Femoral tunnel position in anatomical double-bundle ACL reconstruction is not affected by Blumensaat's line morphology.

AM and PL femoral tunnel position in anatomical double-bundle ACL reconstruction was not affected by the morphological variations of the Blumensaat's line. Surgeons do not need to consider Blumensaat's line morphology if AM and PL femoral tunnel position is targeted at the bottommost point of the lateral condyle. Level of evidence Ⅳ. Keywords ACL; double-bundle ACL reconstruction; Blumensaat's line; femoral tunnel position.
