Two types of anaesthesia and length of hospital stay in patients undergoing unilateral total knee arthroplasty (TKA): A secondary analysis based on a single-centre retrospective cohort study in Singapore

Evidence regarding the relationship between the type of anaesthesia and length of hospital stay is controversial. Therefore, the objective of this research was to investigate whether the type of anaesthesia was independently related to the length of hospital stay in patients undergoing unilateral total knee arthroplasty (TKA) after adjusting for other covariates.
