1、临床医学论文-膝矢节后内侧结构损伤早期修复疗效观察作者:刘宪民,刘松波,张志富,周大鹏,韩文锋张敬东,祖启明【摘要】[目的]探讨膝矢节后内侧结构损伤(内侧副韧带MCL,后斜韧带POL)的手术治疗效果。[方法]2002年1月〜2007年10月共治疗14例后内侧结构损伤中12例合并ACL断裂,2例合并PCL断裂。后内侧结构损伤分型:I型:8例,后内侧结构于股骨止点撕裂,带小片骨块,0.8〜1.0cm。U型:2例,后内侧结构于股骨止点撕裂,无骨块。皿型:2例,后内侧结构于体部断裂。IV型2例,后内侧结构于胫骨止点撕裂。后内侧结构损伤修复:8例采用星状钢板螺钉,4例采用GII锚钉(2例固定于股骨内上髒
2、,2例固定于胫骨内侧止点)。尖节镜下交叉韧带重建:8例ACL断裂采用自体半腱肌、股薄肌重建ACL(tranfix)术式,2例ACL断裂采用骨■離腱■骨术式,2例ACL于胫骨止点撕脱矢节镜下复位空心钉固定,2例PCL断裂采用一端带骨块异体跟腱重建PCL。[结果]本组14例中2例随访4个月后失访平均随访12个月(6〜18个月)交叉韧带损伤重建后评分(Lysholm)74〜94分(平均81・2分),术前50〜60分(平均56・7分)。后内侧结构修复后10例膝伸屈范围正常,2例伸直受限5°。外翻应力试验于0°位,9例正常,2例+,1例卄。[结论]膝后内侧结构损伤积极外科治疗可以收到较好的手术效果,恢复
