Total hip arthroplasty (THA) is a preferred treatment for primary osteoarthritis (OA) or secondary degenerative arthropathy due to developmental hip dysplasia (DDH). Gait analysis is considered a gold standard for evaluating post-arthroplasty walking patterns. This study compared post-THA spatiotemporal gait parameters (SGPs) between OA and DDH patients and explored correlations with demographic and clinical variables. Thirty patients (15 per group) were recorded during gait and their SGPs were analyzed. Functionality was evaluated with the Oxford Hip Score (OHS). The OA patients were significantly older than DDH patients ( < 0.005). Significant and moderate to strong were the correlations between SGPs, age, and four items of the OHS concerning hip pain and activities of daily life (0.31 < Pearson's r < 0.51 all < 0.05). Following THA, both groups exhibited similar levels of the examined gait parameters. Post-arthroplasty SGPs and OHS correlations indicate limitations in certain activities. Given the absence of pre-operative data and the correlation between age and SGPs and OHS, ANCOVA testing revealed that age adjusts OHS and SGP values, while pre-operative diagnosis has no main effect. These findings indicate that hip OA or DDH do not affect postoperative SGPs and patients' functionality. Future studies should examine both kinematic and kinetic data to better evaluate the post-THA gait patterns of OA and DDH patients.
全髋关节置换术（THA）是治疗原发性骨关节炎（OA）或发育性髋关节发育不良（DDH）所致继发性退行性关节病的首选方法。步态分析被认为是评估关节置换术后步行模式的金标准。本研究比较了OA和DDH患者全髋关节置换术后的时空步态参数（SGPs），并探讨了其与人口统计学和临床变量的相关性。记录了30例患者（每组15例）的步态，并分析了他们的SGPs。使用牛津髋关节评分（OHS）评估功能。OA患者比DDH患者年龄显著更大（<0.005）。SGPs、年龄以及OHS中关于髋关节疼痛和日常生活活动的四项之间存在显著且中等至强的相关性（所有0.31<Pearson相关系数r<0.51，均P<0.05）。全髋关节置换术后，两组的检查步态参数水平相似。关节置换术后SGPs与OHS的相关性表明某些活动存在局限性。由于缺乏术前数据以及年龄与SGPs和OHS之间的相关性，协方差分析显示年龄可调整OHS和SGP值，而术前诊断无主要影响。这些发现表明髋关节OA或DDH不影响术后SGPs和患者功能。未来的研究应检查运动学和动力学数据，以更好地评估OA和DDH患者全髋关节置换术后的步态模式。
