We think this might be relevant to the clinical guidance for ACL Graft Choice Risk Factors.
ACL Graft Choice Risk Factors
Failure Risk Profile
Unknown
Enter Age
Patient Age
Tegner Activity Target
Evidence Base: Strong evidence shows that allografts (cadaveric tissue) have ~4.5x higher failure rates in patients < 25 compared to autografts.

When to Use
Precision Graft Selection
Pre-operative risk-stratification for primary ACL reconstruction (ACLR) to minimize the 24-month failure window.
Identifying high-risk morphological phenotypes: Younger age (≤18), high-grade preoperative laxity, and posterior tibial slope (PTS) >9.4°.
Evaluating the threshold for Lateral Extra-articular Tenodesis (LET) augmentation—specifically in hamstring autograft cohorts.
Counseling the "e-patient": Addressing the gap between Internet-driven preferences (often favoring allografts for recovery speed) and clinical failure data in young cohorts.
The Clinical "Red Flags" for Graft Failure
The Stability 1 Study identified high-grade preoperative knee laxity (Grade 3 Lachman/Pivot Shift) as the strongest predictor of graft rupture, increasing odds by 3.27x.
