摘要：The gait of 20 patients with unilateral hip disease, who underwent total hip arthroplasty (THA), was analyzed preoperatively and 12 months after a unilateral THA, using a zebris ultrasound-based three-dimensional motion analysis system. The constant gait speed was 2.5 km/h. The spatial-temporal and angular parameters were compared to the gait parameters of 20 healthy, elderly subjects. The aim of this study is to determine how selected gait parameters may change as a result of total hip arthoplasty at a constant gait speed. Before the THA, asymmetry was observed in spatial-temporal parameters, in the range of hip motion, maximum hip flexion, maximum hip extension, as well as in knee motion. Therefore, it was suggested that the increased motion of the opposite hip and knee was a compensatory function. The study showed that increased pelvic obliquity and flexion-extension occurred as compensation. It seems that the range of pelvic rotation was not involved, even in our patients with unilateral osteoarthritis of the hip joint. At 12 months after the THA, no asymmetry of spatial-temporal parameters and of the knee and hip joint motion could be observed, and the increased pelvic motion also became less significant. Therefore, this study suggested that the THA could reverse the adverse influence on other joints prior to the symmetrical normalization of hip motion.
