What is Intrasubstance degeneration of the medial meniscus?
What is Intrasubstance degeneration of the medial meniscus?
Meniscal intrasubstance degeneration (MID), defined by increased intrameniscal signal on MRI that does not fulfil the criteria for a meniscal tear, is a frequent finding on MRI knee examination of older adults without radiographic OA or meniscal tears [7], and it may play a role in the development of knee OA [8,9].
What is altered signal intensity?
Alterations in muscle signal intensity seen in pathologic conditions usually fall into one of three recognizable patterns: muscle edema, fatty infiltration, and mass lesion.
What is hyperintense signal?
A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss.
When is altered signal intensity in the posterior horn of the meniscus?
Altered signal intensity in the posterior horn of the medial meniscus: an MR finding of questionable significance A meniscal tear is unlikely when MR shows a focus of high signal intensity in the posterior horn of the medial meniscus that does not unequivocally extend to involve the inferior or superior joint surface.
What is the difference between meniscal tears and intrasubstance tears?
This is a critical differentiation because the latter represents meniscal tears that can be found and treated arthroscopically, whereas the former represents degeneration, intrasubstance tears or perhaps normal variants that are not amenable to arthroscopic intervention.
Are there Tears of the posterior horn of the medial meniscus?
There were 48 men and 16 women. Their mean age was 28.2 years. Results: Tears of the posterior horn of the medial meniscus were diagnosed unequivocally (grade 3 signal) in 18 patients and equivocally (grade 2/3 signal) in 10 patients.
What does ” intrasubstance intermediate signal within the…?
After going through your query I concluded that you are having degenerative changes of meniscus. You are already taking glucosamine, Chondroitin, calcium, vitd3 and trace element supplements. You are already doing physiotherapy .I generally recommend in addition to these supplements Diacerine to such persons coming to my clinic with good results.

What does intrasubstance degeneration of the medial meniscus mean?
I had an MRI done on my left knee (the worst of the two) – the summary stated that I have an “Intrasubstance Degeneration of the Posterior Horn of the Medial Meniscus” but otherwise nothing of note. Can someone please let me know what this means, what the best course of action should be, and the outlook as per the various treatment (s) stated?
