Bilateral discoid medial menisci: A case report and literature review

https://doi.org/10.1016/S0749-8063(05)80427-XGet rights and content

Summary

The purpose of this article is to present the fourth case report of bilateral discoid medial menisci. A previously unreported anomaly of the tibial plateaus associated with the discoid menisci was also present bilaterally. The patient was treated successfully by excision of the central anomalous discoid portion of the menisci, using arthroscopic techniques.

      Citation Excerpt :

      The osteochondral injury to the femoral medial condyle was caused by damaged meniscal margins, and this injury damaged the tibial cartilage. Discoid medial meniscus, a rare congenital anomaly, was first reported by Cave and Staples,4 and fewer than 70 cases have been reported in the literature.5-7 Various clinical symptoms of discoid meniscus have been reported: Discoid lateral meniscus tends to manifest as hypermobility during childhood without tearing, whereas discoid medial meniscus is asymptomatic in childhood until shown by a tear.8,9

      Young [2] reported the first case of discoid lateral meniscus in 1889. Cave and Staples [3], in 1941, reported the first two cases of partially discoid medial meniscus, a rare congenital anomaly with less than 70 cases in the literature [4–27]. A retrospective study including 14,731 menisci assessed incidence of discoid medial meniscus at 0.12%, compared to 1.5% for discoid lateral meniscus [14]; bilateral cases were even more rare (0.012%).

      Plain film radiographs may demonstrate increased joint space height, hypoplasia of the femoral condyle with squared morphology, superior migration of the femoral head, and cuplike deformity of the tibial plateau.39 Sagittal MR imaging demonstrates a continuous bow-tie appearance of the meniscus with loss of central tapering.39,40 Both sagittal and coronal MR imaging demonstrate an increase in height of a discoid meniscus relative to the normal adjacent meniscus.41
