Abstract
Examination of the knee joint by magnetic resonance imaging (MRI) is a noninvasive technique of proven reliability as regards lesions of the menisci and ligaments. It provides good definition of the different anatomic structures. The meniscofemoral ligaments have been observed with varying frequency and may be responsible for false images. However, it is important to detect them in cases of hypermobile discoid menisci of the 'Wrisberg ligament type' in order to guide the surgeon in their excision during total meniscectomy. We have attempted to assess the ability of MRI to visualise the meniscofemoral ligaments in correlation with an anatomic study and to identify certain anatomic pitfalls. This study will allow better investigation of the hypermobile menisci associated with the meniscofemoral ligaments. A clinical case is reported to illustrate its practical importance.
