"the angle measured between a line drawn along the femur diaphysis and the femoral tunnel angle must be ~39°; angles of approximately ≤17° are associated with rotational instability 1."
"when the femoral tunnel is drilled through the tibial tunnel, it is recommended to drill the tibial tunnel at an angle of 65° to 70° in the coronal plane, tibial tunnel angle of ≥72° is associated with greater loss of flexion and anterior laxity 2."
"migrated/displaced interference screw from the tibial or femoral canal 3."
"the angle measured between a line drawn along the femur diaphysis and the femoral tunnel angle must be ~39°; angles of approximately ≤17° are associated with rotational instability 1."
"anterior wall of tibial tunnel should be entirely posterior to and parallel to the line drawn along the roof of the intercondylar notch (Blumensaat line); if the tibial component is too anterior, graft impingement or graft failure will happen, and if it is too posterior (vertical graft) the patient will suffer from a translational laxity"
