Three patients with an arthroscopically proved normal variant, the oblique meniscomeniscal ligament, underwent prospective magnetic resonance (MR) imaging of the knee. In the first case, the ligament was misinterpreted as a displaced flap tear of the posterior horn of the lateral meniscus. In the two subsequent cases, the ligament was identified correctly at MR imaging as the oblique meniscomeniscal ligament.
