Increased Posterior Tibial Slope is Associated with Revision Anterior Cruciate Ligament Reconstruction Graft Re-Rupture

Video Transcription

Video Summary

This study investigates the link between elevated posterior tibial slope (PTS) and revision ACL graft failure. Researchers compared PTS measurements on knee X-rays and MRI in patients with ACL revision failures versus matched controls. Findings showed that a medial tibial slope greater than 14 degrees increased the odds of graft failure by 18.7 times. Elevated PTS was significantly associated with higher failure rates, highlighting its role as a modifiable risk factor. Limitations included retrospective design and measurement variability. The study suggests considering slope-reducing osteotomies in revisions and calls for prospective research to optimize treatment strategies.
