NASHVILLE, Tenn. — An elevated or "steep" posterior tibial slope, confirmed with imaging, increased the graft re-rupture risk in patients undergoing revision ACL reconstruction, according to an orthopedic sports medicine specialist.

"We know from biomechanical studies that increased tibial slope is associated with increased anterior tibial translation, as well as strain in the ACL," Robert A. Duerr, MD, an orthopedic surgeon at Ohio State University Wexner Medical Center, said in his presentation at the American Orthopaedic Society for Sports Medicine and Arthroscopy Association of North America Combined Meeting. "There have also been clinical studies that have shown elevated tibial slope both in ACL primary injuries, ACL graft failures and in multiple ACL graft failures."
