Fig. 4From: Influence of femoral tunnel exit on the 3D graft bending angle in anterior cruciate ligament reconstructionSchematic illustration of different flexion grades and measurement of graft bending angle (GBA). GBA: Graft bending angle. The tibia moved around the femur for 0, 30, 60, 90, 120° of flexion (A). 3D GBA between ACL (pink) and femoral tunnel (violet) illustrated from an anterior and lateral view (B)Back to article page
