【摘要】 目的探讨韧带增强重建系统(LARS)人工韧带重建前交叉韧带(ACL)手术的临床效果。方法采用随机数字表法将我院2011年9月至2013年5月收治的60例ACL损伤患者分为LARS组和自体腘肌腱(ST/G组)组,各30例,比较2组患者治疗前与治疗后3、6、9、18个月的Lysholm评分、主客观IKDC评分、末次随访的临床疗效及骨隧道扩大情况的差异。结果LARS组扶拐下地时间、弃拐行走时间、恢复运动时间3项指标均显著短于ST/G组(P<0.05)。与术前相比,2组Lysholm评分及IKDC评分术后3、6、9、18个月均显著好转(P<0.05);术前2组Lysholm评分及IKDC评分比较差异不显著(P>0.05);术后3、6、9个月LARS组Lysholm评分及IKDC评分显著优于ST/G组,至术后18个月2组患者的Lysholm评分及IKDC评分差异不显著(P>0.05)。末次随访时,LARS组疗效分布显著优于ST/G组(P<0.05);LARS组优良率93.33%高于ST/G组的76.67%,但差异不显著(P>0.05)。LARS组共6例患者出现骨隧道扩大,ST/G组14例患者出现骨隧道扩大,ST/G组出现骨隧道扩大率显著高于LARS组(P<0.05)。结论韧带增强重建系统人工韧带重建前交叉韧带较自体腘肌腱重建能够显著加快患者的恢复,同时提高术后疗效及降低术后骨隧道扩大的发生率。更多还原

【Abstract】 Objective To explore the clinical effect of ligament advanced reinforcement system( LARS) artificial ligament reconstruction 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,18 th 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( P < 0. 05). The Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups after treatment were better than those before treatment( P < 0. 05). The difference of Lysholm score and IKDC score between two groups before operation was not significant( P > 0. 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 18 th months after operation,the difference of Lysholm score and IKDC score between 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( P < 0. 05). The excellent and good rate of LARS group( 93. 33%) was higher than that in ST / G group( 76. 67%),but the difference was not significant( P > 0. 05). There were 6 cases of patients with bone tunnel enlargement in LARS group,14 patients had bone tunnel enlargement 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 reconstruction can significantly speed up the recovery of the patients,and improve the postoperative curative effect and reduce the incidence of postoperative bone tunnel enlargement.更多还原
