Background: Anteromedial tibial plateau fracture with posterolateral corner (PLC) injury is a relatively rare combined injury in the clinic. In addition, there is no unified treatment scheme for this combined injury. The purpose of this study was to evaluate the clinical and imaging results of single-stage arthroscopic-assisted surgery for anteromedial tibial plateau fracture with PLC injury, and to explore the advantages of this surgical technique.Method: In this retrospective study, a total of 9 patients (7 males and 2 females) were included, aged 24-64 years (average 40.7 years), treated in our Department of Orthopedics from January 2016 to January 2021. In the preoperative evaluations, there were 9 cases of anteromedial tibial plateau fractures with PLC injuries, 6 cases of concomitant PCL injuries, 6 cases of concomitant medial or lateral meniscus injuries, and 2 cases of concomitant fibular head avulsion fractures. All patients underwent single-stage arthroscopic-assisted surgery.Results: All patients were followed up, and the average follow-up period was 15.2 months (range 12-18 months). The average operation time was 135.6 min (range 100-160 min), and the average surgical blood loss was 87.2 ml (range 60-110 ml). The anatomical reduction was achieved in 9 cases, and the anatomical reduction rate was 100%. The average fracture healing time was 13.1 weeks (range 12-16 weeks). At the last follow-up, the average VAS score was 1 (range 0-2); the average Lysholm function score was 90.7 (range 86-95), and the average IKDC score was 91.4 (range 88-95); the average knee extension angle of all patients was 0° and the average knee flexion angle was 128.3° (average 120-135°); The posterior drawer test, the Lachman test and the dial test were negative for all cases. None of the patients had operation-related complications.Conclusion: Single-stage arthroscopy-assisted surgery in the treatment of anteromedial tibial plateau fracture with PLC injury can achieve good clinical outcomes, restore the stability of the knee joint, and reduce the risk of severe lower extremity dysfunction.
