关节镜下六股腘绳肌腱带骨膜瓣外翻缝合法重建前交叉韧带

目的探讨6股腘绳肌腱带骨膜瓣外翻缝合法在关节镜下重建前交叉韧带(anterior cruciate ligament,ACL)的可行性。方法 2008年4月-2009年4月,对34例ACL损伤患者于关节镜下采用6股腘绳肌腱带骨膜瓣外翻缝合、双Rigidfi x固定法重建ACL。男30例,女4例;年龄19～54岁,平均29.4岁。致伤原因:运动伤19例,交通事故伤8例,摔伤5例,其他伤2例。左膝19例,右膝15例。病程3周～18个月,中位病程9.4个月。Lachman试验及前抽屉试验均呈阳性。患膝Lysholm评分为(61.5±3.6)分。MRI检查示ACL断裂26例,损伤8例。结果术后患者切口均Ⅰ期愈合,无早期相关并发症发生。28例获随访,随访时间12～32个月,平均16.1个月。术后12个月Lachman试验均呈阴性。患者膝关节伸直均达0°,屈曲120～150°,平均132.5°;膝关节正侧位X线片及MRI检查均未见骨道扩大。末次随访时按照膝关节疗效评定标准,获优25例,良1例,可2例,优良率92.9%。Lysholm评分为(91.0±3.2)分,与术前比较差异有统计学意义(t=32.78,P=0.00)。结论 6股腘绳肌腱能保证足够的抗拉强度,同时使用双Rigidfi x固定法固定可靠,骨膜瓣外翻缝合可促进腱骨愈合,是一种较好的ACL重建方法。

ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION WITH SIX STRANDS OF HAMSTRING TENDONS ENVELOPED BY PERIOSTEUM

Objective To evaluate the feasibility of the anterior cruciate ligament(ACL) reconstruction with 6 strands of hamstring tendons enveloped by periosteum.Methods Between April 2008 and April 2009,34 patients with ACL injury were treated,ACL of whom was reconstructed with 6 strands of hamstring tendons enveloping of periosteum and double Rigidf ix f ixation.There were 30 males and 4 females,aged 19-54 years with an average of 29.4 years.The causes of injury included sport in 19 cases,traffic accident in 8 case...
