%X The Lapidus arthrodesis is a common surgical intervention for hallux valgus aimed primarily at improving pain and functionality in the affected foot. Instrumented motion analysis provides the opportunity to collect objective data on movement behavior. The study aims to examine the extent to which fusion in the first tarsometatarsal joint affects the remaining joints of the lower extremity. In addition, MCID values for specific parameters are to be calculated, providing an objective assessment of functionality and patient satisfaction three months postoperatively. Therefore, 20 patients were examined pre- and postoperatively three months after Lapidus arthrodesis using instrumented motion analysis. The inertial sensor system MTw Awinda was used for the motion analysis of the lower extremity during walking and stair climbing. Specifically, spatiotemporal and kinematic gait parameters of the ankle, knee, and hip joints in the sagittal plane were analyzed. MCID values for the VAS score and the FAAM-G were also obtained for all patients, allowing for a comparison and correlation with the results of the gait analysis parameters.The results of this study confirmed the hypothesis that Lapidus arthrodesis has an impact on the biomechanics of the joints throughout the lower extremity three months postoperatively. This is demonstrated in kinematic parameters, such as reduced walking speed, as well as spatiotemporal parameters, indicating a reduced range of motion in all joints, particularly the ankle. In addition to the altered biomechanics, there is also a decrease in functionality for those patients how underwent a marginal reduction of pain.Nevertheless, this finding is of significant interest as it suggests impaired functionality of the foot due to pain. When compared to existing literature, our results align with previous findings regarding altered spatiotemporal gait parameters and MCID values for VAS and FAAM-G. Furthermore, objective MCID values were calculated for specific clinical situations using various methods and for different gait analysis parameters for the first time. However, determining these values based on larger cohorts is necessary for clinical application.
