Abstract:
PURPOSE: To demonstrate the incidence and variation of the meniscofemoral ligament in Koreans. MATERIALS AND METHODS: A total of 100 MR studies of 95 patients were reviewed with special attention to the appearance and incidence of the meniscofemoral ligaments. The ligament of Wrisberg was classified according to proximal insertion: type I, insertion at the posterofemoral condyle ; type II, insertion at the distal portion of the posteriorcruciate ligament ; type III, insertion at the distal portion of the posterior cruciate ligament. On T2-weighted images, the high signal at the meniscal insertion of the meniscofemoral ligament was classified according to itsshape. RESULTS: The ligament o Humprey was observed in 17 cases and the ligament of Wrisberg was in 90:type I in41 cases;type II, 19 cases;type III, in 28 cases; unclassified, in 2 cases. In 77 cases, the cleft with high signal intensity was seen between the meniscofemoral ligament and the posterior cruciate ligament. CONCLUSION: From our results, the incidence of the ligament of Wrisberg on MRI was moe prevelant than the ligament of Humprey. An exact knowledge of the meniscofemoral ligament could be helpful in distinguishing it from pathologic lesions.
