Posterior medial meniscus-femoral insertion into the anterior cruciate ligament. A case report.
Medial meniscal anomalies are rare. The anterior horn insertion into the anterior cruciate ligament is the most common. In the course of an arthroscopy for torn lateral meniscus, an anomalous band in continuity with the posterior horn of the medial meniscus was observed to insert into the anterior cruciate ligament. Although the tibial portion of the anterior cruciate was redundant, the anomalous band provided tension to the anterior cruciate ligament and a negative pivot shift. A previously unreported posterior medial meniscal femoral insertion is described.
