Abstract

The aim of this study was to assess the costs and effectiveness of selective short magnetic resonance imaging MRI in patients with acute knee injury. A model was developed to evaluate the selective use of MRI in patients with acute knee injury and no fracture on radiography based on the results of a trial in which 208 patients were randomized between radiography only and radiography plus MRI. We analyzed medical diagnostic and therapeutic costs, quality of life, duration of diagnostic workup, number of additional diagnostic examinations, time absent from work, and time to convalescence during a 6-month follow-up period. Quality of life was lowest EuroQol at 6 weeks 0.61 95% CI 0.54–0.67; duration of diagnostic workup, absence from work, and time to convalescence were longest; and the number of diagnostic examinations was largest with radiography only. These outcomes were more favorable for both MRI strategies EuroQol at 6 weeks 0.72 95% CI 0.67–0.77 for both. Mean total costs were 2,593 euros 95% CI 1,815–3,372 with radiography only, 2,116 euros 95% CI 1,488–2,743 with radiography plus MRI, and 1,973 euros 95% CI 1,401–2,543 with selective MRI. The results suggest that selective use of a short MRI examination saves costs and potentially increases effectiveness in patients with acute knee injury without a fracture on radiography.
