Biomechanical Analysis of Tibial Motion and ACL Graft Forces after ACLR with and without LET at Varying Tibial Slopes

Video Transcription

Video Summary

The video features a presentation by Dr. Lee and Dr. Mateva discussing the effects of posterior tibial slope on ACL graft forces and potential treatment options. The researchers conducted a study using cadaveric knees and performed ACL reconstruction with a soft tissue graft, examining the effects of adding lateral extra-articular tenodesis (LAT) in relation to posterior tibial slope. They found that an increase in posterior tibial slope led to increased graft forces and anterior tibial translation. Furthermore, they observed that adding LAT reduced graft forces by approximately 8.3% at 30 degrees of flexion, but a bony correction had an even greater impact. Overall, the study highlights the importance of considering both soft tissue and bony procedures in ACL reconstruction to optimize outcomes and minimize risks.
