Large‐Scale Analysis of Meniscus Morphology as Risk Factor for Knee Osteoarthritis
Authors' conclusion
This automatic method expanded upon known meniscus characteristics that are associated with the onset of OA and discovered novel shape features that have yet to be investigated in the context of OA risk.
Study context
- Population
- Participants from the Osteoarthritis Initiative data set
- Participants
- 4,790 participants
- Exposure
- Knees that develop osteoarthritis (OA) vs knees that remain normal
- Outcome
- Variations in meniscal shape and their relationships to tissue morphology, OA onset and longitudinal changes in cartilage thickness
- Follow-up
- 8 years

Main finding
As reported in the abstract
Meniscal shape features differing between knees that develop OA and those that remain normal
- Seven shape features between the medial and lateral menisci differed between knees that remain normal and those that develop OA (length-width ratios, horn lengths, root attachment angles, concavity)
- 7
Observational data: associations, not effects.
Further findings
"At-risk" shapes and cartilage thickness changes · 8 years
- At-risk shapes linked to unique cartilage thickness changes suggesting a relationship between meniscus geometry and decreased tibial coverage and rotational imbalances
Meniscal shape and other characteristics
- Strong associations between meniscal shape and demographic subpopulations, future tibial extrusion, and meniscal and ligamentous tears
