Abstract:

目的探讨改良 Laprade 法重建后外侧结构以及前外侧韧带治疗膝关节外侧损伤的近期疗效。方法2013 年 6 月—2015 年 7 月,收治 13 例 膝关节多发韧带损伤患者。男 9 例,女 4 例;年龄 23~49 岁,平均 38 岁。交通事故伤 7 例,高处坠落伤 4 例,运动伤 2 例。损伤至手术时间 18~92 d,平 43 d。患者前、后抽屉试验及 Lachman 试验均呈阳性,伴内翻、前后外旋不稳。膝关节 Lysholm 评分为(38.4±7.7)分。国际膝关节文献委员会(IKDC)综合评分均为 D 级。后外侧结构损伤根据Fanelli分型标准,均为C型。术中取健侧自体肌腱,关节镜下重建前、后交叉韧带,并联合后外侧切口行改良 Laprade 法重建后外侧结构及前外侧韧带。结果术后切口均Ⅰ期愈合。患者均获随访,随访时间 12~36 个月,平均 19 个月。末次随访时,患者前、后抽屉试验及 Lachman 试验均呈阴性;2 例内翻不稳,1 例后外旋转不稳。无前外旋转不稳定。膝关节 Lysholm 评分为(88.6±12.7)分,与术前比较差异有统计学意义(t=13.852,P=0.000)。IKDC 综合评分:A 级 8 例,B 级 4 例,C 级 1 例;与术前比较差异有统计学意义(Z=3.182,P=0.000)。结论对于膝关节外侧损伤,应用自体肌腱采用改良 Laprade 法解剖重建后外侧结构及前外侧韧带,可获得较好近期疗效
