Kane PW, et al. - Authors assessed the diagnostic accuracy of magnetic resonance imaging and varus stress radiographs for fibular collateral ligament (FCL) tears. They also compared these modalities to intraoperative findings. The utilization of both varus stress radiographs and MRI in diagnosing FCL injuries was supported in the findings, as for the diagnosis of an acute FCL tear, MRI was more sensitive and in diagnosing a chronic FCL tear, varus stress radiographs are more sensitive. In order to diagnose both acute and chronic FCL injuries, experts recommended both imaging modalities.
