Descriptive analysis of the cost-effectiveness of depressed patients undergoing total knee arthroplasty: an economic decision analysis

Conclusions Our study might help policy-makers and clinicians identify which types of patients benefit most from TKA and then advise high-risk patients (high-level depression status in this study) about how to recovery better with limited resource allocation. Preoperative evaluation of patients' psychological state may decrease unnecessary economic burdens and suffering during the recovery period.
