Clinical Efficacy of Open Reduction and Suture Bridge Fixation for PCL Tibial Avulsion Fractures

Under general anesthesia, patients were positioned prone, and a midline posterior incision was made at the level of the popliteal fossa. After incising the fascia, careful dissection was undertaken to expose the posterior joint capsule and fracture fragment, with particular attention to safeguarding the neurovascular structures. Once the fracture site was fully exposed, hematoma and any interposing soft tissue were meticulously cleared to prepare for reduction. The avulsed bone fragment, located at the PCL insertion site, was identified and prepared for fixation. A suture anchor (Johnson \& Johnson, USA) was carefully implanted into the prepared osseous bed. The suture threads were passed anteriorly around the PCL and configured in a figure-of-eight pattern to achieve precise anatomical reduction of the fracture fragment. To enhance fixation stability, two extracortical anchors (Johnson \& Johnson, USA) were additionally positioned approximately 2 cm distal to the fracture site, securing
