Background. ACL rupture and reconstruction may lead to impairment of spatiotemporal and kinematic gait parameters. The purpose of this study was to evaluate patient’s gait following a complete tear of the ACL and its endoscopic reconstruction. Material and methods. 3D gait analysis was performed using the BTS Smart optoelectronic system (6 IR cameras, 120 Hz). The study group included 40 patients with complete unilateral ACL rupture and 37 healthy matched subjects. In the study group gait analysis was performed twice, within one to two weeks prior to the ACL reconstruction and the follow-up study six months after surgery. In the control group single gait analysis was performed. Results. Six months after the ACL reconstruction the duration of the stance phase for the non-operated limb (p<0,0000) and the initial double stance phase for the operated limb (p<0,0000) were reduced. A statistically significant increase in the step length for both lower limbs was observed. Additionally patients gait cadence (p=0,0003) and mean gait speed (p=0,0006) have also increased. Nevertheless, in the second study, these parameters were still significantly different comparing to the control group. Analysing the kinematic parameters of patients” gait after surgery it was demonstrated, that the hip and knee joints range of motion in both limbs has increased in a statistically significant way. The range of motion of the ankle joint of the operated limb has also improved. Conclusions. 1. Within six months after the ACL reconstruction there was significant improvement and normalization of the patient’s gait pattern, though we may still observe significant differences when compared to the control group, which indicates the need for further rehabilitation focused on the re-education of patients gait pattern. 2. Results of our study indicates a need of long-term observation in the group of patients after ACL reconstruction to determine, whether the gait pattern impairment demonstrate further tendency to improve in time.
