A Comparative Study Of LARS Ligament In The Reconstruction Of Anterior Cruciate Ligament Acute Knee Injury

Objective:The study compared acute and chronic anterior cruciate ligament reconstruction with ligament advanced reinforcement system artificial ligament. Methods:28 patients were enrolled in the study and divided into two groups based on the elapsed time between the injury and reconstruction: the acute group(2–6 weeks) and the chronic group(5–10 months) during the period between March 2006 and November 2008. The outcomes were evaluated using the Lysholm knee scores, the Tegner activity scores, a KT-1000 Arthrometer, and the International Knee Documentation Committee(IKDC) scoring system. Results:The results of Lachman test, anterior drawer test, and pivot shift test were negative. Knee function scores was increased and anterior laxity was decreased in the acute group compared to the chronic group(p <.05). There were no statistically significant differences in Lysholm scores, Tegner activity scores, and the IKDC evaluation between two groups(p>.05). ConclusionsThe earlier ACL reconstruction using a LARS graft may provide an advantage in the treatment and rehabilitation of ACL rupture.
