The demand for total knee arthroplasty (TKA) in older patients is increasing. Current perceptions regarding risks may result in patients inappropriately being denied surgery. This study aimed to evaluate TKA outcomes in patients aged ≥80 compared to a younger cohort. This study retrospectively analysed prospectively collected data from the Scottish Arthroplasty Project. Data were extracted for all patients undergoing primary TKA between 2000 and 2019 in two age groups: 1) ≥80 and 2) 50–79. Hybrid and partial knee replacements and those with incomplete data were excluded. Data were extracted on post-operative complications, infection within 1 year, mortality and revision at any point.Abstract
