The purpose of this study was to identify the presence of the anterior intermeniscal ligament of the knee and to study its attachment patterns and relationships to other anatomic structures within the knee. Fifty unpaired cadaveric knees were dissected. An identifiably distinct anterior intermeniscal ligament was found in 47 specimens (94%). The average length was 33 mm and the average midsubstance width was 3.3 mm. The average perpendicular distance from the anterior intermeniscal ligament to the anterior margin of the tibial insertion of the anterior cruciate ligament was 7.8 mm (range, 2.0 to 13.5).
