摘要
背景:目前同种异体组织移植成为韧带移植重建的一种选择,同种异体骨-髌腱-骨可作为外侧副韧带重建的一种选择。目的:观察采用同种异体骨-髌腱-骨移植重建陈旧性外侧副韧带损伤的临床效果。方法:选择2008-04/2009-12解放军第101医院骨科收治的Ⅲ度陈旧性外侧副韧带损伤患者11例,均采用同种异体髌腱解剖移植重建外侧副韧带。结果与结论:11例患者均获得随访,随访时间12～15个月。切口均Ⅰ期愈合,关节活动范围移植重建后较移植前显著增大(P<0.05)。Lysholm评分末次随访时较移植前显著增加(P<0.05)。移植前内翻应力位X射线平片显示患膝外侧关节间隙较对侧平均增加8～20(12.9±3.5)mm,移植后6个月为-2～3(1.0±1.9)mm,与移植前相比差异有显著性意义(P<0.05),与健侧相比差异无显著性意义(P>0.05)。提示应用同种异体骨-髌腱-骨对陈旧性外侧副韧带损伤进行重建,能够有效恢复膝关节内翻稳定性,对其他软组织重建提供保护作用。
BACKGROUND： AIIogeneic tissue transplantation has become a choice of ligament graft and reconstruction, and allogenic bone-patellar tendon-bone graft is a method for lateral collateral ligament reconstruction. OBJECTIVE： To investigate the clinical effect of allogenic bone-patellar tendon-bone graft for chronic lateral collatera ligament injury. METHODS： From April 2008 to December 2009, 11 cases of Ⅲ degree chronic lateral collateral ligament injury were selected and treated with lateral collateral ligament reconstruction by allogenic bone-patellar tendon-bone graft.RESULTS AND CONCLUSION： All patients were followed-up for 12 15 months. The wound healed by first intention. The movement ranges of the knee were significantly increased preoperatively （P 〈 0.05）. The Lysholm scroe at the last follow-up was significantly increased as compared with preoperatively. Preoperative varus stress radiographs demonstrated the knee lateral joint space increase of 8 to 20 （12.9±3.5） mm in average compared with the contralateral, the knee lateral joint space was 2-3 （1.0±1.9） mm at 6 months postoperatively, and there was a significant difference （P 〈 0.05）, and there was no significant difference when compared with the healthy side （P 〉 0.05）. Reconstruction of the lateral collateral ligament with allogenic bone-patellar tendon-bone graft is a viable option to treat chronic lateral collateral ligament tears, and can restore normal varus stability, and plays a protect effect on other soft tissue repair.
