This study describes a method of fixing posterior cruciate ligament (PCL) avulsion fractures called the arthroscopic crisscross technique. PCL avulsion fracture is a rare injury that generally occurs in young patients. A displaced avulsion fracture at the tibial attachment of the PCL is an indication for surgical reduction and internal fixation given that nonunion, posterior instability, and early degenerative changes of the knee are common consequences of conservative treatment. This study describes all-arthroscopic fixation of the PCL avulsion injury using 2 No. 2 FiberTape sutures (nonabsorbable polyblend; Arthrex) via the arthroscopic crisscross technique. The No. 2 FiberTapes crisscross each other over the avulsed fragment. Through tensioning of both No. 2 FiberTapes, they are fixed anteriorly using a suture button. This technique can be considered a safe and effective method using minimal resources for the fixation of the avulsed PCL from its tibial footprint.
本研究描述了一种治疗后交叉韧带（PCL）撕脱骨折的固定方法，称为关节镜下十字交叉技术。PCL撕脱骨折是一种罕见的损伤，通常发生在年轻患者中。鉴于保守治疗常见的后果包括骨不连、后向不稳定和膝关节早期退变，PCL在胫骨附着处的移位性撕脱骨折是手术复位和内固定的指征。本研究描述了通过关节镜下十字交叉技术，使用2根2号纤维带缝线（不可吸收聚混物；Arthrex公司）对PCL撕脱损伤进行全关节镜固定。2号纤维带在撕脱的骨块上相互交叉。通过拉紧两根2号纤维带，使用缝线纽扣将它们固定在前侧。该技术可被认为是一种安全有效的方法，利用最少的资源将撕脱的PCL从其胫骨附着点进行固定。
