膝关节镜下自体腘绳肌腱单束等长重建前交叉韧带疗效分析

Curative effects analysis of arthroscopic single-bundle anterior cruciate ligament reconstruction with autologous hamstring tendon

目的：探讨关节镜下应用自体腘绳肌腱单束等长重建前交叉韧带的手术方法和疗效,提高前交叉韧带断裂患者的临床疗效。方法：膝关节前交叉韧带损伤患者22例,取自体半腱肌腱及股薄肌腱,在关节镜下使用Endobuttom钢板及可吸收挤压螺钉重建固定前交叉韧带和随访观察。结果：22例均获得随访6~18个月。膝关节功能良好,lysholm评分：术前（48.03±4.80）分,术后（91.23±4.05）分,术后评分明显高于术前（P〈0.05）。结论：关节镜下应用自体腘绳肌腱单束等长重建前交叉韧带,微创、并发症少、疗效好,值得临床推广。

Objective： To explore the operative method and clinical effects of arthroscopic single-bundle anterior cruciate ligament（ACL） reconstruction using autologous hamstring tendon,and to improve the clinical efficacy. Methods： 22 patients with ACL injury underwent treatment in our department by ligament reconstruction with autologous semitendinosus-gracilis. Arthroscopic fixation was performed with endobuttom steel plate and absorbable crushing screw. Results： 22 cases were all followed up for 6~18 months. The total patients＇ joint function obtained better recovery. Lysholm score before and after the operations were（48.03±4.80） and（91.23±4.05）, which was statistically different（P0.05）. Conclusion： Arthroscopic single-bundle ACL reconstruction with autologous hamstring tendon can lead to less invasion,fewer complications and better curative efficacy. It is worthy of wider clinical application.
