Key Teaching Point

The oblique meniscomeniscal ligament (OMML) is a normal intermeniscal ligament variant that can closely mimic a bucket-handle meniscal tear if not carefully evaluated.

What It Is

• A type of intermeniscal ligament
• Reported prevalence: 1–4%
• Traverses the intercondylar notch, passing between the ACL and PCL

How It’s Named

Oblique meniscomeniscal ligaments are named by their anterior attachment site:

• Medial OMML:
  Anterior horn of the medial meniscus → posterior horn of the lateral meniscus
• Lateral OMML:
  Anterior horn of the lateral meniscus → posterior horn of the medial meniscus

Why It Matters

• Has signal intensity similar to meniscal tissue
• On sagittal images, it may resemble:
• This can lead to overcalling pathology

How to Differentiate from a Bucket-Handle Tear

• Follow the structure on sequential coronal images
• Identify continuity from anterior horn to opposite posterior horn
• Confirm normal meniscal body size and shape

👉 Normal meniscus + intercondylar crossing band = think OMML, not tear

Take-Home Message

If the meniscus looks normal everywhere else,
don’t call it a bucket-handle tear.
Follow it—it may be an oblique meniscomeniscal ligament.
