🤔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
