Biomechanical Effects of Aspect Ratio of the Knee during Outside-In Anterior Cruciate Ligament Reconstruction Surgery

Figure 2

The process of computational analysis on ACLR for the 3D knee model showing recommended tunnel entry points during continuous motions; Step 1: the starting point for the three investigated femoral tunnels was the 45° posterior-proximal angle at 5 mm (A), 10 mm (B), and 15 mm (C) distances from the lateral epicondyle. Step 2: follow the shape of the knee using motion analysis data. Step 3: calculate stresses of the implant.
