Incision Suture Technique After Total Hip and Knee Arthroplasty

Total hip arthroplasty and total knee arthroplasty (THA and TKA) are surgeries to replace severely damaged hip and knee joints in the human body by artificial joints. THA and TKA can significantly alleviate the pain of the patient’s joints, improve function and the quality of life. As China is gradually becoming an aging society, according to the figures published by the National Bureau of Statistics of China, as of 2019, the data on the elderly population in our country is: the population over 60 years old account for 17.9% of the total population, and is growing rapidly at a rate of nine million per year; the population over 65 years old account for 12.6% of the total population. In 2022, it will become a deep aging society with the percentage of more than 14%, a super-aging society with the percentage of more than 20% in 2033, and then continue to rapidly increase to about 35% in 2060. Due to the large basic population, China has a huge number of the elderly population, and the number of elderly patients suffering from bone and joint diseases is increasing year by year, and the demand for THA and TKA is also gradually increasing. Kurtz et al. (J Bone Joint Surg Am 89(4):780–785, 2007) predicted in 2007 that the demand for hip and knee arthroplasty in the United States in 2020 would reach 380,000 and 1,520,000, and by 2030, it would reach 570,000 and 3,480,000. According to statistics from Professor Weng Xisheng of Peking Union Medical College Hospital, the number of hip and knee arthroplasty in China in 2019 was 577,000 and 375,000 respectively, an increase of 31% and 50% compared with 2018.
