全髋关节置换术（THA）是治疗严重髋关节骨关节炎（HOA）最有效的方法之一。在许多情况下，尽管进行了适当的手术，病理步态模式仍然存在，并扰乱了人工关节表面的正常磨损。本研究的目的是对因髋关节严重退行性改变而行双侧THA术后患者的步态进行功能和生物力学评估。评估的重点是在不同治疗阶段明显偏离正常步态模式的步态参数。患者的物理治疗评估包括下肢关节活动范围的测量、Timed Up and Go测试和疼痛评估。生物力学评估包括使用BTS Smart-E运动分析系统测量时空步态参数和运动动态范围。虽然第一次和第二次手术后的临床检查表明患者的身体功能恢复，但第二次手术后对其步态的生物力学评估表明存在与正常步态模式的偏差。继发于髋关节内/外旋、伸展和外展范围有限，相应指标仍在病理范围内。
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.
