A comparison of noise in ceramic-on-ceramic (CoC) bearings and metal-on-polyethylene (MoP) bearings after total hip arthroplasty (THA) was undertaken. Noise associated with MoP implants is rarely reported and has not been linked to squeaking.
A noise characterising hip questionnaire and Oxford Hip Score (OHS) was sent to 1,000 THA patients; there were 509 respondents 282 CoC and 227 MoP; mean age 63.7 years (range 45-92 years), mean follow up 33 months (range 6-156 months).
Of 282 repsondents 47 (17%) of the CoC patients reported noise compared to 19 (8%) of the MoP patients (p = 0.048); 9 CoC patients and 4 MoP patients reported squeaking. Overall, 27% patients with noise reported avoiding recreational activities because of it and patients with noisy hips scored on average 5 points less on the OHS (CoC: p = 0.04 and MoP: p = 0.007).
This is the first study to report squeaking from MoP THAs. The squeaking hip phenomenon is not exclusive to CoC THAs. Noisy hip implants may have social implications, and patients should be aware of this. We have shown a relationship between noise and a lower OHS. However, longer follow-up is needed to link noise to a poorly functioning implant.
对全髋关节置换术（THA）后陶瓷对陶瓷（CoC）轴承和金属对聚乙烯（MoP）轴承中的噪音进行了比较。与MoP植入物相关的噪音鲜有报道，且未与吱吱声联系起来。
向1000名THA患者发送了一份关于髋关节噪音特征的问卷和牛津髋关节评分（OHS）；有509名受访者，其中282名使用CoC轴承，227名使用MoP轴承；平均年龄63.7岁（范围45 - 92岁），平均随访33个月（范围6 - 156个月）。
在282名受访者中，47名（17%）CoC患者报告有噪音，而MoP患者中有19名（8%）报告有噪音（p = 0.048）；9名CoC患者和4名MoP患者报告有吱吱声。总体而言，27%有噪音的患者表示因噪音而避免参加娱乐活动，髋关节有噪音的患者在OHS上的平均得分比无噪音患者低5分（CoC：p = 0.04，MoP：p = 0.007）。
这是第一项报告MoP全髋关节置换术出现吱吱声的研究。髋关节吱吱声现象并非CoC全髋关节置换术所特有。有噪音的髋关节植入物可能会产生社会影响，患者应该对此有所了解。我们已经表明噪音与较低的OHS之间存在关联。然而，需要更长时间的随访来确定噪音与功能不佳的植入物之间的联系。
