Total Hip Arthroplasty (THA) is an effective treatment for severe hip arthritis, with patients reporting high rates of satisfactory results postoperatively. There are a variety of choices regarding THA implant designs. Ceramic on Ceramic and Ceramic on Highly Cross-Linked Polyethylene (XLPE) THAs are the materials of choice nowadays. The purpose of this study is to review the effect of kinematics and kinetics on wear (in vivo and in vitro testing) that affect wear in Ceramic on Ceramic and Ceramic on XLPE total hip arthroplasties and identify possible advantages amongst them. The study hypothesis was that THA kinematics and/or kinetics, since they directly affect THA wear, could provide data for possible advantages between the examined implant designs. A systematic review of the literature identified no significant evidence for biomechanical advantages between these two prostheses in terms of wear. Further research is proposed with the use of gait analysis systems combined with surface electromyography to further investigate THA biomechanics at a laboratory set up. Wearable sensors technology could also identify detailed biomechanical parameters in more complex daily activities.

陶瓷上的陶瓷和 XLPE 上的陶瓷磨损的生物力学评估

全髋关节置换术 (THA) 是治疗严重髋关节炎的有效方法，患者报告术后满意结果的比例很高。关于 THA 植入物设计有多种选择。陶瓷上的陶瓷和高度交联聚乙烯 (XLPE) 上的陶瓷 THA 是当今的首选材料。本研究的目的是回顾运动学和动力学对磨损的影响（体内和体外测试）影响陶瓷对陶瓷和陶瓷对 XLPE 全髋关节置换术的磨损，并确定它们之间可能的优势。研究假设是 THA 运动学和/或动力学，因为它们直接影响 THA 磨损，可以为所检查的植入物设计之间可能的优势提供数据。对文献的系统评价没有发现这两种假体在磨损方面的生物力学优势的显着证据。建议使用步态分析系统结合表面肌电图进行进一步研究，以进一步研究实验室设置的 THA 生物力学。可穿戴传感器技术还可以识别更复杂的日常活动中的详细生物力学参数。
