Single-Bundle Autografts Outperform Single-Bundle Achilles Allograft in Posterior Cruciate Ligament Reconstruction in Terms of Posterior Tibial Translation and Clinical Outcomes, but No Differences Exist Between Double-Bundle Grafts: A Network Meta-analysis

SB autografts outperformed SB Achilles allograft in terms of PTT, and SB BTB had the lowest failure rates, while SB HST had the highest Lysholm scores. DB PCLR demonstrated superior biomechanical outcomes compared with SB reconstruction, regardless of the type of grafts used. All graft groups demonstrated a clinically significant improvement, exceeding the previously established minimal clinically important difference in the Lysholm and Tegner scores.
