ABSTRACT
Meniscal ossicles are small fragments of cancellous bone containing bone marrow surrounded by meniscal cartilage. Two cases of meniscal ossicle are reported, one found during routine dissection of the knee joint and the other as an incidental finding on magnetic resonance imaging (MRI). It is a rare entity and is usually located in the posterior horn of the medial meniscus. Cases have been reported since the 1930s in imaging methods. Its association with meniscal tear is common, as it occurred in the reported case. Its origin is discussed, proposing that they may represent vestigial remnants of development or that they have a post-traumatic origin. They are usually asymptomatic, being an exceptional cause of knee pain. MRI is the method of choice for its evaluation, allowing to distinguish a meniscal ossicle from other intra-articular entities, such as a free body or an intrameniscal calcification. A review of the literature is also presented
