Shoulder arthroplasty (SA), including hemiarthroplasty, reverse and anatomical total SA (TSA), improves quality of life by reducing shoulder pain and restoring function in patients not only with irreparable rotator cuff tears and/or cuff tear arthropathy but also with osteoarthritis posttraumatic arthritis, proximal humeral fractures, etc. Given the rapid developments in artificial joints and improvements in postoperative outcomes, the number of SA surgeries is increasing worldwide. Therefore, we investigated changes in trends over time in Korea. We analyzed the longitudinal changes in the incidence of SA including anatomic and reverse TSA, hemiarthroplasty, and shoulder revision arthroplasty (SRA) by changes in the Korean age profile, surgical facilities, and geographical regions using the Korean Health Insurance Review and Assessment Service database from 2010 to 2020. Data were also collected from the National Health Insurance Service and the Korean Statistical Information Service. From 2010 to 2020, the TSA rate per 1,000,000 person-years increased from 10.571 to 101.372 (time trend = 1.252; 95% CI 1.233-1.271, P
