Objective: To analyze menisco-tibial and femoro-tibial translation
patterns in healthy and ACL-deficient knees in different knee
flexion angles under muscle activity. Methods: The ACL-deficient
and contralateral healthy knees of 10 patients were examined with
an open MR system at 30° and 90° of knee flexion, under both
flexing and extending, isometric muscle activity. Translations
between the tibia, the femoral condyles and the menisci were
analyzed by three-dimensional image postprocessing. Results:
Posterior translation of the femur and menisci relative to the
tibia occurred during knee flexion (30°-90°). In ACL-deficient
knees, posterior translation of the medial femoral condyle
(+1.3±3.8 mm) was significantly larger than in healthy knee
(-0.9±2.9 mm; p
