X-ray, magnetic resonance imaging (MRI), and computed tomography (CT) scans in case 1 (a–e). (a) Anteroposterior view of the X-ray. (b) Lateral view of the X-ray. (c) T1-weighted MRI image of the sagittal plane, showing residual reconstructed anterior cruciate ligament. (d) Three-dimensional (3D) CT image of the femoral tunnel position of the left knee. The yellow dot circle shows the aperture of the femoral tunnel. CT shows nonanatomical tunnel position (anterior and distal). (e) 3D CT image of the tibial tunnel position
