Abstract

Posterior cruciate ligament avulsion fractures of the tibia account for approximately 20% of knee ligament injuries. Currently, arthroscopic suture anchor bridge repair has been widely adopted because of its excellent biomechanical properties and long-term prognosis. However, traditional techniques require the anchor to be placed at a nearly vertical angle into the posterior tibial bone bed, presenting technical challenges such as limited vision and narrow operating space, which can lead to issues like anchor displacement or insufficient depth. To address these problems, this study introduces a reverse anchor repair technique, which not only simplifies the surgical steps and shortens the learning curve but also effectively avoids iatrogenic damage to adjacent vascular and neural structures.
