🤔Discoid Meniscus Overview:

• The discoid meniscus of the knee is a congenital or developmental variant with a thick, disc-like shape and central hypertrophy, leading to an increased width of the meniscal body. 
• It typically lacks standard posterior meniscocapsular and ligamentous attachments, with the ‘discoid meniscus’ term covering a broad spectrum of shapes and stability levels, mainly affecting the lateral meniscus.

 

🤔Type I:

• A complete discoid lateral meniscus, characterized by a block-shaped structure that spans the entire tibial plateau width, maintaining normal posterior capsular attachment.

🤔 Several indirect signs of a discoid lateral meniscus

 

- Changes in lateral tibial spine height

- Lateral joint space height

- Fibular head height

- Lateral tibial plateau obliquity

- The condylar cut-off sign

- Squaring of the lateral femoral condyle

- Cupping of the lateral tibial plateau

- A lateral femoral condylar notch
