Abstract

Menisco-meniscal ligaments in knee joint are known as four variants, anterior and posterior transverse meniscal ligament, medial and lateral oblique menisco-meniscal ligament. The ligament which originates from the anterior horn of the meniscus and attached to the posterior horn of the same meniscus, so-called unilateral menisco-meniscal ligament is extremely rare in English literature. The authors experienced a case of medial unilateral menisco-meniscal ligament with posterior horn tear of the medial meniscus in a 49-year-old man. We report this case with a review of literature.

  Figure 1 (A) T2-weighted magnetic resonance image of sagittal view of the knee shows a code like low signal intensity structure (white arrows) on the tibial spine from the anterior horn of the medial meniscus to the posterior one of the medial meniscus. (B) T2 weighted magnetic resonance image of coronal view shows a point like low signal intensity structure (white circle) on just the medial side of the tibial spine.

  Figure 2 Arthroscopic findings show a code like structure on the tibial spine from the anterior horn of the medial meniscus to the posterior one of the medial meniscus and anchored to the posterior horn of the medial meniscus into a hole. Medial FC, medial femoral condyle; Medial TC, medial tibia condyle; MMPH, medial meniscus posterior horn.
