The posterior cruciate ligament (PCL) plays a crucial role for the posterior stability of the knee joint, accounting for 3% to 38% of acute knee injuries and frequently co-occurring with other ligament injuries. PCL tibial avulsion fractures are not rare in clinical practice. Arthroscopic treatment for PCL tibial avulsion fractures has gained acceptance due to its ability to achieve anatomic reduction, restore ligament tension, and improve joint stability while minimizing surgical trauma and facilitating rapid recovery. However, the choice of fixation method remains a topic of ongoing debate. We employed a "Y"-shaped suture technique combined with suspension fixation in the arthroscopic treatment of PCL tibial avulsion fractures. This technique effectively stabilizes the fracture while restoring PCL tension, resulting in improved recovery of knee stability and function.
后交叉韧带（PCL）对膝关节的后稳定性起着关键作用，占急性膝关节损伤的3%至38%，且常与其他韧带损伤同时发生。PCL胫骨撕脱骨折在临床实践中并不罕见。由于关节镜治疗PCL胫骨撕脱骨折能够实现解剖复位、恢复韧带张力、提高关节稳定性，同时将手术创伤降至最低并促进快速恢复，因此已被广泛接受。然而，固定方法的选择仍然是一个持续争论的话题。我们采用“Y”形缝合技术结合悬吊固定来关节镜治疗PCL胫骨撕脱骨折。该技术在恢复PCL张力的同时有效地稳定了骨折，从而改善了膝关节稳定性和功能的恢复。
