【摘要】 目的  探讨关节镜辅助下经腘窝小切口应用锚钉固定治疗后交叉韧带胫骨止点粉碎骨折的临床效果。 方法  2007年2月-2008年12月对22例急性后交叉韧带胫骨止点骨折患者，采用关节镜辅助下经腘窝小切口切开复位，利用缝合锚钉重建止点，固定治疗后测试交叉韧带的张力和稳定，采用Lysholm膝关节功能评分评定膝关节功能。 结果  骨折平均愈合时间为6周，平均屈膝活动度（120±3）°。Lysholm膝关节功能评分为（92±2）分。 结论  关节镜辅助经腘窝小切口锚钉固定治疗后交叉韧带胫骨止点粉碎骨折，可协助诊断关节内韧带及骨折损伤情况，对韧带止点进行重建，操作简便，早期功能锻炼有助于关节功能恢复。
【Abstract】 Objective  To explore surgical technique and the results of arthroscopic reduction and fixation for the treatment of comminuted fracture of the posterior cruciate ligament (PCL) from the tibia using suture anchor through an posterolateral portal via popliteal fossa. Methods  Twenty-two patients who were operated through an posterolateral portal via popliteal fossa, the fragment was fixed by using suture anchor to reestablish the insertion, test the tension and stabilization of PCL. Lysholm score was used to evaluate the knee function. Results  The bone union was confirmed by X-ray films at the 6 weeks postoperatively. The ROM of knee joint relaxation was 120±3°. The Lysholm score was 92±2. Conclusion  The displaced fragment of the comminuted fracture of the posterior cruciate ligament from the tibia can be reduced and fixed with the suture anchor arthroscopicly. Using suture anchors demonstrate a reliable and easy to use technique. Operation under arthroscopy helps diagnose and treat other complications inside knee joint. In addition, early functional exercise contributes torapid recovery of knee joint’s function.
