Discoid Meniscus Injury
When a discoid meniscus, often affecting the lateral meniscus, tears, treatment is typically necessary to address the associated symptoms. Most of the time, the meniscus is quite thin and degenerated when it tears, requiring a significant portion to be removed. Efforts are made to restore a more normal shape to the lateral meniscus by trimming the edges, leaving some healthy meniscal tissue intact.
In rare cases, a thick discoid meniscus may tear at the capsular junction, where there is still a blood supply. These instances often occur at the far anterior or posterior horns of the discoid meniscus. In such unique situations, where a portion of the meniscus remains intact, attempts can be made to repair the torn meniscus rather than removing it.
