Studie från 2022 som jämför cortisoninjektioner kontra fysioterapi vid knäartros och räknar på hälsoekonomi och QALY. Konklusion: "A course of physical therapy was cost-effective compared with a course of glucocorticoid injections for patients with knee osteoarthritis. These results suggest that, although the initial cost of delivering physical therapy may be higher than an initial course of glucocorticoid injections, 1-year total knee-related costs are equivalent, and greater improvement in QALYs may justify the initial higher costs.
