artificial Ligament And Autologous Hamstring Tendon

Objective: To compare the ACL single bundle reconstructions with autogenous four-strand hamstring tendons,early clinical outcome of using the LARS artificial ligaments in anterior cruciate ligament (ACL) deficient knee were studied retrospectively.Method: Forty cases of ACL injury were studied from January 2007 to December 2008.According to the indication of LARS ligament reconstruction,surgeon's suggestion and patient's aspiration,LARS artificial ligaments or autogenous hamstring tendons were chosen as grafts. Eighteen cases with the LARS artificial ligaments were fixed by screw,and twenty-two cases with autogenous hamstring tendons were fixed in formal tunnel by endobutton and in tibia tunnel by BioRCI-HA-Schraube screw. Each patient was evaluated with Lysholm score pre-operative,3 months postoperative,6 months postoperative,9 months postoperative .espectively.Results: Compared with the cases using autogenous hamstring tendons ACL reconstruction, the cases using the LARS artificial ligaments had higher score in the evaluation of knee functions within 9 months follow-up postoperative.Conclusion: The knee function scores are raised in cases using the LARS artificial ligaments ACL reconstruction. Patients with LARS artificial ligaments recovered earlier than those with autogenous hamstring tendons,and the former had less surgical injury and better postoperative knee stability.
