PT Inquest 410: Allograft Vs. Autograft ACLR Outcomes
Aug 19, 2025
The hosts dive into the nuances of ACL reconstruction, comparing allograft and autograft methods. They discuss a pivotal study that highlights the benefits of autografts, especially concerning recovery outcomes. The effectiveness of allografts, particularly sterilization methods and the risks of graft rupture, is critically analyzed. A playful debate on graft selection showcases the complexities behind surgical choices paired with personal anecdotes. The importance of understanding biomechanics and patient history in making informed decisions rounds out their engaging conversation.

Episode notes
Allograft Failure Linked To Younger Patients
- The MOON cohort found higher ACL graft rupture risk with allografts and in younger patients.
- The paper cautions using allografts in younger, high-activity individuals due to increased failure rates.
Sterilization And Tensile Strength Are Not Definitive
- Sterilization method (e.g., irradiation) is not consistently linked to allograft failure in modern data.
- Tensile strength ranges overlap between autografts and allografts, making simple biomechanical comparisons misleading.
Missing Rehab And Return-To-Sport Data
- The MOON study did not record rehabilitation details, return-to-sport timing, or activity exposure.
- These missing variables limit conclusions about why re-ruptures happened and when.
