Abstract

Anomalies of the medial meniscus are rare and difficult to diagnose clinically. Among these anomalies, anomalous insertion of the medial meniscus into the anterior cruciate ligament is rare. Most of the reported cases had no relation to clinical symptoms and were found incidentally during arthroscopy. We report a rare case of anomalous insertion of the medial meniscus into the anterior cruciate ligament with a brief review of the literature.

  Fig. 1 MR images of a 40-year-old man with anomalous insertion of the medial meniscus into the anterior cruciate ligament. A linear dark signal band arises from anterior horn of medial meniscus and runs parallel to the anterior cruciate ligament on sequential modified proton density (MPD) coronal (a) (clockwise direction) and sagittal (b) images of the right knee joint.
