PCL injuries have been emphasized in previous literature to be frequently associated with posterolateral rotatory instability. However, diagnosis of posterolateral corner (PLC) injuries often relies on the dial test, given the limited detection of these lesions on magnetic resonance imaging, and the incidence of concomitant PLC injury is uncertain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose\/Hypothesis:<\/jats:title>\n                    <jats:p>The purpose of this study was to evaluate rotational subluxation patterns and to identify factors associated with a positive dial test.

Three-dimensional models reconstructed from postoperative computed tomography were registered to preoperative stress radiographs. Posterior translation was assessed by measuring posterior tibial translation (PTT) of each compartment and side-to-side difference (STSD) on both radiographs and models. Rotational subluxation patterns were classified using the medial-lateral difference in side-to-side PTT changes. Clinical outcomes, distribution of suspected PLC involvement, and factors associated with dial test were assessed according to rotational subluxation patterns.

Posteromedial subluxation (93 cases; 73.2%) was more prevalent than posterolateral laxity (34 cases; 26.8%) when compared with the contralateral side. Rotational laxity was greater in posteromedial subluxation than posterolateral subluxation (median, 5.07 vs 1.66 mm;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .03).
