🔵🇰🇷Tear of popliteomeniscal fascicles
- When assessing a knee for a hypermobile lateral meniscus (LM), it's important for the radiologist to concentrate on the anteroinferior and posterosuperior popliteomeniscal fascicles (PMFs).
- This is because a total rupture or lack of these structures correlates with a significantly higher likelihood (with odds ratios of 12 and 6, respectively) of a hypermobile LM.
- Despite some controversy, there are surgeons who advocate for repairing all instances of symptomatic LM instability when an MRI and arthroscopy confirm a PMF tear.

🔵🇰🇷Normal popliteomeniscal fascicle deficiencies
- The normal absence of the anteroinferior popliteomeniscal fascicle allows the popliteus tendon to traverse from the lateral to the medial side through the hiatus.
- A slice further medially through the hiatus reveals this normal deficiency of the fascicle.
