Medical ceramics are frequently used biomaterials as a liner in total hip arthroplasty. Strong efforts have been made to improve material properties over the last decades. Alumina toughened zirconia ceramics seem to be promising alternatives to further reduce fracture rates and squeaking phenomena. To answer the question if alumina toughened zirconia ceramic liners in combination with a cementless, hemispheric cup are able to reduce squeaking phenomena and fracture rates, we initiated a bicentric, mid-term trial. Noise phenomena will be recorded using MONA Score (Melbourne Orthopaedic Noise Assessment). Functional outcome (Harris Hip Score, University of California-Los Angeles, Forgotten Joint Score, EQ-5D Score, Visual Analogue Scale) and radiographic parameters will serve as secondary parameters. The study has been set up for 5 years, with follow-ups after 6-14 weeks, 12, 24 and 60 months.
医用陶瓷作为全髋关节置换术中的衬垫，是常用的生物材料。在过去几十年里，人们为改善材料性能付出了巨大努力。氧化铝增韧氧化锆陶瓷似乎是进一步降低骨折率和摩擦音现象的有前景的替代品。为了回答氧化铝增韧氧化锆陶瓷衬垫与无水泥半球形髋臼杯结合是否能够减少摩擦音现象和骨折率这一问题，我们启动了一项双中心中期试验。将使用莫纳评分（墨尔本骨科噪声评估）记录噪声现象。功能结果（Harris髋关节评分、加利福尼亚大学洛杉矶分校评分、遗忘关节评分、EQ-5D评分、视觉模拟评分）和影像学参数将作为次要参数。该研究设定为期5年，在6-14周、12个月、24个月和60个月后进行随访。
