Análise comparativa da marcha com três joelhos protéticos diferentes, em amputado transfemoral esquerdo Comparative analysis of gait with three different prosthetic knees, in patient with left transfemoral amputation

The term amputation is the partial or total removal of a limb. The transfemoral amputation refers to amputation performed between the dislocation of the knee and hip. The National Social Security Institute (INSS) professionally rehabilitates disabled beneficiaries, returning to their professional activity, for example, those with sequelae of amputation. The prosthetic knees provide stability in the stance phase and control in the swing phase during gait. The objective was to analyze gait of a patient with left transfemoral amputation using three different prosthetic knees (rotary hidraulic, hydraulic and monocentric microprocessor). Helen Hayes markers set were used, after the patient walked a determined path to capture the movements, with the three knees, so the kinematic and observational analysis could be performed. The evaluation showed observational gait characteristics with the three knees very similar. Was observed in the kinematic analysis parameters of spatiotemporal gait with smaller values than the references in the three knees, in consequence of lack of security of the knee amputation prosthesis. The microprocessor knee showed a larger number of parameters in the two limbs due to ease alignment and adjustment. It was concluded that the microprocessor knee is the most suitable for this patient.
