BACKGROUND
We analysed the long-term revision rate, clinical outcomes and metal ion concentrations in blood over time in patients who had undergone metal-on-metal Articular Surface Replacement (ASR) hip arthroplasty.
METHODS
A total of 38 patients (43 hips) were included: 24 patients (28 hips) underwent large-head total hip arthroplasty (XL THA), and 14 patients (15 hips) underwent hip resurfacing arthroplasty (HRA). The median follow-up time was 11 (range 7-12) years.
RESULTS
None of 15 HRA implants were revised. Nine of 28 XL THA implants (32%) in 8 patients were revised. The Co ion levels significantly increased in the XL THA group (p=0.009) over a median time period of 84 (25-97) months.
CONCLUSION
The levels of Co ions in blood were higher in the patients who had undergone XL THA and increased significantly over time.
背景
我们分析了接受金属对金属关节表面置换（ASR）髋关节置换术患者的长期翻修率、临床结局以及血液中金属离子浓度随时间的变化情况。
方法
共纳入38例患者（43髋）：24例患者（28髋）接受大头全髋关节置换术（XL THA），14例患者（15髋）接受髋关节表面置换术（HRA）。中位随访时间为11年（范围7 - 12年）。
结果
15例HRA植入物均未翻修。8例患者中28例XL THA植入物有9例（32%）进行了翻修。XL THA组钴离子水平在中位时间84个月（25 - 97个月）内显著升高（p = 0.009）。
结论
接受XL THA的患者血液中钴离子水平较高，且随时间显著升高。
