关节镜下FasT-Fix系统修复半月板中期疗效观察

Mid-term Outcomes of Meniscal Repair with FasT-Fix System

目的探讨关节镜下FasT-Fix系统进行半月板修复的临床效果。方法 2005年4月～2007年7月,32例(34侧)半月板损伤应用Fast-Fix系统(美国Smith&Nephew公司)进行了关节镜下全内镜下的半月板缝合,合并前交叉韧带断裂者同时用自体半腱、股薄肌腱进行前交叉韧带的单束或双束重建手术。评价半月板缝合后的临床愈合情况,并进行IKDC评分、Lysholm评分、Tegner评分。结果随访26～52个月(平均35个月),按照Barrett标准评价,30侧临床愈合,临床愈合率为88.2%(30/34)。IKDC评分由术前(45.3±18.7)分提高到术后(78.7±13.6)分(t=7.168,P=0.000),Lysholm评分由术前(43.5±22.2)分提高至术后(84.8±14.7)分(t=8.493,P=0.000),Tegner评分由术前(3.0±2.1)分提高至术后的(6.1±1.9)分(t=6.796,P=0.000)。结论应用Fast-Fix系统进行半月板缝合具有很好的中期疗效。

Objective To evaluate the mid-term efficacy of FasT-Fix system in arthroscopic meniscal repair. MethodsFrom April 2005 to July 2007,FasT-Fix system（Smith Nephew,USA） was used for arthroscopic meniscal repair in 32 patients（34 sides）.Concurrent single or double bundle anterior cruciate ligaments reconstruction was performed with the auto semitendinosus and gracilis tendon.Clinical healing condition and IKDC,Lysholm,and Tegner scores were evaluated after the procedure. Results The patients were followed up for 26 to 52 months with a mean of 35 months.According to Barrett standards,30 sides were healed（88.2%）.IKDC,Lysholm,and Tegner scores were improved significantly after the operation [（45.3±18.7） vs.（78.7±13.6）,t=7.168,P=0.000;（43.5±22.2） vs.（84.8±14.7）,t=8.493,P=0.000;and（3.0±2.1） vs.（6.1±1.9）,t=6.796,P=0.000;respectively].Conclusions Arthroscopic meniscal repair using FasT-Fix system can provide good mid-term results.
