Association Between Posterior Tibial Slope and Graft Survival in High-Risk Anterior Cruciate Ligament Reconstruction With Lateral Extra-articular Tenodesis
The study aims to investigate the relationship between posterior tibial slope (PTS) and graft survival in anterior cruciate ligament (ACL) reconstruction with lateral extra-articular tenodesis (LET).
Analyzed graft outcomes in high-risk ACL reconstruction patients with varying levels of posterior tibial slope.
Compared graft failure rates between groups with and without lateral extra-articular tenodesis.
Evaluated the direct correlation between PTS values and rerupture rates.
Found that higher posterior tibial slope is linked to increased graft failure rates in both treatment groups.
Demonstrated that moderate PTS values correlate with lower failure risks when lateral extra-articular tenodesis is applied.
Revealed steeper slopes amplify the risk of reruptures, reducing LET's protective effect.
