Arthroscopic Anterior Cruciate Ligament Tibial Eminence Avulsion Fracture Repair With Reversed Suture Anchor.

Abstract

Anterior cruciate ligament tibial eminence avulsion fracture may result in knee instability if not properly treated. Arthroscopic treatment has shown favorable clinical outcomes. Currently, high-strength suture fixation through the tibial tunnel and anchor suture-bridge technique are widely used surgical techniques. Although the suture-bridge technique exhibits superior biomechanical properties compared with high-strength suture fixation, it presents challenges in anchor placement and risks anchor dislodgement from cancellous bone, potentially resulting in fixation failure. To address these limitations, we employ a reversed anchor repair technique for tibial eminence avulsion fracture. This method achieves anatomical reduction of fracture fragments, enhances fixation strength, and ensures favorable biomechanical outcomes.
