a-c Glenohumeral (GH) AUC in the coronal plane (x-axis), sagittal plane (y-axis), and transverse (z-axis) planes, respectively. Four study groups: baseline, rotator interval 2 cm insult (OPEN), side-by-side repair (Side-to-Side) and tightened rotator interval repair (Overlap) are identified by dark blue, cyan, yellow and red lines, respectively. Symbol (*) denotes data significance (p ≤ 0.005) following insult (Open) of the rotator interval compared to Baseline. Symbol (◊) denotes data significance (p ≤ 0.005) following both mechanisms of repair (Side-to-Side, Overlap) compared to Baseline. Symbol (§) denotes data significance (p ≤ 0.005) between side-by-side repair (Side-to-Side) and tightened rotator interval repair (Overlap) and insult (Open) of the rotator interval when compared to Baseline
