We think this has broad domain relevance to 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.
