Suspected peroneal tendinopathy, tears, and subluxation are often confirmed preoperatively using magnetic resonance imaging (MRI) or diagnostic ultrasound (US). No study has directly compared the accuracy of these tests for the diagnosis of peroneal tendon pathology. The purpose of this study is to directly compare MRI and US to intraoperative findings in patients who underwent surgery for suspected peroneal pathology to determine the imaging diagnostic accuracy. Operative records and diagnostic images for 21 consecutive patients who had both MRI and US prior to surgery for suspected peroneal tendinopathy, tears, or subluxation were retrospectively reviewed. The results of this review are compared with the intraoperative findings to yield the sensitivity and specificity for each imaging modality. For the diagnosis of peroneal tendon tears, US was found to have a sensitivity of 88% and specificity of 100%, compared to 100% sensitivity and specificity for MRI. In the diagnosis of peroneal tendinopathy, both US and MRI had a sensitivity and specificity of 100%. In diagnosing peroneal subluxation, US was 100% sensitive compared to 66% for MRI, and both were 100% specific. In conclusion, US was found to be more effective in diagnosing peroneal subluxation and MRI was slightly more accurate in the diagnosis of peroneal tendon tears.
