Abstract

We present a case of a rare incidence of a RAMP-type tear of the external meniscus in a 21-year-old male patient, in which a repair with vertical meniscal sutures was performed. This is a scarcely described tear in the literature that is associated with anterior cruciate ligament (ACL) injuries.

We report our experience with a case treated at our center, where we identified this distinct injury of the posterior horn of the external meniscus. Although Magnetic Resonance Imaging may reveal fluid posterior to the posterior horn of the lateral meniscus in a longitudinal configuration, the definitive diagnosis is made through arthroscopy. The chosen treatment was to close the defect with vertical meniscal sutures. We believe that more studies are needed to determine the ideal management.
