MR diagnosis of meniscal tears of the knee: analysis of error patterns.

Purpose: Despite high accuracy of magnetic resonance imaging (MRI) for diagnosing meniscal tears, MR findings do not always agree with surgical findings. We performed a blinded, retrospective study to analyze the nature and frequency of errors in the MR diagnosis of meniscal tears.

Materials And Methods: Medical records of 100 consecutive patients who underwent MR and arthroscopy of the knee at our institution were reviewed.
