Noisy ceramics bearing surfaces are a recently recognized problem in total hip arthroplasty. Component malposition as a potential cause has been proposed. Squeaking occurred in 28 (2.7%) of 999 patients undergoing ceramic on ceramic total hip arthroplasty at our institution. Patients were matched, in a 1:2 ratio by anthropometric and demographic variables and also prosthesis size and type. The acetabular position was measured using radiographs and computed tomography. There was no statistically significant difference in cup inclination (P = .25) or version (P = .38) between groups. Four hips that have been revised were available for retrieval analysis. Stripe wear and metal transfer to ceramic components were observed. Etiology of squeaking ceramic total hip arthroplasty remains elusive. Although malposition could be an important contributing factor, the latter cannot be the sole reason based on our findings. Further investigation to elucidate the etiology is warranted.
在全髋关节置换术中，陶瓷轴承表面产生噪音是一个最近才被认识到的问题。有人提出组件位置不当是一个潜在原因。在我们机构接受陶瓷对陶瓷全髋关节置换术的999例患者中，有28例（2.7%）出现了吱吱声。根据人体测量学和人口统计学变量以及假体尺寸和类型，以1:2的比例对患者进行匹配。使用X线片和计算机断层扫描测量髋臼位置。两组之间的髋臼倾斜度（P = 0.25）或髋臼旋转（P = 0.38）没有统计学上的显著差异。有四个已翻修的髋关节可供取出分析。观察到条纹磨损和金属转移到陶瓷组件上。陶瓷全髋关节置换术出现吱吱声的病因仍然不明。尽管位置不当可能是一个重要的促成因素，但根据我们的研究结果，后者不可能是唯一的原因。有必要进行进一步调查以阐明病因。
