Tibial eminence fractures most commonly occur in young children and adolescents with open physes. Displaced fractures are typically treated with surgical reduction and fixation. Multiple arthroscopic techniques and fixation constructs have been described. However, many of these techniques violate the physis with a risk of growth disturbance and deformity from asymmetrical physeal growth. This technical note details a surgical technique of arthroscopically assisted suture fixation of a comminuted tibial spine fracture using all-epiphyseal bone tunnels and knotless anchors. In this construct, sutures passing through the substance of the anterior cruciate ligament help to eliminate residual laxity, all-epiphyseal bone tunnels avoid growth disturbance, and suture anchors reduce persistently displaced anterior comminution.
