Subregion SUV. Graph displaying the metabolic activity (y-axis) of the femoral tunnel, intra-articular graft, and tibial tunnel split into proximal, central, and distal subregions (x-axis). An exaggerated sketch of the subregions is overlaid above to correlate with the subregions on the x-axis. The metabolic activity of the subregions is differentiated into the three-month (yellow), six-month (purple), and 12-month (brown) time periods. ^ and ⁺ denote significance (p < 0.05) between the distal and proximal subregions and the six-month and 12-month time-periods, respectively
