Extract

Overview
Introduction

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.

Step 1: Preoperative Planning

Obtain radiographs and MRI of the knee as well as an anteroposterior radiograph of the hand (to obtain a bone age).

Step 2: Patient Setup, Portal Placement, and Graft Harvest

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.

Step 3: Prepare ACL Footprint and Establish Far Anteromedial Portal

Maintain soft-tissue remnants at both the femoral and the tibial footprint in order to individualize the anatomy.

Step 4: Identify Extra-Articular Landmarks and Prepare Femoral Tunnel

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.

Step 5: Prepare Tibial Tunnel

The tibial tunnel can be safely drilled in a transphyseal manner in skeletally immature patients.

Step 6: Fix Graft

Use the Arthrex ACL TightRope RT for femoral fixation.

Step 7: Postoperative Care

As a skeletally immature athlete differs from a more mature athlete in several important ways, alter the postoperative protocol accordingly.

Results

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.
