Outcomes of ACL Reconstruction with Quadriceps Tendon Graft Based on Graft Diameter Relative to Notch Width
Listen to this summary
This study investigates how the diameter of quadriceps tendon (QT) autografts and the ratio of graft diameter to femoral notch width (D-N ratio) impact clinical outcomes, specifically rates of symptomatic knee stiffness and revision ACL reconstruction (ACLR). The authors found that a D-N ratio greater than 0.55 and lateral meniscal repair were associated with higher rates of subsequent surgery for knee stiffness, while graft diameter and D-N ratio did not significantly influence the likelihood of revision ACLR. The findings suggest that avoiding overstuffing the femoral notch may help reduce the risk of knee stiffness without increasing revision rates.
