Evaluation on function of knee reconstruction with LARS artificial ligament of the ACL / 局解手术学杂志

ABSTRACT

Objective To explore the clinical effect of ligament advanced reinforcement system ( LARS) artificial ligament reconstruc-tion of the anterior cruciate ligament ( ACL) in the operation. Methods Sixty patients with ACL injury in our hospital from September 2011 to May 2013 were randomly divided into LARS group and autologous hamstring tendon ( group ST/G) group with 30 cases in each group,the Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups before treatment and at 3rd,6th,9th, 18th months after treatment were compared. Results The time of walking with crutch,ambulation and restore movement in LARS group were obviously shorter than those in ST/G group(P0. 05). The Lysholm score and IKDC score of LARS group at 3rd,6th,9th months after operation was higher than that of ST/G group,and at 18th months after operation,the difference of Lysholm score and IKDC score be-tween two groups was not significant (P>0. 05). At the last follow-up,the distribution effect of LARS group was higher than that of ST/G group (P0. 05). There were 6 cases of patients with bone tunnel enlargement in LARS group,14 patients had bone tunnel en-largement in ST/G group. The bone tunnel enlargement rate was significantly higher than that of the LARS group (P<0. 05). Conclusion Ligament advanced reinforcement system of artificial ligament in anterior cruciate ligament reconstruction with autologous hamstring tendon re-construction can significantly speed up the recovery of the patients,and improve the postoperative curative effect and reduce the incidence of postoperative bone tunnel enlargement.
