Radiologic maturation and tunnel changes after all-inside versus standard hamstring ACL reconstruction: a prospective comparative study

AI-ST4 and DSTG ACL reconstruction demonstrated similar graft maturation at 12 months, with less tibial tunnel widening after AI-ST4. At 24 months, clinical outcomes were equivalent between groups; although SNQ and tibial tunnel CSA demonstrated good reproducibility, these imaging differences were not demonstrably associated with functional superiority.
