The effect of BMI and other factors on post-operative length of stay: A multivariable regression analysis of 860 patients undergoing total knee arthroplasty

Demand for hip and knee arthroplasty has increased year on year [1], and this trend is predicted to continue due to unmet need, increasing obesity, and longer life expectancy [2]. There is a trend towards minimising length of stay (LOS) after total knee arthroplasty (TKA), as increased LOS is associated with increased complication and readmission rates, worse 1-year patient-related outcome measures (PROMS) scores, and higher costs [3 –6]. In some studies, day case arthroplasty has been shown to be beneficial compared with inpatient arthroplasty for both the hip and knee [7–9].
