Description of the Motion of the Knee in a Patient with a bilateral anterior cruciate tear. Technical Note

Abstract

Tibial rotation and migration of the tibiofemoral contact point along the tibial plateau during the motor task of climbing a step of 17 cm of height differ between measurements taken in an individual with bilateral anterior cruciate ligament full injury and those of a healthy volunteer. During step negotiation the mean rotation of both lower limbs changes from 25° to 14° and the healthy volunteer 20° to 5°. The contact point migration changes from (bilateral injury) 30% to 45% and (healthy) 45% to 80%. These measurements of 3D stereophotogrammetry and videofluoroscopy (CINARTRO) allow to performance an evaluation of the dynamic function of the knee for a functional diagnosis and follow up and rehabilitation with greater accuracy and efficiency than in the absence of this objective evaluation.
