We administered the Slocum anterolateral rotatory instability test in the open magnetic resonance imaging scanner and scanned the sagittal view of the knee. The anterior displacements of the tibia at the medial and lateral compartments were measured. Furthermore, we examined 14 anterior cruciate ligament\u2014deficient knees twice to assess intraobserver and interobserver reproducibility and evaluated the difference and interclass correlation coefficient of 2 measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the anterior cruciate ligament\u2014deficient knee, displacement was 14.4 \u00b1 5.5 mm at the lateral compartment and 1.6 \u00b1 2.3 mm at the medial compartment; in the normal knee, displacement was 0.7 \u00b1 1.9 mm and \u20141.1 \u00b1 1.2 mm, respectively. The difference and interclass correlation coefficient between 2 repeated measures at the lateral compartment were 1.0 \u00b1 0.7 mm and .98 for intraobserver reproducibility and 1.1 \u00b1 0.7 mm and
