2011至2019年中国人工髋膝关节置换手术量的初步统计与分析

Reports and analysis of amount of hip and knee arthroplasty in China from 2011 to 2019

摘要:

目的:探讨全国范围内2011至2019年髋关节置换和膝关节置换年手术量及数据变化趋势。方法:采用自行设计的问卷及便利抽样方式调查2011至2019年在国内销售的人工关节产品年销售数量,每年调查1次。北京市的数据由北京地区所有二级以上医院的关节科主任或秘书填报,全国的数据由人工髋、膝关节假体制造商和经销商的市场部或销售部负责人填报。数据收集后分析年手术总量、年增长率及髋、膝关节假体构成比。结果:共发放问卷541份,回收率87.2%。2011至2019年(2015年空缺)全国髋关节置换(包括全髋关节置换和股骨头置换)及膝关节置换(不包括单髁关节置换)年手术总量分别为221 920、250 473、328 192、437 100、455 640、567 397、688 583、951 986例次;年增长率2012至2014年分别为12.87%、31.03%和33.18%,2017至2019年分别为24.52%、21.36%和38.25%,年均增长率为19.96%。2011至2019年(2015年空缺)全国髋关节假体(国产及进口)占假体总量(不包括单髁关节假体)的比例分别为75.72%、72.61%、67.73%、64.74%、62.47%、65.04%、62.78%和59.44%;国产髋膝关节假体占髋膝关节总量的比例分别为33.15%、39.27%、32.26%、45.16%、42.19%、47.55%、54.33%和55.97%。2011至2019年北京市髋膝关节置换年手术总量分别为11 077、12 005、16 822、18 147、19 102、19 247、18 467、20 258、21 381例次;2012至2019年年增长率分别为8.38%、40.12%、7.88%、5.26%、0.76%、-4.10%、9.76%、5.54%,年均增长率为8.56%。北京市髋关节假体(国产及进口)占北京市髋膝关节总量(不包括单髁关节假体)的比例分别为48.26%、48.90%、46.54%、46.17%、46.33%、45.31%、43.33%、41.64%和43.66%。结论:2011至2019年全国人工髋膝关节置换进入快速增长阶段,国产假体市场占有率逐年增大,北京市人工髋膝关节置换因医疗资源饱和而进入平台期。

Objective:To investigate the annual amounts of knee and hip arthroplasty in China and their changing trends.Methods:Self-designed questionnaires were conducted by convenience sampling to investigate the annual sales of all brands of artificial joints in China from 2011 to 2019. The data in Beijing were collected from the joint department in all the secondary and tertiary hospitals in Beijing. The national data were collected from the principal of marketing department or sales department of the manufacturer. Statistical analysis was performed subsequently.Results:The number of questionnaire was 541 with recovery rate 87.2%. The annual amounts of knee and hip arthroplasty in China between 2011 and 2019 were 221,920 (2011), 250,473 (2012), 328,192 (2013), 437,100 (2014), 455,640 (2016), 567,397 (2017), 688,583 (2018), 951,986 (2019) respectively. However, the 2015 data was missing. The annual growth rates were 12.87% (2012), 31.03% (2013), 33.18% (2014), 24.53% (2017), 21.36% (2018), 38.25% (2019). The average of annual growth rate between 2011 and 2019 was 19.96%. Amongst the total amounts of joint arthroplasty in China, hip prosthesis (domestic and imported) accounted for 75.72% (2011), 72.61% (2012), 67.73% (2013), 64.74% (2014), 62.47% (2016), 65.04% (2017), 62.78% (2018) and 59.44% (2019), while the domestic prosthesis (hip and knee) engaged 33.15% (2011), 39.27% (2012), 45.16% (2014), 42.19% (2016), 47.55% (2017), 54.33% (2018) and 55.97% (2019). The annual amounts of THA and TKA in Beijing between 2011 and 2019 were 11,077 (2011), 12,005 (2012), 16,822 (2013), 18,147 (2014), 19,102 (2015), 19,247 (2016), 18,467 (2017), 20,258 (2018), 21,381 (2019). The annual growth rates were 8.38% (2012), 40.12%(2013), 7.88% (2014), 5.26% (2015), 0.76% (2016), -4.10% (2017), 9.76% (2018), 5.54% (2019). The average of annual growth rate between 2011 and 2019 was 8.56%. Amongst the total amounts of joint arthroplasty in Beijing, hip prosthesis (domestic and imported) accounted for 48.26% (2011), 48.90% (2012), 46.54% (2013), 46.17% (2014), 46.33%(2015), 45.31%(2016), 43.33% (2017), 41.64% (2018) and 43.66% (2019).Conclusion:The total amounts of joint arthroplasty reached up to 951,986 in 2019 with the average annual growth rate of 19.96% between 2011 and 2019. The national amount of hip and knee arthroplasty increased stably, while the amount of hip and knee arthroplasty in Beijing grew slowly. The number of hip arthroplasty was more than that of knee arthroplasty nationwide, while the trend was converse in Beijing. Domestic prosthesis had a higher growth rate than imported prosthesis. The amount of domestic prosthesis surpassed that of imported prosthesis from 2018.
