关节镜下采用腘绳肌肌腱指骨钢板悬吊固定重建前交叉韧带

Arthroscopic reconstruction of anterior cruciate ligament with hamstring tendons and mini-plates

[目的]探讨关节镜下采用腘绳肌肌腱指骨钢板悬吊固定法重建前交叉韧带（ACL）的临床效果。[方法]对13例前交叉韧带断裂的患者，在关节镜下采用6～8股腘绳肌肌腱进行单束双隧道重建，4孔指骨钢板对移植物行悬吊式固定。术后1a随访，并按照Lysholm膝关节评分标准评价疗效。[结果]12例患者（92．31％）Lachman试验阴性，1例患者Lachman试验阳性，12例患者轴移试验阴性，1例患者阳性。按照Lysholm膝关节评分标准，评分从47．77±1．96提高至95．38±4．74，差异有显著性意义（P〈0．01）。[结论]关节镜下采用腘绳肌肌腱指骨钢板悬吊固定重建前交叉韧带是恢复膝关节稳定性的可靠方法。

[ Objective ] To study the effect of arthroscopic reconstruction of anterior cruciate ligament with hamstring tendons and mini-plates. [ Method ] Thirteen cases of anterior cruciate ligament ruptures were reconstructed arthroscopically with over six strands of hamstring tendons in way of one-bundle and two-tunnel reconstruction. The grafts were fixed with suspension technique by mini- plates. The patients were followed up for one year. The clinical results were evaluated according to Lysholm rating scale. [Result]Twelve patients （92.31%） had negative Lachman test, and one patient showed positive Lachman test. Pivot shift test was negative in 12 cases, and was positive in one case. The Lysholm score increases from 47.77 ± 1.96 to 95.38 ±4. 74 （ P 〈0.01 ）. [ Conclusion] Arthroscopic reconstruction of anterior cruciate ligament with hamstring tendons and mini-plates is reliable to restore the stability of the knee.
