Revision ACL reconstruction outcomes are worse than primary, and graft choice is thought to affect rerupture. Many surgeons assume the prior surgery dictates what graft they can use at revision. Using the 1200-patient MARS cohort and propensity score analysis, this study asked what actually drives autograft versus allograft selection in the revision setting.
The clinical logic runs in two steps. Earlier MARS work showed autograft cuts revision rerupture 2.78 times, so graft choice affects outcome. This paper then shows the surgeon, not the patient's prior surgery, is the dominant driver of that choice, about 5 times stronger than any other factor.
The practical message: if you believe autograft is better at revision, you have the ability to choose it. Don't assume the index surgery locks you in. When you counsel a revision patient, know your own bias, because two surgeons facing the identical case may choose oppositely (28.6x autograft vs 31.9x allograft).
Predictable pushes toward allograft include a prior autograft, older age, a second revision, and concurrent MCL/PM repair. Recognize these so the decision is deliberate rather than reflexive.
