ABSTRACT
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.
