Abstract

Today, rupture of the anterior cruciate ligament is the most common heavy injury in athletes, but it can also occur in sedentary subjects. Its treatment, always adapted to the lifestyle, age and will of the patient, often remains surgical. However, despite its frequency and universality, there are still walking disorders following the operation. These disorders sometimes persist for several months, or even several years after surgery. The present study is therefore interested in determining the risk factors linked to walking disorders following reconstruction of the anterior cruciate ligament. The objective of this study is to determine what risk factors associated with walking disorders are after reconstruction of the anterior cruciate ligament by hamstring graft. This study focused on factors that may exist at 3 and 6 months postoperatively. Two populations participated in this study, a healthy population and a population having benefited from reconstruction of the anterior cruciate ligament. The operated test group is divided into two subgroups, one with a postoperative period of 3 months and the second at 6 months. All subjects were subjected to the same protocol, their gait on the treadmill was analyzed and evaluated with an Optogait® analysis system. A univariate analysis was carried out first. Then, a multivariate analysis by adjustment method was carried out in order to eliminate the potential confounding factors. The comparison of the results between the populations in the univariate analysis shows an absence of significant results however there are trends. The statistical results of the multivariate analysis showed interactions in the two subgroups of the operated population.In fact, it turns out that at 3 months there is a tendency to worse gait disorders in subjects with a high BMI reflecting overweight, when an associated surgical procedure has taken place on the meniscus, in subjects over 35 years of age and males. On the other hand, at 6 months, the tendency to worsening is visible only in the strata represented by subjects with a BMI corresponding to overweight, as well as in subjects having benefited from a meniscal suture associated with ACL reconstruction. .The results of the present study show that there are certain factors which tend to increase the risk of these walking disorders after reconstruction of the anterior cruciate ligament by hamstring graft, these factors are different depending on the time postoperative.
