Figure 5.

Receiver operating characteristic curve for all reviewers based on the minimum magnetic resonance imaging cross-sectional area (CSA) of the average semitendinosus CSA + gracilis CSA (STGR) to achieve an 8-mm autograft. This curve displays the ability of the average STGR to discriminate values above and below the 8-mm cutoff point. A blue line is drawn at 45° tangent to the curve to display the point that maximizes sensitivity and specificity.¹⁰ The point at which this line intersects with the curve corresponds to a CSA of approximately 21.1 mm².
