Physical fitness and mental health 'can affect costs associated with knee replacement'

23 June 2016

A new study has indicated that a person's physical fitness and mental state can affect the costs associated with providing total knee replacement (TKR) for these individuals.

The University of Texas research involved a six-month prospective cohort study of patients with knee osteoarthritis who underwent TKR, including 212 patients, of whom 66 percent were women.

Mean total TKR-related costs were $30,831 (£20,820), with analysis published in the Journal of Rheumatology showing that increasing body mass index (BMI) scores and higher anxiety levels were associated with increased costs.

Decreasing levels of positive social interactions also had a negative impact. A lower cost scenario with a lower range of normal BMI, the highest positive social interactions and no anxiety predicted TKR costs to be $22,247, whereas for obese patients with the lowest positive social interactions and highest anxiety, the estimate went up to $58,447.

The researchers concluded: "Increased baseline BMI, anxiety and poor social support lead to higher TKR-related costs in patients with knee osteoarthritis. Preoperative interventions targeting these factors may reduce TKR-related costs, and therefore be cost-effective."
