Autologous hamstring graft diameter in ACL reconstruction linked with likelihood for revision

Investigators of this study found a 0.82-times lower chance of patients needing a revision ACL reconstruction for each 0.5-mm increase in graft diameter from 7 mm to 9 mm when hamstring autograft was used for the primary reconstruction.
Using the Kaiser Permanents ACL Reconstruction Registry, researchers performed a case-control study and identified 124 patients who underwent primary ACL reconstruction with a hamstring autograft and then underwent a subsequent revision. They matched these cases to 367 controls who did not need revision.
Findings showed the cases and controls were not significantly different with regard to median age and BMI, distribution of sex, and use of femoral or tibial fixation. Investigators found the mean graft diameter for the revision and control group was 7.9 mm and 8.1 mm, respectively. The chance of a patient needing revision ACL reconstruction was 0.82-times lower with every increase of 0.5 mm in the graft diameter between 7 mm and 9 mm. ‒ by Monica Jaramillo
