Comminuted tibial end bony avulsion of posterior cruciate ligament (PCL) is a challenging problem in terms of accurate reduction, fixation and union to provide a stable knee. Arthroscopic reduction or a screw fixation is good option for a large fragment but comminuted fragment reduction remains a challenge. Suture bridge technique using two anchors can provide an accurate reduction and stable fixation.
10 patients of isolated comminuted PCL avulsion with a mean age of 30 years were fixed by standard posterior approach using suture bridge technique.
Mean follow up was 12 months. All patients showed radiological union at 12 weeks with a mean Lysholm score of 92. Seven out of ten achieved IKDC grade A and remaining three had grade B. No complication of the procedure were noted.
Suture bridge technique is an excellent option to fix a comminuted PCL avulsion fracture where arthroscopic reduction or open single screw fixation is not a viable due option due to comminution.
后交叉韧带（PCL）胫骨端粉碎性骨撕脱在实现精确复位、固定和愈合以提供稳定膝关节方面是一个具有挑战性的问题。对于大的骨块，关节镜下复位或螺钉固定是不错的选择，但粉碎性骨块的复位仍然是一个挑战。使用两个锚钉的缝线桥技术可以实现精确复位和稳定固定。
10例孤立性PCL粉碎性撕脱患者，平均年龄30岁，采用标准后路入路，使用缝线桥技术进行固定。
平均随访12个月。所有患者在12周时均显示影像学愈合，平均Lysholm评分为92分。10例中有7例达到IKDC A级，其余3例为B级。未观察到该手术的并发症。
对于因粉碎而无法进行关节镜复位或开放单螺钉固定的PCL粉碎性撕脱骨折，缝线桥技术是一种很好的固定选择。
