Anatomic, Transepiphyseal Anterior Cruciate Ligament Reconstruction.

Abstract

Our technique for physeal-sparing, anatomic anterior cruciate ligament (ACL) reconstruction reliably produces femoral tunnels that are of adequate length and that safely avoid the femoral physis without the addition of time-consuming surgical methods or substantial utilization of fluoroscopy. Obtain radiographs and MRI of the knee as well as an anteroposterior radiograph of the hand (to obtain a bone age). The affected knee must be able to flex at least 90° with the end of the operative table lowered, in order to properly visualize the anatomy of the ACL femoral footprint. Maintain soft-tissue remnants at both the femoral and the tibial footprint in order to individualize the anatomy. Visualize and palpate your previously marked popliteal sulcus and lateral epicondyle; these landmarks are the crucial extra-articular points for establishing a safe femoral tunnel. The tibial tunnel can be safely drilled in a transphyseal manner in skeletally immature patients. Use the Arthrex ACL TightRope RT for femoral fixation. As a skeletally immature athlete differs from a more mature athlete in several important ways, alter the postoperative protocol accordingly. Our clinical experience has corresponded to our MRI-based findings from our original study¹⁴, and we have not observed any physeal or chondral injuries leading to growth disturbances from our femoral tunnels.
