This case report presents the MRI findings of aplasia of the anterior cruciate ligament with associated hypoplasia of the posterior cruciate ligament (Manner type 2). Radiographically the presence of a shallow femoral notch and hypoplastic tibial spines (the so-called "dromedar" sign) can aid in the diagnosis. Operative treatment is often not indicated since the congenital absence of the ACL implies long-standing altered biomechanics to which the knee has well adapted in the majority of cases.
