Association Between Posterior Tibial Slope and Graft Survival in High-Risk Anterior Cruciate Ligament Reconstruction With Lateral Extra-articular Tenodesis

Listen to this summary

This study investigates how posterior tibial slope (PTS) influences graft survival in high-risk anterior cruciate ligament (ACL) reconstruction patients who also underwent lateral extra-articular tenodesis (LET). The authors found that PTS independently predicts graft failure, with a stronger effect in high-risk patients, and identified specific PTS ranges that correlate with lower failure probabilities. Ultimately, while LET offers some protection, higher PTS values are associated with increased rerupture risks, suggesting that steeper slopes may diminish the benefits of the adjunctive procedure.
