Abstract
Spatio-temporal analysis of gait is a measurement of certain aspects of walking, which are the length of the step, the unipodal or bipodal support time (and consequently the oscillating phase time) or still the load and step propulsion phase. This quantitative examination is now accessible in clinical practice, thanks to certain accessories such as the OptoGait. This tool allows, among other skills, a clear and concise analysis of certain aspects of the gait. After rupture of the ACL, the proprioceptive sensory afferents of the knee are reduced by the disappearance of the so-called ligament, very rich in mechanoreceptor; even if at present this deficit is not quantified. The proprioceptive deficit is revealed when the limb is solicited in daily activities in a static position and during dynamic movements and even more so during sports activities. Laboute, in 2016, explains that "the use of the platform of force constitutes the gold standard of the postural evaluation”. LCA laximetry is a way to follow the evolution of ligamentization of the neotransplant in a simple and fast way by a rigorously reproducible examination. It allows to continue or to reorient the rehabilitation by objective analysis. GNRB laximetry remains a reliable instrument with an estimated sensitivity of 70% and a specificity of 99%. Compared to Telos, it is more reproducible and more significant in partial and total ACL ruptures. Thus, it is essential in the quantitative follow-up of the ACL surgery in order to account for the passive stability of the operated knee. At 6 months, isokinetic evaluation of the knee is an essential moment in sports traumatology. Indeed, it seems essential to have a glimpse of active knee stability in order to consider a future pivotal activity. Since the precursory work of Croisier, we know what meaning to give to the values emitted by such a balance sheet. However, many controversies exist on the values to use, so in order to determine the most sensitive, we conducted a review of the international literature. From this synthesis emanate the use of two types of speeds, the index of symmetry, the moment of force associated with the mass of the patient and the ratios.
