title: Assessment of gait after bilateral hip replacement. Case study.
abstract: Total hip arthroplasty (THA) is one of the most effective methods of treatment of severe hip osteoarthritis (HOA). In many cases pathological gait patterns persist despite properly conducted surgery and disturb the normal wear of the artificial joint surfaces. The aim of the study was to conduct functional and biomechanical assessment of gait in a patient after bilateral THA due to severe degenerative changes in the hip. The assessment focused on the gait parameters which significantly deviate from a normal gait pattern at various stages of treatment. Physiotherapeutic assessment of the patient included measurements of the range of motion in lower limb joints, the Timed Up and Go test, and pain assessment. Biomechanical assessment involved measurements of spatiotemporal gait parameters and the dynamic range of motion using BTS Smart-E motion analysis system. Although clinical examinations after both the first and second procedure suggested recovery of the patient's physical function, biomechanical assessment of her gait after the second procedure indicated the presence of deviations from a normal gait pattern. Secondary to a limited range of internal/external hip rotation, extension, and abduction, corresponding indices were still in the pathological range.
