Imaging the postoperative meniscus.
Patients who have undergone meniscal repair or resection and who develop new symptoms frequently are referred for MR imaging. In the postoperative meniscus, however, the standard MR imaging criteria for meniscal tears cannot be applied to diagnose recurrent or residual tears because signal and shape abnormalities are expected postoperative findings. This article reviews the MR imaging findings that can be used for diagnosing recurrent tears and demonstrates the usefulness of MR arthrography in the evaluation of the postoperative meniscus.
