Effect of femoral tunnel positions on graft stress in outside‐in ACL reconstruction surgery during continuous knee motion: A simulation study

Kang, Kyungmin, Bae, Tae Soo·2017·The International Journal of Medical Robotics and Computer Assisted Surgery

Abstract

Background: Previous studies regarding the optimal femoral tunnel location for an anterior cruciate ligament (ACL) reconstruction were based on static experiments at specific angles, and did not consider continuous motion of the knee. Methods: Twenty‐four surgical sites were set and continuous kinematic data, obtained from motion analysis, was used to describe knee movement. The bending angle and stress of the ACL graft as well as the length of the femoral tunnel was calculated through multi‐flexible body dynamics analysis. Results: The lowest stress was found at both 5 mm and 10 mm radius at a proximal posterior of 45°, and the highest stress was also found at a distal 15 mm radius. Relatively high stresses were also identified between the distal and anterior regions as well as the distal and posterior regions at 15 mm radius. Conclusion: Considering the availability of surgery, it was identified that the optimum femoral tunnel location is at 10 mm radius locations at a proximal posterior of 45°.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
