Noting that TKA is typically done for advanced degenerative changes, MRI should rarely be indicated in the preoperative period for this procedure. Nonetheless, this study found that MRI was done within the year before TKA for 7.68% of the study cohort. In an era striving for evidence-based medicine, the almost $45 million dollars spent on MRI in the year before TKA may represent overutilization.
