Biomechanical analysis of ideal knee flexion angle for ACL graft tensioning utilizing multiple femoral and tibial tunnel locations

Video Transcription

Video Summary

The video is a presentation of a biomechanical study on the ideal knee flexion angle for ACL graft tensioning. The study analyzed different femoral and tibial tunnel locations and their impact on graft excursion. The researchers found that the ACL is not isometric, and tunnel location determines the flexion angle for maximum graft excursion. The femoral tunnel placement was found to be statistically significant, while the tibial tunnel was not. The findings suggest that surgeons should adjust graft tension based on the tunnel location to reduce the risk of re-rupture. Proper tunnel placement is crucial for successful ACL reconstructions. No credits were mentioned in the video.
