TT\u2010PCL was measured using 3 distal\u2010proximal placements of the dorsal condylar line (proximal, middle, and distal), and values were compared between the instability and control groups and across measurement locations.

Receiver operating characteristic analysis showed moderate discrimination (area under the curve 0.67 proximal, 0.67 middle, and 0.69 distal).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>TT\u2010PCL measurements increase as the dorsal tibial condylar line is selected more distally, underscoring the need for consistent reference point selection. Normalizing to tibial width reduces variability and enhances comparability across patients.
