Tibial rotation (external\/internal) was imposed with a torque of 2 Nm on the footrest with the ankle locked in dorsiflexion. Anterior translation of the tibia in relation to the femur was measured with a commercially available arthrometer. Measurements were performed in a neutral position, internal rotation, and external rotation. Intrarater and inter\u2010rater reliability was validated in 10 healthy volunteers (Cronbach \u03b1). We examined 10 patients with isolated anterior cruciate ligament (ACL) rupture, as well as 10 patients with ACL rupture plus medial instability and 10 patients with additional lateral instability. Side\u2010to\u2010side differences were used for calculation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Comparison of healthy volunteers and subjects with isolated ACL rupture showed significant differences: internal rotation, 0.79 mm and 2.46 mm, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      = .001); neutral position, 0.4 mm and 3.35 mm, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .0001); and external rotation, 0.29 mm and 2.5 mm, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      = .003).
