Effect of Body Mass Index and Psychosocial Traits on Total Knee Replacement Costs in Patients with Osteoarthritis.

Objective: Clinical and psychosocial attributes are associated with clinical outcomes after total knee replacement (TKR) surgery in patients with osteoarthritis (OA), but their relationship with TKR-related costs is less clear. Our objective was to evaluate the effect of clinical and psychosocial attributes on TKR costs.

Methods: We conducted a 6-month prospective cohort study of patients with knee OA who underwent TKR.

Cost-effectiveness of total knee replacement: a prospective cohort study.

Objective: Total knee replacement (TKR) rates have significantly increased in the past decade. While the procedure itself might be costly, the cost-effectiveness and potential offset costs from patient and societal benefits have not been clearly established. The objective of this study was to perform an economic evaluation of TKR in patients with knee osteoarthritis (OA).
