    Background and Study Aim: In this study, focusing on the individual difference in the characteristics of the knee joint, which plays an important role in weight bearing during walking, we examined the relationship between difference in knee alignment and pain in the legs during walking and effect of the pain on the psychological state of exercise performers. Material/Methods: A total of 40 subjects, including 25 healthy men and 15 women were recruited to this study. Knee alignment was classified according to the intercondylar and intermalleolar distances by increments of 2.0 cm. After walking (85km) on day 3 of the 5-day event, subjects were required to answer a questionnaire asking where in the leg they had pain. The psychological state of each subject was assessed by performing the Profile of Mood States (POMS) after they had rested after walking on each of days 1, 2 and 3 of the 5- day event. Results: The following sites exhibited significant differences in the number and incidence of injury between groups: the anterior side of lower leg (p <0.05), posterior side of lower leg (p <0.01), ankle joint (p <0.05) and sole of foot (p <0.01). In the genu valgum group, the score for factor V(:Vigor) decreased by 4.0 points between days 1 to 3: 18.1 ± 4.6 points on day 1 and 14.1 ± 7.6 points on day 3, with a significant difference between days 1 and 3. Conclusions: When performing an exercise that places load on the legs, such as walking, one should consider the risk of injury by measuring the individual’s knee alignment before commencing the exercise.

    Opis:
    Blount’s disease, or tibia vara, is the most common cause of pathologic genu varum in children and adolescents. Changes in the loading of knee structures such as tibial articular cartilage, menisci and subcondral bone are well documented in case of genu varum. But the mechanical effects of this condition on foot bones are still questionable. In this study, the authors hypothesized that stress distributions on foot bones might increase in patients with tibia vara when compared with patients who had normal lower extremity mechanical axis. Three-dimensional (3D) finite element analyses of human lower limb were used to investigate and compare the loading on foot bones in normal population and patient with tibia vara. The segmentation software, MIMICS was used to generate the 3D images of the bony structures of normal and varus malalignment lower extremity. Except the spaces between the adjacent surface of the phalanges fused, metatarsals, cuneiforms, cuboid, navicular, talus and calcaneus bones were independently developed to form foot and ankle complex. Also femur, tibia and fibula were modeled utilizing mechanical axis. ANSYS version 14 was used for mechanical tests and maximum equivalent stresses (MES) were examined. As a result of the loading conditions, in varus model MES on talus, calcaneus and cuboid were found higher than in normal model. And stress distributions changed through laterally on middle and fore foot in varus deformity model.
