| Popis: | 105 Deformities of the knee joint in the children sometimes extend beyond the physiological limit to produce symptoms. Factors including family history, bone dysplasia, Blount’s disease, Rickets, fracture, and trauma would interfere with the normal angular alignment of the lower limbs. Corrective procedures for the angular deformities of the knees were needed to achieve equal limb lengths, neutral mechanical axes, and horizontal knees by skeletal maturity. The guided growth surgery which enable the hemiepiphyseal arrest to achieve the angular correction. The aims of the current study were to evaluate the performance and lower limb joint kinematics and kinetics in the patients receiving guided growth surgery for correction bilateral valgus knee. It was hoped that a complete knowledge of the general outcome and factors influencing the performance of the guided growth surgery could be established, which would be helpful for future clinical decision-making. It was hypothesis that these patients who receiving guided growth surgery would show decreased step width, lower abduction angle of knee and ankle. These patients would also show decreased adduction angle of hip and greater abductor moment of knee. The postoperative group was found displayed decreased the step width. The angle and moment of hip and knee on gait were improved in frontal plane. However, the angle and moment were not improved in sagittal plane. The angle of the ankle was not improved in frontal plane. It is suggested that the position of implant should be meticulous, the deformity of the ankle should be considerate and the patients could do exercise training to strengthen the muscle of lower limbs. |
