title: A comparison of distal femoral physeal defect and fixation position between two different drilling techniques for transphyseal anterior cruciate ligament reconstruction.
abstract: The defect of the femoral tunnel at the level of the physeal scar during transtibial and anteromedial portal (AMP) drilling for transphyseal anterior cruciate ligament reconstruction was compared. Five matched pairs of knees (n=10) were drilled, and computed tomography was used to evaluate tunnel position and size at the level of the physeal scar. Significant radiographic changes were observed, including tunnel defect area at the physeal scar: 0.44 cm (1.2%) in the transtibial group versus 0.99 cm (2.7%) in the AMP group (P=0.008). AMP drilling creates a larger and more lateral tunnel defect at the level of the physeal scar.
