Figure 5:

Magnetic resonance imaging from 7 of the 10 patients in the autograft ACL reconstruction group in the first-in-human study (sagittal view, 24 months after ACL reconstruction). All subjects had intact grafts coursing from the femoral to tibial tunnels (arrows). The intact fibers have low signal intensity (black) reflecting highly organized tissue with little free water. (Used from Murray et al, OJSM, 2019⁴⁹), with some variability among patients in the amount of highly organized tissue and less organized tissue in the region of the graft.
