Summary

Abstract Background: Posterior cruciate ligament (PCL) tibial avulsion fractures significantly impair knee function; however, optimal surgical fixation approaches are not agreed upon. The investigators performed this study to compare the clinical outcomes of PCL tibial avulsion fractures treated with open reduction and anchor suture bridge fixation.

Methods: A total of 17 patients underwent open reduction and anchor suture bridge fixation following injury. The investigators recorded operation time, intraoperative and postoperative complications, and used imaging to assess fracture reduction and healing. Visual Analog Scale (VAS), Lysholm Knee Scoring Scale, International Knee Documentation Committee (IKDC) score, and knee range of motion (ROM) were evaluated preoperatively, 3 months postoperatively, and at final follow-up.

PROCEDURE

Clinical Efficacy of Open Reduction and Anchor Suture Bridge Fixation

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
