Lifetime Risk of Primary Shoulder Arthroplasty From 2008 to 2017: A Population-Level Analysis Using National Registry Data

Abstract

OBJECTIVE: To estimate the lifetime risk of primary shoulder arthroplasty in Australia and to examine changes over time. METHODS: For this retrospective population-level analysis, de-identified individual-level data on all primary partial shoulder arthroplasty (PSA) and total shoulder arthroplasty (TSA) procedures performed in Australia from 2008 to 2017 (n = 38,868) were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Population data and life tables were obtained from the Australian Bureau of Statistics. Lifetime risk of primary shoulder arthroplasty was calculated for each year using a standardized formula. Separate calculations were undertaken by ..
