Anatomic risk factors for ACL injury and post\u2010reconstruction graft failure include a narrow intercondylar notch, low native ACL volume, and increased posterior slope. Regarding anatomic footprints, the femoral attachment is 43% of the proximal\u2010to\u2010distal lateral femoral condylar length whereas the posterior border of the tendon is 2.5\u00a0mm from the articular margin. The tibial attachment of the ACL is two\u2010fifths of the medial\u2010to\u2010lateral interspinous distance and 15\u00a0mm anterior to the posterior cruciate ligament. Anatomic research using radiology and computed tomography to evaluate ACL graft placement shows poor interobserver and intraobserver reliability.<\/jats:p>\n                  <\/jats:sec>\n
