Fig. 2From: Effects of modified trans-tibial versus trans-portal technique on stress patterns around the femoral tunnel in anatomical single-bundle ACL reconstruction with different knee flexion angles using finite element analysisA sequential flexion of ACL reconstructed knee model was reproduced at four different angles (0°, 45°, 90° and 135°) as the femur was moved to each flexed position according to a 3D coordinate system based on the fixed tibia. Meanwhile, the stress concentration and its maximum value were monitored in the lateral femoral condyle around the femoral tunnelBack to article page
