This is different from a degenerative tear, which results from repetitive normal forces acting upon a worn down meniscus. Tears can also be described based on pattern and location.
What is a degenerative torn meniscus?
Overview. Pathology – a tear that has developed gradually in the meniscus. Considered a feature of knee osteoarthritis. Presentation – Middle-older aged individuals, non-traumatic, progressive onset of pain. Pain is typically medial and activity-related (e.g. pivoting).
How is internal derangement of knee diagnosed?
The Ottawa Knee Rule can help physicians determine which patients require radiography. Positive physical examination tests and findings of acute effusion suggest internal derangement. An abnormal McMurray or Thessaly test strongly suggests meniscal injury, whereas a normal Thessaly test may rule out meniscal injury.
